Paying for Public EV Charging Without an App or Subscription (2026)
A federal rule has required contactless card payment at newly built public chargers since March 2023. In August 2026, the network most drivers actually use — Tesla's Supercharger system — still has no card reader at all.
By Liam Whitcombe, EV Ownership & Running-Cost Analyst · Published August 11, 2026 · Data current to Q3 2026
Every EV-charging guide assumes you have a smartphone, a data connection, and the patience to install one more app before you can move your car. Most of the time that assumption holds. It breaks down at the exact moments that matter most: a dead phone battery on a road trip, a rental car with no network account attached to your name, a rural stall with no signal, a relative visiting from out of state who does not want to hand over an email address to eight different companies, or simply a driver who does not want six charging apps competing for a home-screen icon. The practical question — can I just tap a card or a fob and charge, the way I buy gas — has a real, if uneven, answer in 2026, and it depends entirely on which network's logo is on the pedestal in front of you.
This article works through that answer network by network: physical RFID cards and fobs, tap-to-pay credit card readers, Tesla's Magic Dock, and Plug & Charge — the ISO 15118 standard that authenticates a car and a charger to each other with zero taps at all. It also covers the one piece of federal law that already forces some of this, the states pulling in opposite directions on it, and what actually happens when your phone has no signal. It does not re-litigate what any of this costs; for network pricing, see ChargeCostLab's cost comparison across US networks, and for the fees that show up regardless of how you pay, see the guide to fees beyond the kWh rate.
Payment method and price are genuinely separate questions, and it is worth being explicit about why this article stays on one side of that line. A driver who never learns which networks offer a card reader will still find a way to pay eventually — the app download takes two minutes on a good connection. What a card-free or app-free option actually buys is resilience against the specific failure modes that make that two minutes turn into twenty: a phone that will not update, a data connection that will not load a login screen, an account creation flow that wants a photo of a driver's license before it will let a stranded driver plug in. Those failures are rare in aggregate but concentrated exactly where drivers are least able to absorb them, which is the throughline connecting a federal accessibility rule, a handful of network FAQs, and a driver standing at a dark charger with 40 miles of range left.
Federal law already requires card readers — but only at NEVI-funded stations
23 CFR 680.106(f) requires any charging station built with National Electric Vehicle Infrastructure (NEVI) formula funds to offer "a contactless payment method that accepts major debit and credit cards, and either an automated toll-free phone number or a short message/messaging system (SMS)" [1][2]. The same subsection bars operators from requiring a membership to use the station, and from throttling power based on payment method [1]. The rule defines a contactless payment method as a secure method using RFID or near-field communication technology via a debit card, credit card, smartcard, mobile application, or other payment device [3].
That is a real, binding rule, and it is the closest thing the US has to a "pay by card" mandate for EV charging. It is also narrower than it sounds, because it applies only to chargers built with NEVI money — a five-year, $5 billion federal program running through fiscal year 2026 [4][5]. As of August 10, 2026, states had obligated roughly $665 million of that $5 billion to actual charging projects, about 13% of the total apportionment [5]. Progress has not been linear: an executive order in January 2025 paused disbursement of NEVI and other infrastructure funds, and FHWA rescinded its prior program guidance the following month, freezing new state awards at roughly $527 million obligated [6][7]. A coalition of 16 states and Washington, D.C. sued, a federal court ordered the funds released in mid-2025, and FHWA issued revised guidance that August restoring the program [8][9]. The upshot for a driver on the road today is unglamorous but important: NEVI's card-reader requirement only reaches the fraction of the national charging fleet actually built under the program, which after the freeze-and-restart cycle is still a modest — though growing — slice of total US charging infrastructure [10].
The NEVI rule was not written only for drivers who dislike apps. Subsection (f) requires that payment methods at these stations be accessible to people with disabilities, and that the toll-free phone number and SMS option "clearly identify payment access" for drivers with limited English proficiency [1]. That framing matters because it changes who the app-free requirement is actually protecting: not just the road-tripper who forgot to charge their phone, but a driver who cannot reliably operate a small touchscreen, or one who cannot read an app's onboarding flow in English. A contactless card reader and a toll-free line solve both problems with the same piece of hardware, which is presumably why the rule specifies both rather than leaving the app as an acceptable substitute on its own. No equivalent accessibility requirement exists for chargers built without NEVI money, which is one more reason the network you happen to be standing in front of, rather than any blanket federal standard, still decides what your options are.
Physical RFID cards and fobs still exist — at three of the five biggest networks
ChargePoint, EVgo and Blink are the three of the five biggest US fast-charging networks that still issue a physical RFID card, one that authenticates at a reader with no app open; Electrify America and Ionna are the two that do not offer one at all. EVgo includes three free RFID program cards with every primary account and frames the card explicitly as a signal-independent backup, not a legacy afterthought [18]. That card is not an instant fix, though: EVgo's own materials note shipping takes roughly 10 to 14 business days after activation, so a driver who wants an app-free fallback needs to request the card well before the trip where they might need it, not the morning of [18]. ChargePoint's own support page confirms a driver "can charge your car without a ChargePoint card" by using the app, which implies the reverse is equally true — the card works without the app open once it is activated and linked to a payment method [12]. Blink's driver FAQ describes the same mechanic: hold the Blink Card to the RFID reader and follow the on-screen prompts [23].
Electrify America is the clean exception on the other side. Its own mobile FAQ states plainly that the network "does not offer RFID cards" — instead, every charger has a built-in credit card reader, and Pass/Pass+ members can tap a phone-based digital pass at the reader instead of a physical card [16]. Ionna, the automaker-backed network built by BMW, GM, Honda, Hyundai, Kia, Mercedes-Benz, Stellantis and Toyota, follows the same pattern: no RFID card of its own, but a credit-card reader that accepts a tap, swipe or insert at every stall, and ChargePoint's RFID cards specifically do not work at Ionna stations even though ChargePoint issues them elsewhere [24]. The practical rule for a driver carrying a wallet full of RFID cards from other networks: don't assume interoperability. A card that works at one network's charger is not guaranteed to work at another's, roaming agreements notwithstanding.
One real caveat sits inside even the RFID option. Every network that issues a card still requires that card be requested, activated and linked to a payment method through the app or website first [12][18][23]. None of them offer true walk-up, no-account, card-only charging the way a gas pump does. The RFID card removes the app from the moment you're standing at the charger — it does not remove the app from the process entirely.
The RFID card is also not a settled feature everywhere the network operates. ChargePoint announced in mid-2026 that it is winding down app and RFID access in Europe for private drivers who are not enrolled through an employer, fleet operator or leasing company, closing those accounts on June 30, 2026 and pushing them toward contactless bank cards and roaming apps instead [38][39]. That change is specific to ChargePoint's European operation, not its US network, and ChargePoint's own US support pages covering RFID cards showed no equivalent change as of this research [12]. It is still a useful data point: the direction of travel on app-free access is not a straight line even within a single company, and a driver relying on an RFID card for a specific network abroad should check that network's current policy rather than assume US practice carries over.
EVgo's own driver-facing materials lay out the full menu rather than treating the RFID card as an afterthought: the network lists five distinct ways to start a session — the app, the RFID program card, a credit card reader where installed, Autocharge+, and a fallback to creating an account on the spot if a station lacks a reader — and explicitly frames the card and the reader as parallel options to the app rather than a downgrade from it [40]. That framing is itself informative about how the network thinks about the problem: EVgo treats "no app" as a normal use case to design for, where several other networks treat it as an edge case to work around.
Tap a credit card at the charger: reliable at two networks, spotty everywhere else
Electrify America and Ionna are the two networks where a driver can walk up with nothing but a physical credit or debit card and charge, no account, no app, ever. Electrify America's FAQ states every one of its more than 5,000 chargers has a credit card reader [16][17], and Ionna's FAQ confirms the same for tap, swipe or insert with no account required [24]. Rivian's Adventure Network adds a tap-to-pay credit card reader at the growing subset of its chargers open to non-Rivian EVs — over 850 individual chargers network-wide as of Rivian's most recent published count — alongside its own account-based auto-start for owners [31][32].
ChargePoint and Blink both fall short of a guaranteed card reader, for a structural reason: most of their stations are independently owned rather than network-owned, and ChargePoint's own support pages describe the "Overstay Rate" and payment options as something "each station owner can set differently" [11][13]. ChargePoint's answer for a driver with neither card nor account is to call the phone number posted on the unit and follow an automated prompt — functional, but a genuine downgrade from tapping a card [12]. Blink offers something closer to a real fallback at its Series X chargers: an automated voice line that takes a credit card over the phone to start a session, no app or card required at all [23]. Shell Recharge (the rebranded Volta network) sits in a messier spot — it supports an RFID card as an alternative to its app, but multiple drivers have reported getting stuck in an app-only loop at Level 2 stations where the app has no field to enter payment at all, forcing a workaround through the RFID card or Shell's separate driver portal [36].
ChargePoint's own consumer-facing "Tap to Charge" feature is worth separating from a true contactless credit card tap, because it is easy to confuse the two. Tap to Charge uses NFC to read a virtual card stored in the ChargePoint app on your phone or Apple Wallet — it removes the physical plastic card, but the app still has to be installed and signed in beforehand to set the virtual pass up [14][15]. It is a smoother version of the RFID card, not a path around the app entirely.
Plug & Charge means zero taps — after one app-based setup
ISO 15118 "Plug & Charge" authenticates a vehicle and a charger to each other automatically the instant the connector clicks in, using cryptographic certificates rather than a card swipe or app tap, and bills the session to whatever payment method is on file [22][28]. It is the only payment method in this article with genuinely zero interaction at the charger — no phone out, no card, no screen. The tradeoff, and it is real, is that it requires a one-time enrollment through an app before that magic works, which means Plug & Charge removes the app from every session after the first, not from the concept altogether.
Adoption on the charging-network side has moved fast in the past year. Electrify America had nine automakers live on its Plug & Charge implementation as of late September 2025, including Audi, BMW, Ford, Lucid, Mercedes-Benz, Porsche, Volkswagen and, as the newest addition, Nissan starting with the 2026 LEAF [17]. ChargePoint announced in December 2025 that its entire current hardware portfolio supports Plug & Charge at the equipment level, positioning 2026 as the year the feature reaches drivers network-wide [29]. Ford's BlueOval Charge Network extended Plug & Charge to its own dealer chargers and to Ionna stations in late 2025, building on existing support at Electrify America [30]. EVgo's version, branded Autocharge+, uses a slightly different mechanism — matching the car's charging-port data rather than a full ISO 15118 certificate exchange — but achieves the same driver experience, and the network reports roughly 30% of its sessions now start this way [19][20][28].
Not every "no-tap" system is built the same way underneath, and the distinction affects how much you should trust it. EVgo's Autocharge+ and similar early systems use a simpler method sometimes called Autocharge, which registers a vehicle's charging-port hardware identifier and matches it to an account on the network's backend — fast to deploy, but described by one charging-hardware executive as "insecure" and "sort of a hack" compared with the alternative [28]. True Plug & Charge under ISO 15118 instead runs a cryptographic handshake, using public-key certificates and TLS encryption to verify the car and the charger to each other before any billing happens, which is why automakers and networks increasingly treat it as the long-term standard rather than a stopgap [28]. A driver at the charger cannot tell which system they are using — both feel identical, a plug-in and nothing else — but the security model underneath is meaningfully different, and industry sources expect the simpler Autocharge-style systems to be phased out as ISO 15118 hardware becomes standard across new chargers [28][29].
Coverage is still uneven by automaker, and that unevenness is worth stating plainly rather than smoothing over. Hyundai and Kia advertise ISO 15118-capable hardware on the Ioniq 5, Ioniq 6, EV6 and EV9, but neither brand appeared on Electrify America's own list of nine supported automakers as of the September 2025 announcement [17] — a gap between a spec sheet claim and a live, working integration on a specific network that a shopper should check per vehicle and per network rather than assume. Blink, similarly, lists Plug & Charge only as a "planned upgrade," not a shipped feature, on its current driver FAQ [23]. The pattern across the industry is consistent: the standard is real and increasingly deployed, but "my car supports ISO 15118" and "my car will Plug & Charge at this specific station today" are two different claims, and only the network's own current support page settles which one is true. This is a different technology from NACS adapters, which solve connector shape, not payment.
Tesla Superchargers are the one major network with no app-free path at all
Tesla Superchargers, including Magic Dock stalls that carry a built-in NACS-to-CCS1 adapter for non-Tesla EVs, have no credit-card reader and no RFID pad anywhere in the US network [25][26]. A Tesla owner's own car authenticates automatically once plugged in, which feels like Plug & Charge but is a closed, Tesla-account-bound system rather than the open ISO 15118 standard other networks use [25]. A non-Tesla driver at a Magic Dock stall gets none of that convenience: Consumer Reports and independent charging guides both confirm the driver must download the Tesla app, create an account, add a payment method and explicitly select the option to charge a non-Tesla vehicle before the connector will dispense power [25][26].
Tesla has moved on this front, but only for fleets, and only outside the US so far. In 2026 the company opened its European Superchargers to more than 30 third-party fleet fuel-card providers, letting commercial drivers bill sessions directly to an employer's account [27]. Even that expansion still routes through the Tesla app — a driver adds the fleet card inside the app rather than tapping it at the charger — and there is no indication of an equivalent RFID or card-reader rollout for US Superchargers as of this writing [27]. For the roughly 20,000 US Supercharger stalls a driver might encounter, the practical reality in 2026 is unchanged from prior years: no app, no charge, for Tesla and non-Tesla drivers alike.
Tesla's position here is also, on the evidence in this article, an outlier of choice rather than of technical limitation. The company operates its own hardware end to end and, until the Magic Dock and NACS-adapter era, served an almost entirely captive fleet of its own cars already tied to a Tesla account — the two conditions that made card readers and RFID pads worth the retrofit cost at Electrify America and Ionna were never as pressing for a network whose typical customer had already opened the app to buy the car. Non-Tesla Magic Dock traffic changes that calculus for other networks, if not yet visibly for Tesla's own deployment choices; none of the sources reviewed here point to a stated Tesla roadmap for US card or RFID support.
When your phone has no signal, the RFID card is the only network-endorsed fallback
Public charging infrastructure skews toward exactly the locations where cell coverage is weakest: interstate corridors through mountain passes, rural highway exits, parking structures with concrete overhead. EVgo addresses this directly rather than treating it as an edge case — its help center describes the RFID program card as "a great backup if you are charging in a location with a poor signal," because the card authenticates locally at the reader instead of depending on a live data connection to load an app [18]. That is a materially different design position from networks that offer no non-app path at all, where a dead data connection simply means a dead charging attempt.
Blink's toll-free automated phone line offers a second kind of fallback — one that depends on cell voice service rather than data, which in practice survives in more rural dead zones than a data-hungry app does [23]. Neither option is universal: ChargePoint's phone-based fallback still assumes the driver can reach a live person or automated system by voice, and Tesla and Rivian's automatic-start systems depend entirely on the car's own connectivity, with no card-based workaround if that connection fails [12][31]. The single most robust app-free setup, on the evidence here, combines a network offering both a physical RFID card and a phone-based backup — EVgo and Blink both qualify; Electrify America and Ionna substitute a universally reliable card reader instead, which sidesteps the connectivity question altogether since a credit card reader does not need the driver's phone to have signal at all [16][24].
Connectivity friction is not a niche complaint. J.D. Power's 2025 EVX Public Charging Study found that 14% of EV owners visited a public charger at some point in the year without successfully completing a charge, an improvement from 19% the year before but still roughly one visit in seven [37]. The study does not break that failure rate down by cause, and app or connectivity problems are only one contributor alongside broken hardware and occupied stalls [37]. But an app-dependent session has more points of failure than a card-swipe one by design — the phone has to have a charge, the phone has to have signal, the app has to load, the app has to recognize the charger, and only then does the actual charging start. Every payment method that skips one of those steps removes one more way for the visit to fail before a single kilowatt-hour is delivered.
States are pulling in two directions on the app requirement at once
California's payment-method law is the country's first EV-specific card mandate, and it has been both tightened and loosened since the underlying open-access law, Senate Bill 454, was enacted in 2013. CARB's resulting Electric Vehicle Supply Equipment (EVSE) Standards Regulation, adopted in 2019, required EMV chip card readers and NFC contactless hardware on public chargers on a phased schedule — new DC fast chargers by January 1, 2022 and new Level 2 stations by July 1, 2023, with existing equipment given until July 1, 2033 to comply [33]. The industry pushed back on the cost and practicality of the EMV chip piece specifically: CARB's own background materials put the added hardware cost at roughly $371 per charger upfront plus about $270 a year in ongoing maintenance, and charging-hardware maker ClipperCreek shelved its own EMV-equipped Level 2 unit after concluding it could not find a card-reader supplier durable enough for unattended outdoor installation [33]. The EMV chip mandate itself was subsequently narrowed by a 2023 amendment (SB 123) that aligned California's rule more closely with the federal NEVI contactless-payment standard. The state's separate DC-fast-charger rule — California Health and Safety Code §§44268 and 44268.2, in force since July 10, 2024 — requires public chargers to allow contactless payment and pay-by-phone methods, bars subscription or membership requirements, and, going further than the federal NEVI rule, requires DC fast chargers specifically to include Plug & Charge payment capability [35].
In the same 2025-2026 legislative session, California moved the opposite direction in one narrow case. Senate Bill 533 carves out an exception allowing an EV charging station to require an internet-based application for payment when that charger sits inside a facility — the bill's own analysis names arenas such as the Intuit Dome — that is itself only accessible through that facility's app [34]. It is a narrow, venue-specific exception rather than a reversal of the general contactless-card rule, but it is a real, dated instance of a state legislature explicitly authorizing app-only payment in 2026, in the same year and the same state that otherwise leads the country on mandating card access. No other state currently imposes a payment-method mandate as detailed as California's; the federal NEVI rule remains the only nationwide floor, and it only reaches NEVI-funded stations [1][35].
Which network to prioritize depends on who is charging, not just where
The right network is different for a one-time driver than for a regular owner: a road-tripper renting an unfamiliar EV for a week has a different problem than a longtime owner who simply dislikes app clutter, and the two should not default to the same network. For a one-time or occasional driver — a rental, a loaner, a relative's car — the reliable move is to route toward Electrify America or Ionna chargers specifically, because both guarantee a station-level credit-card reader with no account or app step at all [16][24]; that is the closest US public charging currently gets to paying for gas. For a driver who owns the car and charges the same network repeatedly, an RFID card from ChargePoint, EVgo or Blink is worth requesting once, since the one-time app-based setup pays off on every subsequent visit and, per EVgo's own guidance, doubles as insurance against a dead-zone charging stop later [12][18][23].
Drivers whose vehicle already supports Plug & Charge have the least reason to think about any of this at all, provided they confirm — rather than assume — that their specific automaker-network pairing is live. A Ford, Volkswagen, Mercedes-Benz, BMW, Audi, Porsche, Lucid or Nissan owner charging on Electrify America, or a Ford owner on the expanding BlueOval/Ionna pairing, can enroll once in an app and then genuinely never touch a phone at the charger again [17][30]. A Hyundai or Kia owner should not assume the same, since neither brand was on Electrify America's own supported list as of the most recent count available for this research, regardless of what the vehicle's spec sheet advertises [17]. And a Tesla or non-Tesla driver planning to use a Supercharger, Magic Dock included, should simply accept the Tesla app is mandatory and set it up before leaving the driveway — there is no card, fob or phone-line workaround to fall back on at that specific network [25][26].
Two groups deserve a more deliberate plan than "download whatever app the charger tells you to." An out-of-country visitor renting an EV, or an older relative who does not want a new account tied to a new phone number, is exactly the population the NEVI rule's accessibility language was written for — and the practical translation of that rule is to route them toward Electrify America, Ionna or a Rivian all-EV site, where a card is the entire interaction [1][16][24][31]. A household that charges regularly at one network but occasionally needs a backup — a second driver, a loaner car while the regular EV is in for service, a trip where the primary phone stays home — is better served requesting an RFID card ahead of time from EVgo, ChargePoint or Blink than trying to solve the problem at the charger itself, given the 10-to-14-day shipping lag on a fresh card [18].
| Network | RFID / fob card | Card reader at charger | Plug & Charge / Autocharge | App-free session possible? |
|---|---|---|---|---|
| Electrify America | No RFID offered [16] | Yes, every charger [16] | Yes, 9 automakers as of Sep 2025 [17] | Yes |
| Ionna | No (ChargePoint RFID not accepted) [24] | Yes — tap, swipe or insert [24] | Yes [24] | Yes |
| EVgo | Yes, 3 free per account [18] | Most stations, not all [22] | Yes, Autocharge+ [19][20] | Yes |
| ChargePoint | Yes, mailed on request [12] | Rare — set by individual station host [13] | Hardware Plug & Charge-ready across the fleet since Dec 2025, not yet a driver-facing enrolled feature network-wide [29] | Yes, with an activated RFID card |
| Blink | Yes [23] | Rare — host-set; some Series X sites take a phone-in card payment [23] | Announced as a planned upgrade, not yet live [23] | Yes, RFID or phone line |
| Rivian Adventure Network | No RFID offered [31] | Yes, at sites open to all EVs [31] | Automatic start, but tied to a Rivian account, not open ISO 15118 [31] | Yes, card reader at all-EV sites |
| Tesla Supercharger / Magic Dock | No [25][26] | No [25][26] | Automatic start for Tesla-account vehicles only; Magic Dock (non-Tesla) still routes through the Tesla app [25][26] | No — the Tesla app is the only path |
Key findings
These 5 findings summarize the payment-method landscape across the networks covered above.
- ChargeCostLab's research finds a clear split among the five biggest US fast-charging networks: EVgo offers the most app-free payment channels (RFID card, most stations' card reader, and Autocharge+), while Tesla Superchargers offer none at all, per each network's own support documentation [18][21][25][26].
- The federal NEVI rule has required contactless card payment at newly built federally funded chargers since March 30, 2023, but only about 13% of the program's $5 billion five-year budget had actually reached charging projects as of August 2026, following a year-long funding freeze in 2025 [1][5][6].
- Electrify America and Ionna are the only two networks confirmed to offer a credit-card reader at effectively every station, making them the most reliable app-free option regardless of cell signal [16][24].
- Plug & Charge adoption reached nine automakers on Electrify America by September 2025 and roughly 30% of sessions on EVgo's Autocharge+ variant, but coverage is inconsistent enough by automaker and network that "ISO 15118-capable" on a spec sheet does not guarantee a zero-tap session at a specific charger [17][28].
- California is the only state with a detailed statutory payment-method mandate, requiring both contactless card payment and Plug & Charge capability at DC fast chargers, while a narrower 2025-2026 state law simultaneously permits app-only payment inside app-gated venues — evidence that even the most aggressive state on this issue is not moving in a single direction [34][35].
Frequently asked questions
The answers below are self-contained; full source attributions are in the sources list.
Methodology note
Every claim about a specific network's payment options is drawn from that network's own current support, FAQ or press page, read directly wherever accessible; where a primary page blocked automated retrieval, the claim is corroborated against independent reporting and both sources are cited. Federal and state legal requirements are read from the current Code of Federal Regulations, Federal Register text and a state government's own Alternative Fuels Data Center summary rather than secondary paraphrase. The two comparative tallies — app-free payment channels per network, and the payment-method comparison table — are ChargeCostLab's own classification against a fixed, stated test, not a figure published by any single source; every other number is a cited fact, dated to the month it was published or last confirmed.
Methodology & sourcing
Scope. This article covers payment method, not price, for public EV charging in the United States in 2026: which networks let a driver pay with a physical RFID card or fob, a tap-to-pay credit card, or fully automatic Plug & Charge (ISO 15118) — and which still require that network's own app for every session. Home charging and network price comparisons are out of scope and covered elsewhere on this site.
Regulatory sources. Federal payment requirements come from 23 CFR 680.106(f), the National Electric Vehicle Infrastructure (NEVI) standards rule, read directly from the current electronic Code of Federal Regulations and its companion Federal Register notice [1][2][3]. NEVI program funding and obligation figures come from a funding tracker built on FHWA apportionment data and USASpending.gov obligation records, plus contemporaneous reporting on the 2025 funding freeze and its resolution [5][6][8][9][10]. California's state-level payment statute is read from the Department of Energy's Alternative Fuels Data Center summary of state law [35].
Network sources. Every claim about a specific network's payment options — ChargePoint, Electrify America, EVgo, Blink, Ionna, Rivian's Adventure Network, and Tesla Superchargers including Magic Dock — is drawn from that network's own support, FAQ or press pages wherever those pages were reachable, cross-checked against independent reporting where a primary page blocked automated retrieval [11]-[32]. Plug & Charge / ISO 15118 adoption figures (which automakers, which networks, as of what date) are taken from network press releases and trade press, and are explicitly dated because adoption is changing month to month.
What is calculated vs. cited. The two payment-method tallies in this article — the count of app-free payment channels per network, and the comparison table — are our own classification, built by reading each network's current published policy against a consistent three-channel test (RFID/fob, physical card reader, Plug & Charge/Autocharge). Every dollar and percentage figure is a cited number, not an estimate; where a network's own documentation was ambiguous or contradicted by user reports, that disagreement is stated rather than resolved by guessing.
