Both methods start and manage charging sessions, but they put the credential in different places. RFID puts it on a physical card or fob the driver taps on the charger. App control puts it in an account on the driver’s phone. The difference shows up in who can use the charger, what the site administers, and what still works when a phone or a network lets you down.
Key Takeaways
- RFID puts the credential on a card; app control puts it in a phone account. The charging is the same once a session starts.
- Cards win on guests, simplicity and phone-free use; apps win on reach, live information and zero issuing.
- Offline behaviour belongs to the charger and platform configuration — check the platform’s documentation, not the brochure.
- Shared sites commonly run both, as the EV-ACT3204E does with RFID and app control on one wallbox.
The Two Methods Side by Side
| Dimension | RFID card or fob | App control |
|---|---|---|
| What the driver carries | A card or fob issued by the site or network | A phone with the app, an account and a data connection |
| Guests and one-off users | Easy — hand over a spare card; no account needed | Hard — the guest must install an app and register first |
| Starting a session | One tap at the reader | Open the app, find the charger, start from the account |
| When the connection is down | Cards on a locally held list can still be checked on the charger; platform-checked cards depend on the configuration | Starting from the app generally needs the phone and the platform to reach each other |
| Administration | Issue, record and revoke physical cards as people join and leave | Accounts are created and removed in the platform; no plastic to track |
| Accessibility | Works for drivers with no smartphone, no signal or a flat phone battery | Assumes a smartphone and enough digital confidence to use it |
The offline row deserves care, because it is where brochures overpromise. What a charger does when its platform link drops — checking a cached or local list, or refusing to start — is a matter of charger and platform configuration, stated in the platform’s documentation. Treat offline behaviour as a question to close when choosing the setup, not a property of RFID itself. Our guide to RFID and user management for shared chargers explains how local lists and platform control differ.
Where Each One Earns Its Place
RFID earns its place with known, repeat users and with anyone the app leaves out. Staff, fleet drivers and residents tap and go, a site can lend a visitor a card at reception, and the session still ties back to a named credential in the records. It is also the resilient option in underground car parks and rural sites where phone signal is poor — see our explainer on what an RFID card for EV charging is.
App control earns its place in reach and information. Drivers can find the charger, see live status and prices, and manage their own account without the site issuing anything. For a public-facing site that cannot hand out cards, the app — or a payment terminal, a separate purchase — is how an unknown driver starts. Our overview of how smart EV chargers work covers the account side.
Why Most Shared Sites Run Both
The two methods are not rivals so much as coverage for each other’s gaps, which is why shared sites commonly enable both on the same charger: cards for the regulars and the phone-free moments, the app for everyone else and for account self-service. EVDANCE builds that pattern into one unit — the EV-ACT3204PE 22 kW three-phase wallbox lists RFID and app control together, with a tethered Type 2 cable and an IP66 housing. For larger shared sites, the EV-AC03201T dual-connector station pairs RFID with OCPP 1.6J, so card lists and accounts sit on the operator’s platform for all chargers at once. See the wider range on our commercial charging page.
Frequently Asked Questions
Can a driver choose either method on the same charger?
Where both are fitted and enabled, yes — two doors into the same account system, with the session recorded against the driver’s credential either way. Which doors are open is the site’s platform configuration.
Which is cheaper to run, RFID or an app?
They cost in different places: cards have to be bought, issued and replaced, while app access rides on the platform service the site contracts for. Compare the card handling your site will actually do with the platform terms offered.
Which suits a workplace better?
For a set group of staff, cards are usually the simpler daily tool, and they cover visitors with a loaner. The app adds value where drivers need live status or the site wants account self-service.
