Ways to authorize a session
| Method | How it works |
|---|---|
| RFID / app token | Driver taps their personal token at the charger. |
| Roaming token | Driver’s eMSP authorizes the session via OCPI. |
| QR code / ad-hoc | Pay-as-you-go without an account. |
| Plug & Charge | ISO 15118 certificate exchange (where supported). |
Optimizing for drivers
- Keep EVSE status accurate — drivers route based on real-time availability.
- Publish clear tariffs — surprise fees damage trust.
- Make idle fees visible before the session starts.
