Question 1

Is an RFID card for EV charging the same as a payment card?

Accepted Answer

No. It carries an identifier the charger sends to the backend for an allow-or-refuse decision. Money moves afterwards, through whatever the account is linked to.

Question 2

Can drivers charge if the charger loses connectivity?

Accepted Answer

Only if it is set to authorise offline and actually stores a local list or cache — both optional in OCPP. Accepting unknown tokens is a separate setting.

Question 3

How quickly can a lost charging card be revoked?

Accepted Answer

Instantly for online stations. Offline-capable chargers honour it until the local list updates or the cached entry expires — your sync interval plus that expiry.

Question 4

Can our charging cards be cloned?

Accepted Answer

If the reader authenticates on the identifier alone, assume yes. Cap per-token energy and spend, alarm on one token charging in two places, and move closed sites to challenge-response cards.
