How RFID-Based EV Charging Works
Learn how RFID identifiers authorize EV charging sessions and how operators should manage access.
Published October 30, 2026RFID is an identifier
An RFID card or tag presents an identifier to the charger. The charger sends an authorization request to the CSMS, which checks whether the identifier is permitted before the session starts.
Lifecycle management
Operators need processes to issue, activate, suspend and replace identifiers, associate them with accounts where appropriate and review their charging history. Lost tags should be disabled quickly.
Offline and security behavior
Some chargers can cache authorization data for temporary offline operation. Cache rules, identifier privacy and transaction reconciliation should be tested for the selected charger model.
