Safety first: Turn off power before accessing internal modules.

Test multiple cards: Try more than one known-good RFID card or fob to rule out a bad credential.
Inspect reader area: Check the front panel over the RFID symbol for cracks or impact damage.
Check RFID module connection: Inside the unit, verify that the RFID module is securely connected to the control or display board.
Replace RFID module: If connections are good and the feature is enabled in configuration, replace the RFID reader module.

Charger’s RFID reader (if equipped) does not recognize cards or fobs.
