RFID cards that used to work are no longer recognized; charger stays locked.

Note: This is often a configuration or backend issue rather than hardware failure.

• Check app/portal: Confirm that the RFID cards are still listed as authorized in the EVBox portal or app.
• Resync: Force a sync with the backend by ensuring the charger is online and waiting several minutes.
• Test close range: Hold the card directly against the RFID reader area for several seconds to rule out weak signal.
• Try another card: Use a different known‑good card to determine if the issue is card‑specific.
• If no cards work and configuration is correct: The RFID reader module or antenna may be failing and should be replaced.
