Possible Causes

Weak RFID antenna signal, Interference from a metal mounting surface, Slightly misaligned reader module, Aging RFID cards

How to Fix / Troubleshooting

Safety first: Turn off power before adjusting the reader module.

  • Test multiple cards: Try several RFID cards or tags to rule out a single weak card.
  • Card positioning: Hold the card flat and centered over the reader area for a few seconds.
  • Check mounting: If the charger is mounted on a metal surface, ensure there is the recommended spacing or insulating layer behind the RFID antenna area.
  • Inspect reader alignment: With power OFF, verify the RFID reader module is correctly positioned behind the front panel and not shifted.
  • If performance remains poor: Replace the RFID reader module or antenna assembly.
