Possible Causes
Weak RFID antenna signal, Interference from 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.
