RFID cards are not recognized; charger stays locked even though RFID mode is enabled.

Safety first: Isolate power before adjusting the reader.

• Test at close range: Hold the RFID card directly against the marked reader area for several seconds.
• Remove interference: Ensure there are no metal plates, stickers with metallic ink, or other objects covering the reader area.
• Reposition reader: Inside the charger, adjust the RFID reader board so it sits flush and centered behind the front panel.
• Reboot charger: Power cycle the unit to clear any temporary reader faults.
• Replace reader: If cards still are not recognized, replace the RFID reader module.
