Updated March 2026

Share

This is general guidance based on the ChargeX MREC standard. Actual charger behavior varies by manufacturer and firmware version. Always follow on-screen instructions and contact the charging network if you are unsure.

Warning

The Kempower charger could not verify your payment or RFID card. This may be a network connectivity issue, an unsupported payment method, or an expired subscription.

What to do

  1. Try tapping your RFID card or payment card again. Hold it steady for 2 to 3 seconds
  2. Use the network's app to start the session instead
  3. Check if your account has a valid payment method on file
  4. Try a contactless bank card if your RFID card is not working
  5. If all methods fail, try a different charger or network

Who's responsible?

  • This may be something you can fix yourself
  • The charging network operator needs to fix this
