Contactless reader malfunction?

Saferideikweang — Sun, 21 Sep 2025 12:27:10 GMT

When I click charge, I get a little blue message saying “re-enable contactless”. I don’t see a green light come on and my reader won’t accept tap for interact/debit.

Hi @Saferideikweang

Sorry to hear about the trouble.

Have you tried a hard reset? Hold down the button on the front of the Contactless and Chip Card Reader until you see 4 flashing red lights. That usually does the trick for most issues.
