Square Reader device not working.

Below are some Square Reader device troubleshooting tips. 

Note: If you still have trouble, you can always take credit cards without a Square Reader by manually entering card information. 


All Readers

  • Make sure you're using a supported device.
  • Make sure all permissions have been given.
  • Turn off and then turn back on all permissions for the app.
  • Update the Trail's End app. 
  • Delete and reinstall the app on your device.


Bluetooth Reader

  • Temporarily disable Bluetooth from your device settings. 
  • Forget the Square Reader in the phone's Bluetooth settings, then restart the reader by holding the button for 10-15 seconds until the lights turn red. Then pair it in the Trails End app. 
  • Go to phone settings, and if the reader is listed there, forget it. If anyone at the site with you has paired it to their phone, have them do the same.


Plug In Reader

  • Check that the app has access to your device's microphone. This access allows your device to detect the reader. 
  • Remove your device's case, firmly plug in the reader, and swipe again. Some phone cases prevent the reader from plugging in all the way.
  • Check for lint or dust in your headset jack or Lightning connector. If you find debris, pull it out or blow carefully into the jack. 
  • Wipe the metal connector with a cloth. Residue can collect and prevent the reader from making a proper connection. 
  • Check for corrosion inside your headset jack or Lightning connector. If you see a green color, that's evidence of corrosion, and you may need to take your device in for service. 
  • Clear debris from the card reader slot with a card reader cleaning card or a paper towel.
