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.
• Make sure the "access nearby devices " permission for the Trail's End app is on/allowed

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 headphone jack. USB-C, 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 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.
