Square Magnetic stripe Reader Troubleshooting
If your Square Reader for magnetic stripe cards isn’t working properly, try the troubleshooting tips below:
Make sure you’re using a supported device.
Check that the Square 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.
With the Square app open, unplug the reader and firmly plug it back in.
Delete and reinstall the app on your device. See Apple support or Google support for instructions.
Temporarily disable Bluetooth from your device settings. Restore the bluetooth to accept payments with the Square Reader.
Check for lint or dust in your headset jack. 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. If you see a green colour, 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 cotton swab or a paper towel.
