How do I troubleshoot a #505 error on my Toast Go® 2?
Answer
If you're seeing a #505 error on your Toast Go® 2, follow these troubleshooting steps:
Restart your Toast Go® 2 by pressing and holding the power button until the Power Off option appears, then tap it to power off the device.
Then, go to the Quick Order screen and select the Tab to wake up the reader. At this point, the card indicator light on the side of the device should be green. If it's red or no light appears, follow the steps below to check the card reader with the test app. Before doing so, if dip and tap payments are not working but swipe payments are accepted by your card reader, double-check that EMV is enabled on your device. For a refresher on setting up EMV for the Toast Go® 2, check out this Support Center article,
Use the Card Reader Test App
Select the circular Home button at the bottom of your device screen.
Then, select CardReader Test App.

If you see Result: Fail, contact and reference code #505.
If you see Result: Pass, perform the following steps:
Exit the Reader Test App.
Go to Settings > Apps & notifications > Toast POS > Advanced > Open by default > Clear defaults.
Turn off your device, then turn it back on.
