Trust Ingenico MOVE 5000 Contactless Troubleshooting
Have you attempted more than one card? This would confirm if the fault is with a particular customers card.
Otherwise whilst the terminal is on the main screen (Trust logo with 3 icons at the bottom), hold down the eye icon (above the red button on the keypad) and press restart.
If the same issue persists we need to check if the terminal is on the most up-to-date software. (Please note that a software update can only be carried out on Wi-Fi).
From the main menu press the icon with the dots in the bottom-right hand corner of the screen.

Select Admin

If an update is available this will download automatically and the terminal will reboot once complete. At this point try another 1p transaction.
