An Interrupted Error refers to the connection either to the internet, or to the card reader itself being lost.
To fix, make sure the tablet has a good internet connection and that the card reader is connected properly. You will know the card reader is connected properly when you see the earphone symbol at the top.
Once an Interrupted Error happens, the driver may need to reboot the tablet and try the payment process again
If neither of these are the case, please submit a ticket and IT will contact you asap to resolve the issue.
