MiniPOS APQT / PrintPOS APW3 - 'Restricted card' error

When you get a restricted card error, it normally means the cardholder must contact their bank to find out what the issue is.

In many cases, this error can be resolved by inserting a card if you tapped it the first time.

You can also try to go to the device settings > apps and permissions > cashier app > storage > clear data & clear cache (bank your car machine first)
