Payment via Cash Card / Credit Card (CCV)
When adding "Cash Card (CCV)" or "Credit Card (CCV)" payments, simply edit the amount to be paid. By default, the field is prefilled with the Downpayment amount or the total remaining amount to pay.

After changing the amount, make sure to click or press the "Cash Card" or "Credit Card" button. At that point the CCV Cash Card Payment Device is contacted. The Point of Sale application will wait for a response from the terminal for a limited amount of time.
In case of an error, the response message from the terminal will be displayed in this window.
Card Payments can NOT be changed or removed after a successful message from the terminal.
