You can hide payment types on the till itself by ging to file -> configuration -> paymenttypes
Click on “auto” for the desired payment type and choose “hidden”, close the screen by clicking OK.
(auto is the default value, this way the payment type is shown if the payment type is not cancelled backoffice)
This can be done on all tills individually. After changing a restart of the till is necessary to make the changes go in effect.
This way it also possible to show a specific payment type only on one till. To do this the payment type can be set to cancelled backoffice.
On the till the payment type can be set to “visible”
If you want to hide a payment type completely on all tills, the payment type can be marked as cancelled in the backoffice by
going to administration -> payment types open the desired payment type and mark it as cancelled.
