Warning

If merchant app disables the navigation bar, they will need to implement a mechanism to activate it temporary. Otherwise, the POS will be blocked in case there is a manual intervention that needs to be done on the POS Device.

The variable to desactivate the Nav Bar via SUNMI will be shared between merchant app and payXpress app.
By Default, PayXpress app deployed in the P2 LITE SE / P2 PRO devices will activate the Nav Bar in the standbyscreen (initial screen) and then it will disable it during the payment transaction. Once the payment has been finalize it will be activated it back automatically.
