Your PAX POS machines run Android AndroidPay OS. Most of the icons and menu features on the PAX are standard Android icons and features. LOU POS is the LOU app you run on the PAX. We’re going to take a quick look at some of the Android OS functions of PAX.
If you are familiar with Android, you should be familiar with the buttons and system icons used by PAX.
IMPORTANT! The AndroidPay OS is not LOU software. We cannot control changes to the OS. For more details on how to navigate AndroidPay OS, see AndroidPay resources here.
