FAQs

What types of cash drawers are supported for HitPay POS ?

Can I connect the cash drawer without the HitPay printer?

he HitPay POS app does not directly support cash drawer control via the Android device. A HitPay Advanced Bluetooth Printer is required because it sends an electric pulse to trigger the drawer to open.
