PAX A800 Smart POS Terminal

Elegance at the counter and flexibility beyond it!

A Smarter Countertop Experience, Built On Android

The PAX A800 is a touch-screen desktop payment solution that blends Android technology with secure payment acceptance in a single device. It’s designed to help merchants streamline checkout and unlock value-added capabilities (like loyalty and in-store product tools) through supported applications and services.

Take fast, secure in-person payments on a 5.7” Android touchscreen, built for chip & PIN, contactless NFC, and magstripe transactions. It comes with optional cameras for barcode/QR scanning and an optional battery for in-store portability.

This terminal option is a great option for supermarkets, fashion & retail, and food & beverage businesses that want a modern SmartPOS experience at the counter (with the option to go portable when configured with a battery).
