The short answer: an Android POS system is point-of-sale software that runs on an Android phone or tablet, turning a device you may already own into a full till — scanning items, taking payment and printing receipts. It’s a low-cost, flexible way to run a shop, a market stall or a mobile business.

How an Android POS works

You install the POS app on an Android device. The phone’s camera (or a small scanner) reads barcodes, the app totals the sale and records payment, and a compact Bluetooth, USB or network printer produces the receipt. Dedicated Android POS terminals — like Sunmi devices — build the printer and scanner into one handheld unit.

Why Android POS suits small and mobile businesses

What to look for

  1. Works with common printers (Bluetooth/USB/network) and Sunmi terminals.
  2. Offline selling so a weak signal never stops a sale — see offline POS.
  3. Connected to inventory and accounting, not a standalone app.
  4. Role controls so cashiers only see what they need.

Run it on hardware you already have

RushFlow includes a native Android POS app (with Sunmi and printer support) built into full inventory and accounting — so a sale on the phone updates stock and your books automatically. Explore the live demo, or read what is a POS system.
