Why a phone is enough

A dedicated POS terminal is one more thing to buy, charge, and eventually replace. Most small shops already have an Android phone behind the counter. Kaynko POS is built to make that phone do the job of a full point-of-sale system, without a separate device.

Billing in seconds

Search or scan a product, apply a discount if needed, take payment. Checkout is designed to complete in under 10 seconds.

Camera barcode scanning

Scan a barcode with the phone's own camera — no separate scanner required. A Bluetooth barcode scanner also works, for shops that want one.

Bluetooth receipt printing

Pair a Bluetooth thermal printer once; it reconnects automatically every time you open the app.

Works without internet

All sales and stock data live on the phone itself. A dropped connection never stops a sale.

Set up in minutes

  1. Install Kaynko POS from Google Play.
  2. Add your business name, a few products, and prices.
  3. Open a cash session and start selling.

No training, no setup call, and no technical knowledge needed to get a first sale done.

Try it on your own phone

Free for 14 days, no credit card required.
