Works offline
At a market, in a cellar, in the mountains. A QR payment needs no internet on your side.
Paying by QR code costs nothing.
Not you, not your customers. Payky turns your phone into a payment terminal: the customer scans a code and pays by bank transfer straight to your account. No fees, no contract, no hardware.

How it works
01
Type the amount
A keypad for quick sales, or a catalog of items and tables for a café. Whichever fits your business.
02
The customer scans and pays
The app shows a QR code for a bank transfer, in the Czech and Slovak formats. Cash and bitcoin are a tap away.
03
Money lands on your account
Straight from the customer's bank to yours. Nobody in between, no cut, no payout delays. Mark it received and you're done.
No contract. Your data is yours alone, and even we know nothing about you.
Built for merchants
Your data stays with you
Items, bills and history live on your phone or tablet. Backup and sync are optional and encrypted.
EET built in
Czech merchants report sales to EET 2.0 straight from the app, with retries whenever the network is down.
Cash too
Record cash sales beside the rest, so the day's takings are in one place.
Bitcoin, if you want
Lightning payments straight to your own wallet. Self-custody, and entirely optional.
Free and open source
No subscription, no cut of your sales. The code is public under the MIT license.
