Merchant generates QR-code in the application or places a sticker with it on any medium. The buyer scans QR-code with smartphone’s photo-camera or application (Chrome, Tachcard, QR-reader) and pays with any card. It is convenient for fast payments.
The buyer simply brings his contactless card close to the merchant’s android-smartphone. It is convenient, for example, to accept payment, if you have queue.
It is enough to bring smartphones with the application to each other. Convenient for individual cases. For example, for the interaction of a smartphone and a vending machine (instead of a second smartphone).
