Payments through the mobile at the point of sale of Privatbank

Privatbank apparently inspired by Flattr startup ( http://flattr.com ) decided to quickly make an alternative service at home, positioning it as a replacement for POS terminals. The seller sends a specific format with the payer's phone number to the service number 7440, while the payer sends an SMS to the same number 7440 with his card number + validity period + cvv2. All operations go through https://www.liqpay.com. In general, here is a picture explaining the essence:
In general, the idea is interesting, and I think as soon as it can be run in, it will be possible to use it. In the meantime, everything is too damp and too many questions. Details in the blog .
