Have you ever need to send a bank account number to your friend? Have you ever order a food together with a colleague, and he wanted to give your money back by bank transfer?Now it is easy. You can generate the QR code with your transaction details (same as you can sometimes find on the invoice for telephone or Internet). Most of the Polish banks apps will understand the code and will fill your name, 26 digit IBAN number, transfer title and amount automatically. So nobody will say: I do not have time to do the bank transfer now. 26 digits, its to hard to input. I do not know your bank account number.Now you generate the 2D bar code and all they need to do is to "snap it" in their bank app. Its simple and easy.
