@boilingsteam @ozoned @martin In Poland, we have BLIK since 2015. Similiar principles, no visa/mastercard required. From wikipedia:
"Transactions are uniquely identified by 6-digit one-time codes, each time valid for up to 2 minutes, which the user obtains using their mobile banking app. The code can then be typed in online, entered on the ATM screen, or on compatible contactless payment terminals. The payment requires final authentification of the vendor and transaction amount in the app and is instantaneous.
Blik allows instant transfers between users by binding phone numbers to bank accounts.[16] These transfers are similarly free and instantaneous, even between accounts from different banks. Some online shopping platforms, like Allegro, are able to connect a customer account to a Blik-compatible app instance allowing for payment confirmation with just a notification prompt and pin code or biometric login."
