About the project Monyx Wallet (product page) is Nayax's mobile wallet for automated businesses: vending machines, laundromats, car washes and other self-service devices. Users pick a device by number or address, or scan a QR code, and pay from their phone. The app supports prepaid cards for closed-loop systems, promotions and loyalty programs, automatic refunds, branded cards, and an SDK for integration into operators' apps. Where the project is now. A significant part of Monyx has already been rewritten in Flutter as a standalone plugin with its own repositories. Next, a new standalone Monyx app will be built on top of it in Flutter. Some of the logic still needs to be covered,
