This project offers full control over fully-automated coffeemakers. I made a payment system which uses common RFID tags. The tag number and the remaining credit is displayed on a LCD whenever a tag will be read and (and has been registerd before). An app for the 'coffee admin' allows registering, charging and deleting of RFID cards.
Thank you for providing information about the Coffeemaker Payment System with toptronic logic unit integration for Jura coffeemakers. It's great to know that the payment system has already been set up.
If you have any questions or need further information about subscription payments or how the payment system (https://www.subscriptionflow.com) operates, please feel free to ask. I'm here to assist you with any additional details or inquiries you may have.
