I have managed to build an access system for standard fully automatic coffee machines. Coffee cannot be purchased without the right RFID chip.
In addition, it is planned to implement a billing function so that the machine can be used in the office, for example.
The basis is a Teensy 3.5 as well as two self-made PCB layouts.
In the next weeks I will create a Github project for all those who are interested in the project or want to rebuild it and post the link here.
