This project combines my remix of a slim 3D printable wallet with a circuit that emulates RFID tags. The RFID tag circuit uses a coin cell battery for power and has buttons which trigger different RFID tags to be transmitted.

The schematic for the RFID PCB. This is based on an ATTiny85
I have combined all the PCB and source code files into one repository found here on Github.
Circuits generally have a fair amount of vertical height to them so I have had to think of ways to reduce the height so that it does not increase the overall height of the circuit board.
I am busy making the PCB at home and waiting for some of the components before I can test out this design.
