This is a paper about basic RFID security issues but with focus on the MIFARE Classic technology. It was part of my university studies (fourth semester). As part of this research, I had a closer look at the MIFARE Classic-based system of my university. Because of the multiple use cases (payment, access control, amount of free copies at the printers, etc.) there are plenty of attack vectors. Furthermore, I build an RFID zapper. This device can destroy RFID chips without leaving a trace (visible from the outside).
