RFID Payment Systems - free drinks and all you can eat

I’ve did a presentation at the “Gulaschprogrammiernacht” in Karlsruhe. This talk was about RFID/NFC-based payment systems that are often seen in university menses or company canteens. You typically pay with the student ID card or you employee badge, which is preloaded with money or linked to you monthly salary.

The security of some of these systems is severely broken due to the usage of old and insecure RFID/NFC technologies. The talk contains some basics about those insecure RFID/NFC technologies and stories of broken systems I’ve analyzed in the past.
