Time Turner - Hacking RF Attendance Systems (To Be in Two Places at Once)

Presented at DEF CON 29 (2021), Aug. 7, 2021, noon (20 minutes).

It's a tale as old as time: a graduating senior needs two more courses to graduate, but the lectures happen to be scheduled at the same time and the school's new high-tech wireless attendance tracking system makes it impossible to attend both courses... in theory. By reverse-engineering the attendance devices and emulating them using a hidden Arduino, the system can be tricked into giving attendance credit for both courses without being physically present. It's a real-life "time turner," allowing him to be in two places at once.
