Time Turner: Hacking RF Attendance Systems To Be in Two Places at Once

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. PUBLICATION PERMISSIONS:
