Security Card Reader

Arduino-based card reader for decoding HID security cards used at my university.

About

A simple card reader that was hooked up to an Arduino to read the raw binary output of an RFID/HID card. My university (University of Nevada Reno) used HID security access cards which are harder to decode/clone than traditional RFID cards and I wanted to find a way to decode my card. Decoding the card could allow me to possibly replicate my card or find various ways to increase security at the university. Different card readers can only read certain cards and formats. The card reader I used was a Software House SWH 5100 Multi-Format Proximity Reader since it was the most similar one at my university and could read my card.
