Logic Sniffer: Hacking cheap RFID readers

Aaron decided to hack a cheap USB RFID reader, by using the Logic Sniffer to figure out the internal IC protocol.

To make it useful for his projects he decided to hijack the internal bus that has the initial RFID decoding. After some poking around he was able to find the UART TX transmitting pin. By using his Logic Sniffer he successfully decoded the signals sent internally between ICs and is now free to use his new toy in any way he likes.

  1. Where can I find more about this? I’m planning on using RFID on my new project and this would be helpful.
