Open RFID Tag - EM4100 cloner firmware
How the EM4100 cloner works.
Pressing button S1 when approaching the Open RFID tag to a RFID reader will boot the capture mode.
In this mode, the Open RFID Tag sniffs and decodes the communication between the RFID tag and the RFID reader. If an EM4100 memory map is correctly captured (the CRC and parity is checked), the memory map is stored and LED1 is switched on.
If S1 is not pressed, the Open RFID Tag emulates the latest RFID tag captured.
100% passive. No battery.

The simplest possible RFID emulator
This is the simplest possible RFID emulator.
It only uses a PIC 12F microcontroller and a 10 mH axial inductor.
The firmware loaded emulates a EM4100 tag.
