INTRODUCTION:
MOD-RFID125 is an RFID station, able to read Manchester-encoded 64-bit
EM4102 tags with 64 periods of carrier frequency per data bit. All the
complexity of RFID tag detection, verification and decoding are handled by
MOD-RFID125. After it strips the header and the checksums user is given
the 40-bit ID of the transponder tag.
MOD-RFID125 supports three distinctive modes of operation, easily
switched by a single button press. It can emulate USB HID keyboard and
input the read TAG ID directly to any Windows application, including the
venerable Notepad. Or it can emulate USB CDC serial port for easy access
from custom user applications using standard code for COM port access.
The third option allows access from any standard 5V UART, allowing easy
integration with existing microcontroller applications.
