125Khz RFID library for Arduino. 

This library only support TTL RS232 serial port.

![125Khz RFID Reader][RFID Image]

When read the data from some RFID card, you will get data like `00 91 6f 0b f5`.

Example:
```
your card number: 0009531147
that your data  : 00 91 6f 0b f5
```
**Notice, f5 is the check bit**

`f5 = 00^91^6f^0b`


#### Pins 

1. VCC support 3.3 ~ 5V
2. TX, RX connect to Arduino or Seeeduino
3. T1, T2 is the Signal port for RFID antenna
4. W0, W1 is for wiegand protocol, but this library not support yet.
