pyrfidhid

Python library to control Chinese USB HID 125Khz RFID Reader/Writer

Introduction

This library is the result of reverse-engineering the communication protocol of a Chinese USB 125Khz RFID Reader/Writer. A detailed document describing the whole procedure can be found at the wiki section of this project:

How to reverse engineer a USB HID RFID Reader/Writer

The library can be used to control the USB RFID device under Linux or MacOS, and it uses pyusb and libusb to communicate through the USB port.

Installation (using pip)

You will need Python 2.7.x or greater, and pip.

MacOS

$ brew install libusb
$ pip install pyusb
$ pip install --upgrade pyrfidhid

Linux

$ sudo apt-get install libusb-1.0-0-dev
$ sudo pip install pyusb
$ sudo pip install --upgrade pyrfidhid

Manual Installation

If you can't install the library using pip, then try to install it using setup.py script. Just clone this repo, install the dependencies and run the setup.py script:

$ python setup.py install

Usage

The library should work with both Python 2.7.x and 3.x. After running the setup.py script you should be able to import and use the library within your project like this:

from rfidhid.core import RfidHid

try:
    # Try to open RFID device using default vid:pid (ffff:0035)
    rfid = RfidHid()
except Exception as e:
    print(e)
    exit()

payload_response = rfid.read_tag()
uid = payload_response.get_tag_uid()

rfid.beep()
print(uid)

The above script should try to connect to the device, read a Tag (if it is already close to the device), print the UID and beep.

For more complex read/write examples, please check out the examples folder.

You can also check the API documentation for a list of exported methods.

RFID CLI Tool

A command line tool called rfid_cli is also included with the library, and it can be used to read, write and clone tags. For a complete documentation please check rfid_cli documentation
