UHF RFID Reader and Python

Question

I‘m looking for a UHF RFID Reader, that can be easily controlled with a raspberry pi and a python3 library. I could only find readers that were for arduino or serial.

Answer 1

Mostly all RFID readers work on serial communication. So you can easily use any serial port python library to connect to RFID module and get the RFID tag id. This will work on any type of machine i.e. windows, linux or raspberry pi.

For ex, follow below code:

import serial

rfid_serial_port = serial.Serial("/dev/ttyUSB0", 9600)

id_num = []
i = 0
while True:
    serial_data = self.rfid_serial_port.read()
    data = serial_data.decode('utf-8')
    i = i + 1
    if i == 12:
        i = 0
        ID = "".join(map(str, id_num))
        print(ID)
    else:
        id_num.append(data)

Or you can use pyembedded python library

pip install pyembedded

from pyembedded.rfid_module.rfid import RFID
rfid = RFID(port='/dev/ttyUSB0', baud_rate=9600)
print(rfid.get_id())
