Create a simple GUI for USB RFid Reader EM4100 using Raspberry Pi.

RFidEM4100GUI.py

from gpiozero import LED, Buzzer
from guizero import App, Box, Text, TextBox, warn
import csv

led8 = LED(19)

def clearDisplay():
    print("Clear display")
    rfidStatus.value = "---"
    rfidText.value = ""
    led8.off()
    rfidStatus.repeat(1000, checkRFidTag)

    tagId = rfidText.value
    if tagId != "":
        RFidRegistered = False
        print(tagId)
        with open("Database.csv") as csvfile:
            reader = csv.DictReader(csvfile)
            for row in reader:

Hi! Thanks for sharing it. Could you tell me wich python version are you using?

You can refer to this tutorial https://tutorial.cytron.io/2019/07/25/create-a-simple-gui-for-usb-rfid-reader-em4100-using-raspberry-pi/. The video is in the Malay language, but there have English subs. Hope this helps.

@IdrisCytron Nice! Thanks for answering! 😁
