Create A Simple GUI For USB RFid Reader EM4100 Using Raspberry Pi

Introduction

Today I would like to try to interface 125KHz USB RFID Smart Card Reader EM4100. Since it is using USB cable, I choose Raspberry Pi as a controller. Even it is using USB, it is not require a driver to interact with computer. You can open any text editor, once the reader detects tag, it will read and display the tag ID to the text editor. But, how if you want to put it in the program? Let's try!
