copy the code and must change the UID code or HEX code....
use use tag UID code...

this video is my 100th video in youtube to get my app click here before uploading change the uid code of the your RFID tag... then upload that code coding for that video  /* PINOUT: RC522 MODULE    Uno/Nano     MEGA SDA             D10          D9 SCK             D13          D52 MOSI            D11          D51 MISO            D12          D50 IRQ             N/A          N/A GND             GND          GND RST             D9           D8 3.3V            3.3V      ...
