Wiring For The Raspberry Pi And RFID:

SDA To Pin 24
SCK To Pin 23
MOSI To Pin 19
MISO To Pin 21
GND To Pin 6
RST To Pin 22
3.3v To Pin 1

sudo raspi-config  "Enable SPI Setting And Reboot"

sudo apt update
sudo apt upgrade

sudo apt install git python3-dev python3-pip
sudo pip3 install spidev
sudo pip3 install mfrc522
--------------------------------------------------
mkdir rfid
cd rfid
sudo nano write.py   "Paste The Following And Save File"

#!/usr/bin/env python

import RPi.GPIO as GPIO
from mfrc522 import SimpleMFRC522

reader = SimpleMFRC522()

try:
        text = input('New data:')
        print("Now place your tag to write")
        reader.write(text)
        print("Written")
finally:
        GPIO.cleanup()

-----------------------------------------------------------
sudo python3 write.py  "To Run The write.py Script" "Give New Data A Name"
-----------------------------------------------------------
cd rfid
sudo nano read.py  "Paste The Following And Save"
-----------------------------------------------------------
#!/usr/bin/env python

import RPi.GPIO as GPIO
from mfrc522 import SimpleMFRC522

reader = SimpleMFRC522()

try:
        id, text = reader.read()
        print(id)
        print(text)
finally:
        GPIO.cleanup()

-----------------------------------------------------------
Now It Should Print Out The New Data ID
