How can I write personal data on a RFID sensor in arduino in my code?

[marius_2004]

I want to write a personal data on my card introduced in this code like:
"Name"

"Age"

"Region"

And then i put the card on the sensor i want to appear like this:

Authorized access

Name: Marius

Region: EU

Age: 30

#include <SPI.h>

Servo myServo; //define servo name
 
void setup()

  SPI.begin();      // Initiate  SPI bus
