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

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>
#include <MFRC522.h>
#include <Servo.h>
 
#define SS_PIN 10

#define LED_R 5 //define red LED
#define BUZZER 2 //buzzer pin
MFRC522 mfrc522(SS_PIN, RST_PIN);   // Create MFRC522 instance.
Servo myServo; //define servo name
 
void setup() 
{
  Serial.begin(9600);   // Initiate a serial communication
  SPI.begin();      // Initiate  SPI bus
  mfrc522.PCD_Init();   // Initiate MFRC522
  myServo.attach(3); //servo pin
  myServo.write(0); //servo start position

  pinMode(LED_R, OUTPUT);
