Adding multiple cards to a RFID reader.

Can you help me. How can i define an 2. card?
My code:

#include <SPI.h>
#include <MFRC522.h>
#include <Servo.h>

int RST_PIN = 9;
int SS_PIN = 10;
int servoPin = 8;

Servo motor;
MFRC522 rfid(SS_PIN, RST_PIN);
byte ID[4] = {102, 195, 14, 255};

void setup() {
motor.attach(servoPin);
Serial.begin(9600);
SPI.begin();
rfid.PCD_Init();
}

void loop() {

if ( ! rfid.PICC_IsNewCardPresent())
return;

if ( ! rfid.PICC_ReadCardSerial())
return;

if (rfid.uid.uidByte[0] == ID[0] &&
rfid.uid.uidByte[1] == ID[1] &&
rfid.uid.uidByte[2] == ID[2] &&
rfid.uid.uidByte[3] == ID[3] ) {
Serial.println(“Kapi acildi”);
ekranaYazdir();
motor.write(180);
delay(3000);
motor.write(0);
delay(1000);
}
else{
Serial.println(“Yetkisiz Kart”);
ekranaYazdir();
}
rfid.PICC_HaltA();
}
void ekranaYazdir(){
Serial.print(“ID Numarasi: “);
for(int sayac = 0; sayac < 4; sayac++){
Serial.print(rfid.uid.uidByte[sayac]);
Serial.print(” “);
}
Serial.println(””);
}

if (rfid.uid.uidByte[0] == ID[0] &&
rfid.uid.uidByte[1] == ID[1] &&
rfid.uid.uidByte[2] == ID[2] &&
rfid.uid.uidByte[3] == ID[3] ) {}
just add this one more time whit youre new address
