arduino rfid help

hi

i am trying to make an rfid lock using the code below. where to i put the servo commands and how do i get it to move the servo when a certain card is detected?
thanks

int  val = 0; 
char code[10]; 
int bytesread = 0; 

void setup() { 

Serial.begin(2400); // RFID reader SOUT pin connected to Serial RX pin at 2400bps 
pinMode(2,OUTPUT);   // Set digital pin 2 as OUTPUT to connect it to the RFID /ENABLE pin 
digitalWrite(2, LOW);                  // Activate the RFID reader
}  


 void loop() { 

  if(Serial.available() > 0) {          // if data available from reader 
    if((val = Serial.read()) == 10) {   // check for header 
      bytesread = 0; 
      while(bytesread<10) {              // read 10 digit code 
        if( Serial.available() > 0) { 
          val = Serial.read(); 
          if((val == 10)||(val == 13)) { // if header or stop bytes before the 10 digit reading 
            break;                       // stop reading 
          } 
          code[bytesread] = val;         // add the digit           
          bytesread++;                   // ready to read next digit  
        } 
      } 
      if(bytesread == 10) {              // if 10 digit read is complete 
        Serial.print("TAG code is: ");   // possibly a good TAG 
        Serial.println(code);            // print the TAG code 
      } 
      bytesread = 0; 
      digitalWrite(2, HIGH);                  // deactivate the RFID reader for a moment so it will not flood
           delay(1500);                       // wait for a bit 
           digitalWrite(2, LOW);                  // Activate the RFID reader
    } 
  } 
}

You need to include the Servo.h file, at the top, and create an instance of the Servo class before setup(). In setup(), you need to attach the servo to a pin.

In loop(), after you read a card, you need to determine of the card is a good guy card or a bad guy card. Since the tags are strings, you need to create an array of strings, containing the good guy card tags, and loop through that array to see it the scanned tag is in the list. If so, write a new value to the servo.
