Need Help on RFID Reader

Thank for your suggestion...
Now im able to make the rfid and lcd function as i want it,

But still have 1 more thing,
-How do i make the scan card/tag clear after a period of time with out clearing all the display??

#include <SoftwareSerial.h>
#include <LiquidCrystal.h>

#define rxPin 2
#define txPin 3

LiquidCrystal lcd(7, 8, 9, 10, 11, 12); 
SoftwareSerial RFID = SoftwareSerial(rxPin, txPin);
char code[20];
int val = 0;
int bytesread = 0;
int led = 13;

void setup()
{
  Serial.begin(9600); //open serial hardware
  RFID.begin(9600); //open serial software

  pinMode(rxPin, INPUT); //set pin on arduino for receiving RFID data
  pinMode(txPin, OUTPUT); //this is not important
  pinMode(led, OUTPUT);

  lcd.begin(16, 2);
  lcd.setCursor(0,0);
  lcd.print(" WELCOME TO JKE "); 
  lcd.setCursor(0,1);
  lcd.print("   KEY SYSTEM   ");  
  delay (5000);
  lcd.clear(); //Clears LCD
  lcd.setCursor(0,0);
  lcd.print(" TOUCH CARD/KEY ");
}

void loop()
{
  val = 0;
  bytesread = 0;

  while(bytesread < 12)
  {
    // read 12 digit code
    val = RFID.read();
    if(val == 3)
    {
      break; 
    }

    if(val != 2)
    {
      code[bytesread] = val; // add the digit
      bytesread++; // ready to read next digit
      code[bytesread] = '\0'; // add the NULL
    }
  }

  if(bytesread >= 12)
  { // if 12 digit read is complete
    Serial.print(" ");
    lcd.setCursor(0,1);
    lcd.print("  ");
    for(int i=0; i<bytesread; i++)
    {
      Serial.print(code[i]);
      lcd.print(code[i]);
    }
    digitalWrite(led, HIGH);
    delay(100);
    digitalWrite(led, LOW);
    delay(100);
    digitalWrite(led, HIGH);
    delay(100);
    digitalWrite(led, LOW);
  }
}

Please tesch or instruct me on how to do it... thanks...
