How do I read the PAN from an EMV SmartCard from Java

Question

I need to read account number from Maestro/Mastercard with smart card reader. I am using Java 1.6 and its javax.smartcardio package. I need to send APDU command which will a

Answer 1

here is some working example:

CardChannel channel = card.getBasicChannel(); 

 byte[] selectMaestro={(byte)0x00, (byte)0xA4,(byte)0x04,(byte)0x00 ,(byte)0x07 ,(byte)0xA0 ,(byte)0x00 ,(byte)0x00 ,(byte)0x00 ,(byte)0x04 ,(byte)0x30 ,(byte)0x60 ,(byte)0x00};
  byte[] getProcessingOptions={(byte)0x80,(byte)0xA8,(byte)0x00,(byte)0x00,(byte)0x02,(byte)0x83,(byte)0x00,(byte)0x00};
  byte[] readRecord={(byte)0x00,(byte)0xB2,(byte)0x02,(byte)0x0C,(byte)0x00};

  ResponseAPDU r=null;

   try {
     ATR atr = card.getATR(); //reset kartice

      CommandAPDU capdu=new CommandAPDU( selectMaestro   );

       r=card.getBasicChannel().transmit( capdu );

      capdu=new CommandAPDU(getProcessingOptions);
      r=card.getBasicChannel().transmit( capdu );


      capdu=new CommandAPDU(readRecord);
      r=card.getBasicChannel().transmit( capdu );

This works with Maestro card, I can read PAN number, yet now I need to read MasterCard's PAN number. I do not know should I change the read record APDU or select application APDU. Anyone familiar with APDUs?
