[Karimullah Syed]

Dear All,

String emvData="84667DD7C0F1F32A02606588789A57A7A9EEE1583544CB8A6B140D071924D35D949ED5ED7A54B69A84667DD7C0F1F32A02606588789A57A7A9EEE1583544CB8A0723DB6DF0FCE6CF0000000000000000";

I need to parse the above emv data which come from the terminal (ingenico,verifone) in DE 55 to my jpos application,

How do i parse the EMV tags Tag length Value,how to print the tag values with the above emv data in the java example.

Appreciated, if some one shares the snippet of java code for parse the emv data.looking for the java snippet code.it will really help me a lot.

Thanks

Karimullah Syed.

This ICC data seems weird (is it truncated?), but you can use code like this:

import org.jpos.iso.*;
import org.jpos.tlv.*;

byte[] emvData = ISOUtil.hex2byte("84667DD7C0F1F32A02606588789A57A7A9EEE1583544CB8A6B140D071924D35D949ED5ED7A54B69A84667DD7C0F1F32A02606588789A57A7A9EEE1583544CB8A0723DB6DF0FCE6CF0000000000000000");

TLVList tlv = new TLVList();
tlv.unpack (emvData);
tlv.dump (System.out, "");

It seems you have tag 08 and F0 there.

When I execute the code above with a different ICC data, it outputs the xml below, is that what is referred to as TLV format ?

If it is the TLV format, how do I retrieve into a variable and how can I pass it to a field 55 in an ISO message ?

<tlvlist>
   <tag id='9f26' value='5C2B1447476C64A7' />
   <tag id='9f27' value='80' />
   <tag id='9f10' value='0110A080002A0000C32700000000000000FF' />
   <tag id='9f37' value='56B7BFA0' />
   <tag id='9f36' value='1080' />
   <tag id='95' value='0080248800' />
   <tag id='9a' value='220704' />
   <tag id='9c' value='00' />
   <tag id='9f02' value='000000002000' />
   <tag id='5f2a' value='0566' />
   <tag id='82' value='3800' />
   <tag id='9f1a' value='0566' />
   <tag id='9f34' value='420300' />
   <tag id='9f33' value='E0F8C8' />
   <tag id='9f35' value='22' />

   <tag id='84' value='A0000000041010' />

You call m.set(55, tlv.pack());
