Different values of different RFID readers

Question

I have two different RFID readers which both give different outputs. One RFID readers is this one from dealextreme: http://dx.com/p/intelligent-id-card-usb-reader-174455 It is plug and play. Of the other reader I only have the program which we use to generate the code which is HidIdMonitor.exe

The first one generates the following code: 0221365003

The second one generates the following code: 010d31c30b

The problem is that I cannot find any form to convert one code to the other. Is there anyone who can tell me how to convert this, or what the code is based on.

Answer 1

Is the same value. Hex and Decimal!!

 0221365003 = decimal
 D31C30B = hex (010 is a prefix)
