Contact-less card through an OmniKey, how to get "UID"?

Question

I am trying to read information off of a smartcard, using a contact-less OmniKey 5321 card reader.

Edit: Added a bounty.

I'm writing a C# 3 in .NET 3.5 program, so this is a Windows application.

The card has some information stamped onto it, that I would assume, in some way, is present in the card data (there is a photo of the card and reader below.)

The card has the following information stamped onto it:

1* 00447   21091328-32

When using the Diagnostics application that comes with the OmniKey card reader, I get the following information:

Smart Card Name: iCLASS 16KS UID:EE 74 0E 00 FB FF 12 E0
ATR            : 3B 8F 80 01 80 4F 0C A0 00 00 03 06 0A 00 1A 00 00 00 00 78
Protocol       : ISO 15693 (Part 2)

Now, here's some conversions I've considered:

• 447 decimal = 1BF hexadecimal (not found)
• 447 octal = 295 decimal (not found as BCD-type encoding)
• 447 octal = 127 hexadecimal (not found)
• 447 hexadecimal is not found

Here's my questions:

• Is the "UID" number a unique number that I can rely on? I don't really care about the 447 number, all I need to know is that the information I pick from this card will uniquely identify it later, so that I can link it to the owner of the card
• How would I go about reading the UID number? Using WINSCARD.DLL in Windows I can see that I get the "ATR" data, every single byte, but the UID is apparently not present in that part.

Here's the photo, if that gives you any information.

Answer 1

You can rely on UID but it seems truncated in your case :

UID:EE 74 0E 00 FB FF 12 E0

Uid are usually 16 bytes long.

You can read this Unique Identifier (UID): All ISO-compliant smart cards are provided with a UID number (akin to a VIN number on a vehicle). For interoperability purposes, a card’s UID is open and available to be read by all compliant readers. Since this unique number is not secured by keys, reading the UID of a smart card is comparable to reading a proximity card, mag stripe card or other technology that utilizes open, unsecured numbers.
