I got a Smart Card reader out of a laptop. There's not much going on on the board, just the card receptacle on one side, with the contact springs, and two ICs on the back side:
A Cypress CY7C63001 A-SC USB micro controller, which is the bigger of the two, and finding datasheets for that is no problem.
Now the chip that interfaces the Smart Card chip, is a Texas Instruments 36A2DKK (2nd line: HC02), no datecode. It's a 14 pin SOIC-150 package.
I can't really show you a picture, I don't have any camera or macro lenses, that would make a decent photo of the markings.
I checked the usual places for datasheets, and manufacturers websites, but I can't find a single thing about it. The datecode on the micro controller is 0406, 4th week of 2006 would make sense.

It's a SN/CD54/74HC02 quad NOR. The "36A2DKK" is a lot code.
