Smart card security: Disable a lost smart card and track with GPS?

I have reason to believe one of our enterprise's employees sold a smart card to someone outside the company. We've disabled the smart card so it can no longer be used, but is there any way to track a lost smart card?

Unless you have the unlikely capability of coupling your smart card with a GSM chip or signal transmitter for use with the Global Positioning System (GPS) satellite network -- which is possible if you are using a mobile two-factor authentication scheme, I'm afraid there's really no way to track it down.

Assuming you've developed and distributed a corporate policy concerning the appropriate use of smart cards and/or other access devices to support your actions should this become a legal matter, you should have disabled the smart card, which is the reasonably expected action.
