"Bugged" calling cards?

The way calling cards in the US work is that the user calls an 800 number and then enters a PIN number and the number to be called. The way 800 numbers work, the 800 number operator (ie, the company that pays for it) gets a list of all the numbers that dialed it, because he's paying. It seems that it should be possible to create a "bugged" calling card. You give this to someone as a "free prize" or whatever and then you get a list of all the numbers he calls to and from using it. Does anyone know if something like this exists, which I can buy? I want to send someone a "present". Thanks
