> Good background on "Loyality Cards" and Rob's workaround:
>
>         Carlson had the flash of inspiration to
>         set up Rob's Giant Bonus Card Swap Meet
>         (http://epistolary. org/rob/bonuscard).
>
>         Carlson's site works like this: You enter your Giant
>         card number on a form. It puts this number into a pool
>         of numbers gathered from participants. Drawing from this
>         pool, it displays for each visitor a bar-code replica of
>         someone else's number, allowing the visitor to print it
>         out and tape onto his or her own card. Should you actually
>         take the time to do this and then visit the local Giant
>         to use this card, you are, to Giant, someone else. If
>         enough people do this, the argument goes, Giant's shopper
>         profiles are rendered muddied and ultimately useless.
>
> as well as a look ahead at RFID.
