cardA company called Vivotech is using the the fact that people don't enjoy carrying a bunch of different customer loyalty cards (or keychain dongles) to push an even more intrusive method of getting ten cents off on paper towels. They're working on using kiosks at the store's entrance (which probably no one will stop at) to send ads, sales and specials to cellphones and PDAs via Bluetooth or IR. How are we supposed to sign up as I.C. Weiner of 123 Anyplace Street if our cellphone is beaming the store all of our demographic information?
