Japanese stores use RFID to let customers bookmark their favorite shops

Tokyo-based TechFirm is launching an RFID-based service that lets stores and customers exchange information. By pairing a shopper's RFID-enabled phone with RFID readers in the stores, customers can download and save information about the store — a bookmark of sorts for favorite shops. The incentive for the stores is that the exchange is two-way,
and shops can collect lists of potential repeat customers in order to send them spam special offers and bargains. Maybe stores in Japan will actually make sensible usage of their customers' data, but we would be the first to opt out if something like this ever hit the States.
