The PDA Instant Loyalty Card?

One vendor is trying to get consumers to sidestep the hassle of filling out loyalty card applications at every store by integrating the functionality into a PDA.

The field test by Japan's NTT Communication started this month, just as the vendor promised when it rolled out the program in October 2008. NTT's new "Gyazapo" system, which uses an RFID chip in a mobile phone to carry loyalty card information for multiple retailers, can allow RFID scanners at the POS to grab shoppers' personal information from a central database managed by NTT.
