The Palmcoder is a small hand-held smart module that allows carriers to reprogram wireless phones with preferred system lists, as well as anti-fraud authentication codes and service enhancements or changes, without the subscriber having to bring their handset to the carrier for reprogramming. A carrier can program this module with an individual subscriber's information for service changes or enhancements. The preprogrammed unit would then be sent to the subscriber, who inserts it into the accessory receptacle of their phone. This product automatically reprograms the phone, which is then ready for immediate use.
After the telephone has been reprogrammed, the subscriber returns the module to the carrier for redeployment. This unit helps a carrier to enhance its fraud prevention programs by enabling the carrier to program a subscriber's wireless telephone with a 26-digit anti-fraud A-Key (authentication-key) code. The carrier system can check that it is a valid key whenever a signal is sent to a cell site, preventing cloning and providing secure roaming for its subscribers.
