Abstract

A method and system for updating information stored in portable electronic devices based on the geographic location of the electronic devices is disclosed. The portable electronic devices are provided with built-in transceiver modules which will automatically communicate with base stations provided at centralized high traffic locations. The base stations transmit low power radio signals to the portable devices that contain commands for the devices to automatically update information stored in the portable devices based on the geographic area, such as for example updating to a new telephone area code or time zone. Additionally, a global positioning satellite (GPS) system can be utilized to automatically set the transceiver modules in the portable electronic devices to the proper frequency at which the base stations are transmitting thereby ensuring a communication link between the base station and the portable electronic device. Alternatively, a GPS system can be utilized to update information stored in the portable electronic devices based on the geographic location of the electronic devices.
