Abstract
There is provided a wireless portable device for providing location-based data to a user in a defined geographical area including a plurality of points of interest, the wireless portable device comprising a wireless transmitter, a wireless receiver, and an expansion bay with an attached expansion cartridge. The wireless transmitter can transmit location information to a wireless server over a wireless network. The wireless receiver can receive location-based data relating to a point of interest from the wireless server periodically and automatically, based on the location of the wireless portable device. The expansion cartridge can receive location-based data while the wireless portable device is in a low power sleep state. There is also provided a method for a wireless server to provide location-based data to a wireless portable device after a pre-determined period of time, including an interactive game relating to a point of interest.
