Abstract
A system is provided which includes a GPS receiver which determines its location as defined by three spatial coordinates and an associated time reference. The system includes a control logic unit which determines whether the location of GPS receiver is outside the permitted boundaries configured into an internal database in the system. The control logic unit is configured to transmit information related to the location of the GPS receiver to a remotely located interrogator apparatus which communicates back to the control logic unit, instructions regarding determination and reporting of the location of the GPS receiver. An interrogator, if included with a database, can be used as a shopping assistant to aid a shopper in locating desired items by polling a number of the GPS receiver, each associated with a different item, and informing the shopper of the floor, store, aisle or shelf where the item is located.
