Abstract:
1. A location information processing center for managing location information for objects to be stored and retrieved at various locations in an area, comprising: memory storing a database including fixed device identifiers, each fixed device identifier being associated with a fixed contactless identification device, each fixed contactless identification device exhibiting a fixed device identifier that can be detected from a distance, the database further including mapping information associating fixed device identifiers with locations in the area; a communication interface for receiving messages from a mobile locator operative to read movable device identifiers from movable contactless identification devices, each movable contactless identification device exhibiting a movable device identifier, the mobile locator being operative to read fixed device identifiers from fixed contactless identification devices and movable device identifiers from movable contactless identification devices in the vicinity of the fixed contactless identification devices and to transmit messages to the location information processing center including identifiers of movable contactless identification devices and fixed contactless identification devices in the vicinity of the movable contactless identification devices; and a processor for identifying a location of a movable contactless identification device based on messages including the identifier of the movable contactless identification device and fixed contactless identification devices in the vicinity of the movable contactless identification device.
