APPARATUS FOR EXCHANGING REMOTE DEALING SYSTEM BASED ON LOCALITY AND PROXIMITY OF CONTROL DEVICE TO REMOTE SENSING SOURCING DEVICE

摘要

A personal RFID lost and found system used a mobile apparatus and methods useful for tracking luggages during traveling, the luggages are typically stored out-of-sight and signal needs to pass thru obstacles. The system may be used with a single tag, as well as more than one tag for the tracking of multiple items. A RFID tag replies with information regarding the whereabout of the tag. A GPS locator replies with information regarding geolocation of a RFID reader. A processor connected to the RFID reader infers a distance point according to which the RFID passive tag respond, the magnitude and phase of the returned signals, and the geolocation of the GPS locator. A series of the distance points to the passive tag are stored in a memory for extrapolation to determine the last known geolocation of the passive tag. Upon determining the distance to the passive tag exceeds a preset value, the last known geolocation of the passive tag is presented to assist in locating lost items.
