ABSTRACT:
RFID tags to provide a relatively low power and power conserving wireless communication system to dynamically and automatically transfer all preselected data developed in designated digital devices to a centralized data processing system. Inclusion, in the target mobile wireless devices from which data is to be transferred, of an RFID tag, preferably passive, to minimize power consumption that is conventionally recognizable by a short range RF transceiver in the computer system to which data is to be transferred. Thus, each mobile wireless device being tracked includes a short range RFID tag, a short range RF transceiver and storage means for the digital data developed by the device that is to be transferred. The data processing system to which the transfer is to be made should include a short range RF transceiver for identifying all RFID tags within this short range boundary; and means, responsive to the system RF transceiver identifying the RFID tag in the mobile wireless device within said short range boundary, for transmitting a signal to said mobile device to trigger the mobile device transceiver to transmit stored digital data to the data processing system.
