Jr. Attorney, Agent or FirmInternational ClassH04Q 001/00AbstractA method and apparatus for object identification which includes a portable electronic tag reader having a transceiver capable both of reading identification information from electronic tags and transmitting collected information to a base unit for remote analysis. The system of the present invention utilizes the same transceiver to receive information from the base unit and write data to read/write electronic tags. The system of the present invention includes a transceiver for generating a modulated or unmodulated radio frequency interrogation signal, a receiver for detecting a return signal from an electronic tag and a signal processor for processing the return signal. A modulator within the portable unit combines the identification data with the radio frequency interrogation signal for transmission to a base unit through a wireless local area network. A demodulator within the portable unit extracts data and commands received from a base unit for local processing or transfer to a read/write electronic tag. In one embodiment, the portable electronic tag reader includes a user interface for initiating commands and a user display for displaying status information associated with the reading, downloading, or uploading processes.Field of SearchInterrogator-responderRADAR TRANSPONDER SYSTEM Unique identity With Telemetry Radar transponder only Inventory SYSTEMS CONTROLLED BY DATA BEARING RECORDS Credit or identification card systems Particular sensor structure Inventory management Input by product or record sensing (weighing, scanner processing) Inventory monitoring With a common signal processing stage Common antenna | |
