Abstract (en)
[origin: WO02075952A1] A system for communicating label specific information which comprises a communication network (20) in communication with a computer database (18), at least one transceiver (10), and a plurality of labels (12). Each label (12) is disposed on an object in the environment with which a unique identification code is associated and is configured and is configured to transmit a lightwave signal (A) indicative of the code. The transceiver (10) is configured to receive the lightwave signal (A), process the lightwave signal (A) to obtain the code, communicate through the communication network (20) with the computer database (18) to download information associated with the unique identification code obtained and communicate the information to a user.
