Abstract

A multichannel switched communication system having a plurality of communication channels, comprising a plurality of information records stored in a database relating to a plurality of identified objects; a database server system for selectively accessing information records based on a selection criteria; a common input, receiving said selection criteria associated with an identification of a receiver, said selection criteria including object identification information; and a multichannel distribution system capable of simultaneously transmitting a plurality of information records, for transmitting said selectively accessed information record to said identified receiver. A plurality of mobile receivers each receives a desired broadcast on one of a plurality of channels. A bar code scanner associated with a mobile receiver identifies desired information record for retrieval. An infrared or radio frequency communication system may be provided for transmitting control data from the mobile receiver.
