An electronic product information display system includes a plurality of self-contained display modules (10) mounted proximate to respective products. A signal (22) is formed that comprises an address part and a data part, the address part corresponding to a selected module address and the data part encoding product information (18, 20) to be displayed by the addressed module (10). The signal is broadcast from a transmitter (24) remote from a plurality of modules (10). Modules (10) each receive the signal, decode the address part into a received address, and decode the data part into product information (18, 20). The product information is stored and displayed responsive to a match between the module address and the received address. The signal (22) is preferably infrared.

A method for displaying product information at locations proximate to associated products, comprising the steps of: mounting a plurality of electronic display modules at locations proximate to respective different goods; programming each module with a module address; forming a signal comprising address and data parts, the address part representing a module address and the data part representing product information for the module address; aerially broadcasting said signal as electromagnetic energy selected from the spectral band consisting of infrared and light to the modules from a remote transmitter; receiving said signal by a plurality of receiving modules, the receiving modules comprising at least some of the electronic pricing modules; decoding the address part of said signal by each receiving module into a received address; comparing the received address to the module address for each receiving module; matching the received address to the module address in at least one addressed module among the receiving modules; for each addressed module, decoding the data part of the signal into product information; displaying the stored product information on a display of the addressed module responsive to the step of matching; and displaying on each module information that changes less often than said product information.
