- 1. A method of 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; broadcasting a wireless, signal; receiving said signal by a plurality of receiving modules, the receiving modules comprising at least some of the electronic display 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; storing the decoded product information in a memory of the addressed module; and displaying the stored product information on a display of the addressed module responsive to said step of matching.
- 2. 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 products; encoding product information for selected ones of the modules into an infrared signal, 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 to be displayed on at least an addressed one of the modules; aerially broadcasting said signal as pulsed electromagnetic energy to the modules from a remote transmitter; receiving said signal by a plurality of receiving modules through housings of the modules, each housing being transparent to said electromagnetic energy, the receiving modules comprising at least some of the electronic display modules; decoding the address part of said signal by each receiving module into a received address; comparing the received address to a module address of the module; matching the received address to the module address in at least one addressed module among the received modules; for each addressed module, decoding the data part of the signal into product information; storing the decoded product information in a memory of the addressed module; and displaying the stored product information on a display of the addressed module responsive to said step of matching.
