ABSTRACT:
A data transfer system for an LCD price tagging arrangement includes an electro-optical scanner and one or more LCD price tags. Each LCD price tag is associated with a given product in a retail outlet and carries price or other information relating to that product. The LCD price tag includes an electro-optical detector for detecting a beam generated by the scanner. The scanner light beam generating source is modulated such that the beam carries product information. Accordingly the price or other product information on the LCD price tag can be quickly and efficiently updated.
