Abstract

A low-profile Wireless Display Tag (WDT) fits within the confines of a retail store display shelf-edge C-channel. The WDT may also be used to tag high-value retail item units where it can simultaneously function as a price tag, and an anti-theft device. The invention provides for bidirectional communication between the WDT and a central database. The invention uses a low profile antenna that may be painted onto a surface within the WDT. The WDT is capable of displaying graphics or variable format alphanumeric characters and the placement of display items is user programmable. The WDT uses an RF integrated Circuit (RFIC) that combines the backscatter RF communications method, amplified backscatter RF communications method and the active RF communications method.
