摘要： 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.
摘要翻译：低调的无线显示标签（WDT）适用于零售商店显示货架边缘C通道的范围。 WDT也可用于标记高价值零售商品单位，同时可以作为价格标签，以及防盗装置。本发明提供了WDT和中央数据库之间的双向通信。本发明使用可以涂在WDT内的表面上的低调天线。 WDT能够显示图形或可变格式的字母数字字符，并且显示项目的放置是用户可编程的。 WDT使用RF集成电路（RFIC），其组合了反向散射RF通信方法，放大后向散射RF通信方法和有源RF通信方法。
