Systems and methods are disclosed pertaining to a programmable display tag that displays consumer information, such as pricing information. The tag is typically portable microcomputer controlled device containing its own power source, memory, and input keys and displays information on an display, typically a color or black and white LCD screen. The programmable display tag is remotely programmed by a display management system that communicates display data using a wireless protocol, such as the IEEE 802.15.4 based protocol. A wireless application protocol allows the display management system to read and write display data, as well as control various administrative functions. Typical applications include remote updating of prices for goods in a retail environment, such as a grocery store, but the display tag can used for other applications, such as a portable display device to display text, graphical, or animated displays for consumers, industrial, shipping, marketing, or other applications.
