1. A method for displaying information on a dynamic visual RFID tag comprising the steps of:
- providing a visual RFID tag including a display, an RFID tag, a communications module, a display microcontroller; and
an internal energy source wherein the communications module communicates with the display microcontroller wherein the display is self-powered or battery powered;
providing unique information to display on the display of each of a plurality of dynamic visual RFID tags;
using the visual RFID tag unique identifier to identify and compile the unique information transmitted to the dynamic visual RFID; and
displaying the complied information on the display in response to a display prompt wherein the information displayed on the display is derived from information sent from a computer and received wirelessly by the communications module wherein the display prompt is one or more of a change of location of the visual RFID tag and an RFID reader interrogation and wherein data for two or more displays of visual information is held in an integrated circuit associated with the RFID tag and wherein the display prompt is a unique signal that prompts the integrated circuit to direct a single type of the two or more displays of visual information to the display.
