The present invention is directed to a device and method for displaying content of a radio frequency identification (RFID) tag. The device includes an RFID reader, an interface module, and a laser projection display (LPD). The RFID reader sends instructions to and receives data from an RFID tag. The interface module converts the received data into a format for display. The LPD displays information relating to the data received from the RFID tag. The LPD may display the information directly on an item to which the RFID tag is affixed, or it may display the information on a screen diffuser. The information that is displayed may be numerical data stored in the RFID tag, an iconographic representation of an item to which the RFID tag is affixed, a full resolution image of the item to which the RFID tag is affixed, or the like. |
