Abstract

A method for error free initialization of a display tag includes providing a display tag, scanning the display tag with a near field source to cause the display tag to generate identification indicia, storing the identification indicia if only a single display tag generates that identification indicia, scanning the barcode of a product to be associated with the display tag, and associating, in a database, the identification indicia of the display tag with the barcode of the product to be associated with that display tag.

Claims

1. A method for initialization of a display tag comprising the steps of

placing a display tag on a shelf adjacent a product to be associated with the display tag;

waking up the display tag using an RF signal from a handheld device;

obtaining an identification indicia of the display tag stored on the display tag using the handheld device while the display tag is on the shelf;

scanning, using the handheld device after the identification indicia of the display tag is obtained, the barcode of the a product to be associated with the display tag that is adjacent the display tag on the shelf;

associating, in a database, the identification indicia of the display tag with the barcode of the product to be associated with that display tag; and

wirelessly initializing the display tag having the identification indicia with product information for the product with the barcode using the identification indicia and product barcode in the database.

2. The method of claim 1 wherein the display tag generates the identification indicia as a transmitted signal.

3. The method of claim 1 wherein the display tag generates the identification indicia as a visual display.

4. The method of claim 1 further comprising enclosing a plurality of displays.

5. The method of claim 1 further comprising displaying data on the display using control logic.

6. The method of claim 5 further comprising communicating with the control logic of each display by wireless techniques.

7. The method of claim 5 further comprising communicating with the control logic of each display by optical techniques.

8. The method of claim 5 further comprising communicating with the control logic of each display by a wired connection.
