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 error free initialization of a display tag comprising the steps of

providing a display tag which has not been initialized,

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.

2. The method of claim 1 wherein the identification indicia is generated as a transmitted signal.

3. The method of claim 1 wherein the identification indicia is generated as a visual display.
