Method and apparatus for communicating with a product label

摘要

A method and apparatus for communicating with a product label. A host computer transfers information to be communicated to one or more product labels to a radio frequency transmitter. The information is transmitted to a transceiver built into the product label. The information can be intended for each of a plurality of product labels, or for a particular one of the product labels. If the particular one of the labels is one which has not communicated recently with the host computer, the information can used to locate the particular label through the use of other product labels.
