METHOD AND APPARATUS FOR VERIFYING INFORMATION ASSOCIATED WITH ELECTRONIC LABELS

摘要

Embodiments are directed to methods and apparatuses for determining and verifying a location of an electronic label. A host system exchanges (310) information with the electronic label via ultrasonic data communication. The host system also identifies (320) a location of the electronic label using an ultrasonic location technique. The host system also verifies (330) that the electronic label is correctly located by comparing a calculated location of the electronic label with a known location of merchandise associated with the electronic label
