Abstract
Methods and apparatuses for activating an electronic tag with an identifier via an access to a storage area of the electronic tag without database or authentication operations are described. The storage area may be accessed as a scratch pad memory. The identifier can identify an inventory including a plurality of articles. One of the articles is attached with the electronic tag. The electronic tag is active if the identifier is stored in the storage area. When the electronic tag is located within a proximity of the electronic gate device, the electronic tag may be inspected wirelessly from the electronic gate device. An alarm may be activated or caused via the electronic gate device if the inspection indicates the electronic tag is active.
