Abstract
Deactivating a data tag attached to packaging for user privacy or tamper-evident reasons. A data circuit stores identification information. A plurality of antennas is coupled to the data circuit. At least one antenna of the plurality of antennas is a removable antenna capable of wireless signal transmission at a first range such that removal of the antenna substantially prevents communication of the identification information via the removed antenna and permits communication of the identification information via another antenna of the plurality of antennas at a second range relatively smaller than the first range.
