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.
