Abstract:
1. A method of disabling a data tag device, the data tag device having tag circuitry and a battery on the data tag device, the battery being initially coupled to the tag circuitry, the data tag device further having a decoupling feature configured to destructively decouple the battery from the tag circuitry, the method comprising: operating the data tag device in an operational mode selected from an active mode and a semi-active mode; while operating the data tag device in the operational mode, decoupling the battery from the tag circuitry by use of the decoupling feature; detecting decoupling of the battery from the tag circuitry; changing tag data stored on the data tag device in response to detecting the decoupling of the battery; and ceasing operation of the data tag device in the operational mode.
