Method and apparatus for disabling an active data tag device
First Claim
1. A method of changing an operating mode of a RFID data tag device, the data tag device having tag circuitry and a battery carrier configured to allow removal and replacement of a battery in a non-destructive manner, the battery providing power to the tag circuitry, the method comprising:
- operating the data tag device in an active mode while the battery is present in the data tag device;
removing the battery from the battery from the data tag device non-destructively;
detecting removal of the battery from the data tag device;
changing tag data stored on the data tag device in response to detecting the removal of the battery; and
ceasing operation of the data tag device in the active mode and then operating the data tag device in a passive mode.

Abstract
The present invention discloses a data tag device (100) which initially operates in an active mode (304). The data tag device includes tag circuitry including a interface element (104), a controller element (102), and a memory (106) in which tag data (116) is stored. A battery (110) is provided which is initially coupled to the tag circuitry by a connector means (130) which allows non-destructive removal and replacement of the battery. The data tag device is configured to detect the removal of the battery (306, 308), and disable the data tag in response (310).
