ABSTRACT:
The present invention discloses a data tag device (100) which initially operates in a passive mode where the tag responds to queries (412). While operating passively, an expiration event occurs (512, 514) which causes the tag to disable a battery (110), preventing subsequent operation in the passive mode, resulting in the tag disabling access to the tag data.
