Abstract
In a tag identification system, active tags are configured to emulate at least one passive tag so that existing passive identifications systems, such as passive radio-frequency (RFID) systems or near field communication (NFC) systems, can be retrofitted to operate with the active tag without having to make expensive hardware updates to the readers within the system. The active tag permits continuous monitoring of its movement or status, as may be desired, regardless of its proximity relative to the readers thereby allowing a system to capture more data regarding the tag's location and use. In addition, the active tag may be compatible with different passive identification systems thereby permitting it to operate with disparate passive identification systems and obviating the need of the user to carry multiple passive tags.
