Dual mode security tags
Abstract:
A tag controller is configured to interface with a tag on a product in a monitoring environment that includes first and second monitoring zones. The first monitoring zone includes first locator devices, and the second monitoring zone includes second locator devices. The tag controller includes processing circuitry configured to facilitate operation of the tag in a first mode to employ wireless communication with the first locator devices or the second locator devices to generate position information usable for locating the tag in the monitoring environment. The first mode defines communication parameters associated with the wireless communication. The processing circuitry may also be configured to determine whether mode switch criteria are met, and direct the tag to switch to operation in a second mode to employ different communication parameters relative to wireless communication with the first locator devices or the second locator devices responsive to the mode switch criteria being met.
