Abstract:
1. A tag comprising: operational tag circuitry configured to provide information in response to being activated by one or more reader devices; at least two antenna circuits coupled to the operational tag circuitry, wherein each of the at least two antenna circuits is configured to operate at a different reader-tag distance, and wherein the at least two antenna circuits comprises: a) a first antenna circuit that causes the operational tag circuitry to provide point-of-sale tracking information in response to a far-range, point-of-sale, activation signal; and b) a second antenna circuit that causes the operational tag circuitry to provide at least one of consumption and post-consumption tracking information in response to a near-range activation signal; and at least one disabling circuit coupled to the operational tag circuitry and to at least one of the at least two antenna circuits, wherein the at least one disabling circuit is configured to disable operation of the first antenna circuit in response to a point of sale disable signal.
