The present solution is not limited to that shown in FIG. 2. The tag 200 can have any architecture provided that it can perform the functions and operations described herein. For example, all of the components shown in FIG. 2 can comprise a single device (e.g., an Integrated Circuit (“IC”)). Alternatively, some of the components can comprise a first tag element (e.g., a Commercial Off The Shelf (“COTS”) tag) while the remaining components comprise a second tag element communicatively coupled to the first tag element. The second tag element can provide auxiliary functions (e.g., motion sensing, etc.) to the first tag element. The second tag element may also control operational states of the first tag element. For example, the second tag element can selectively (a) enable and disable one or more features/operations of the first tag element (e.g., receiver operations), (b) couple or decouple an antenna to and from the first tag element, and/or (c) cause an operational state of the first tag element to be changed (e.g., cause transitioning the first tag element between a power save mode and non-power save mode).

Referring now to FIG. 3, there is provided a detailed block diagram of an exemplary architecture for a tag reader 300. Tag reader 120 of FIG. 1 is the same as or similar to tag reader 200. As such, the discussion of tag reader 200 is sufficient for understanding tag reader 120.
