摘要

Systems and methods for operating a Radio Frequency Identification (“RFID”) tag. The methods comprise: monitoring a level of Radio Frequency (“RF”) energy being received by the RFID tag; performing operations by a circuit of the RFID tag to compare the level of RF energy in a given frequency band to a first threshold value; and transitioning an operational mode of the RFID tag from a first operational mode in which a receiver is disabled to a second operational mode in which the receiver is enabled, when the level of RF energy exceeds the first threshold value. The RFID tag is able to communicate with a remote tag reader when the RFID tag is in the second operational mode and not when the RFID tag is in the first operational mode.

Lowering the power threshold would mean that the people doing the inventory cycle counts would not have to get very close to all products. They could complete the task faster if they could read tags up to 10 meters away.

Illustrative Systems

Referring now to FIG. 1, there is provided a schematic illustration of an illustrative system 100 that is useful for understanding the present solution. The present solution is described herein in relation to a retail store environment. The present solution is not limited in this regard, and can be used in other environments. For example, the present solution can be used in distribution centers, factories and other commercial environments. Notably, the present solution can be employed in any environment in which objects and/or items need to be located and/or tracked.

The system 100 is generally configured to allow improved inventory counts of objects and/or items located within a facility. As shown in FIG. 1, system 100 comprises a Retail Store Facility (“RSF”) 128 in which display equipment 1021, . . . , 102M is disposed. The display equipment is provided for displaying objects (or items) 1101-110N, 1161-116X to customers of the retail store. The display equipment can include, but is not limited to, shelves, article display cabinets, promotional displays, fixtures and/or equipment securing areas of the RSF 128. The RSF can also include emergency equipment (not shown), checkout counters and an EAS system (not shown). Emergency equipment, checkout counters, and EAS systems are well known in the art, and therefore will not be described herein.
