Systems and methods for detecting potential shrink events within a venue are provided. The example systems include, a plurality of RFID readers disposed throughout the venue and a controller operatively coupled to the plurality of RFID readers. The controller includes a processor and a non-transitory machine-readable memory storing machine-readable instructions that, when executed by the at least one processor, cause the example systems to (1) monitor RFID tag data associated with an RFID tag disposed within an environment, the RFID tag data including an environmental metric associated with at least a portion of the environment; and (2) responsive to a change in the RFID tag data exceeding a predetermined threshold, generate an alert indicative of a potential shrink event. The change in the RFID tag data may include a change in the environmental metric resulting from a positioning of the RFID tag relative to a body of an individual.
