Zusammenfassung:Aspects of the present disclosure include methods, systems, and non-transitory computer readable media for transmitting at least one incident radio frequency identification (RFID) signal to a RFID tag attached to a merchandize item, receiving at least one reflected RFID signal from the RFID tag, determining a frequency response of the RFID tag based on the at least one reflected RFID signal, comparing the frequency response to a plurality of baseline frequency responses, and determining a state of the RFID tag based on the comparing.
