Embodiments disclosed generally relate to a wireless identification tag with a response time that varies as a function of incoming signal frequency and system and methods for use thereof. In one implementation, the tag may include at least one antenna tuned to receive energy transmitted at a first frequency and at a second frequency. The tag may also include at least one transmitter. The tag may also include at least one circuit configured to detect whether energy is received in the first frequency or the second frequency, and to cause the at least one transmitter to transmit an immediate response when the second frequency is detected and to transmit a delayed response when the first frequency is detected.
