A radio-frequency identification (RFID) tag is provided that comprises an RFID transceiver configured to transmit and receive radio frequency (RF) signals, the RFID transceiver comprising an integrated circuit chip (IC) coupled to an antenna having an impedance, gain and directionality that in conjunction with the characteristics of the IC defines a first read range of the RFID tag. The RFID tag also comprises a releasable coupler configured to be releasably engagable with the RFID transceiver comprising a coupling material, the releasable coupler being configured such that when the releasable coupler is releasably engaged with the RFID transceiver, the coupling material altering at least one of the impedance, the gain and the directionality of the antenna to define a second read range of the RFID tag, wherein the second read range is greater than the first read range.
