PROBLEM TO BE SOLVED: To provide a method for making a remote measurement of motion employing an RFID as an RFID system is normally not employed as a measuring instrument. SOLUTION: This system and method for making measurements using RFID systems (10, 80) includes transceivers (12, 82), transponders (20, 40, 92, 94) and a sensor configured within the transponder. The transceivers are configured to transmit and receive radio frequency signals. The transponders are configured to receive the radio frequency signals from the transceivers, and to transmit the radio frequency signals to the transceivers, and provided with a sensor (60). The transceiver is configured to transmit an activation signal to the transponder thereby enabling the sensor to make a vibration measurement, and to hold the measurement value.
