RFID DEMPA (RADIO WAVE) CHECKER CARD DEMO-3



Video of the demo of DEMPA (radio wave) CHECKER CARD with LED mounted on the card. The LED lights up when the card detected UHF radio emission of an effective power level from the antenna of RFID tag reader (interrogator) . The DEMPA CHECKER CARD is a friend of engineers who are responsible for installation and maintenance of the UHF RFID readers and antennas. It tells the engineers whether the antenna is hot or not working, how long and how often the antenna emit the radio, relative power level of the radio, and timing of radio emission relative to the motion sensor and so on. Busy engineers won’t have to walk back and forth to check the PC monitor for the timing of radio emission. Visit http://www.rfid-alliance.com/RFIDshop/TOP for the details (Japanese only)
