A beautiful post, which I understand about the content of your post RFID technology starts when a soviet spy (now Russia) invented the radio wave transmission system through audio information. The sound waves vibrate the diagrammas that have formed into a resonator that modulates the reflected wave . Although this tool is not an identification but is considered a precursor to RFID technology. In addition there are also IFF transponder technology used by the British army in the 2nd world war for aircraft goods as friends or enemies. RFID device that became the embryo of modern RFID system is Device Mario Cardullo, for using passive radio transponders with memory. Cardullo's basic patented use of RF, voice and light as a transmission medium. RFF was offered to investors in 1969 for use in the field of transport, train, security and medical.
Then the working principle of RFIDRFID uses identi system fication with radio waves. For that it takes at least two devices, namely called TAG and READER.Saat scanning data, READER read the signal provided by RFID TAG.
Thaks you...
