inventor of rfid chip In 1945, Leon Theremin invented the "Thing", a listening device for the Soviet Union which retransmitted incident radio waves with the added audio information. Sound waves vibrated a diaphragm which slightly altered the shape of the resonator, which modulated the reflected radio frequency. Even though this device was a covert listening device, rather than an identification tag, it is considered to be a predecessor of RFID because it was passive, being energised and activ. With this app you can read the information written on the card and the card holder's name. It supports EMV (Near Field Communication) cards as .

Charles Alfred Dodgsons Walton (December 11, 1921 – November 6, 2011 ) is best known as the first patent holder for the RFID (radio frequency identification) device. Many individuals contributed to the invention of the RFID, but Walton was awarded ten patents in all for various RFID-related devices, including his . See more

Who Invented RFID? While many innovators contributed to the development of RFID, historians typically grant the most credit to Charles Walton . He earns this distinction, in part, because he was the first person to hold a patent for the technology.Mario Cardullo 's device, patented on January 23, 1973, was the first true ancestor of modern RFID, [11] as it was a passive radio transponder with memory. [12] The initial device was passive, powered by the interrogating signal, and was demonstrated in 1971 to the New York Port Authority and other potential users. Mario W. Cardullo claims to have received the first U.S. patent for an active RFID tag with rewritable memory on January 23, 1973. That same year, Charles Walton, a California entrepreneur, received a patent for a passive transponder used to unlock a door without a key. In 1946, Leon Theremin was the inspiration for developing a Soviet spy tool that used an RFID-like technology. Theremin created a musical instrument that could be played without physically touching it due to the static frequency waves it generated.
The first of Walton’s RFID-related creations, a portable radio frequency emitting identifier uses an electrical current from a radio transceiver, or reader, to activate a key card when the two are within six inches of each other.
RFID was, however, officially invented in 1983 by Charles Walton when he filed the first patent with the word ‘RFID’. NFC started making the headlines in 2002 and has since then continued to develop.History of RFID. Swedish scientist and inventor Harry Stockman explored RFID in his paper, “Communication by Means of Reflected Power” (1948). At the time, radio technology was still being developed, and it was another few decades before RFID technology became viable. The US-American Mario Cardullo is now considered the inventor of the RFID chip. In 1973, he received the first patent for a passive RFID with read and write access. But the RFID chip from the 1970s also has nothing in common with today’s wafer-thin RFID tags. engadget: Charles Walton, the man who pioneered the rise of RFID technology, has died at the age of 89. The Cornell-educated entrepreneur garnered more than 50 patents over the course of his career, but it only took one to cement his legacy -- a 1973 patent for a "Portable radio frequency emitting identifier."
