The very first patent Walton secured that actually included the acronym RFID .An RFID system consists of a tiny radio transponder called a tag, a radio receiver, and a transmitter. When triggered by an electromagnetic interrogation pulse from a nearby RFID reader device, the tag transmits digital data, usually an identifying inventory number, back to the reader.
The very first patent Walton secured that actually included the acronym RFID was the portable radio frequency emitting identifier, which was awarded several decades after the basic concept of RFID began to emerge.radio-frequency identification (RFID), method of wireless communication that uses electromagnetic waves to identify and track tags attached to objects, people, or animals. The attached tags, called RFID tags, store digitally encoded data that can be read by an RFID reader. 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. Thanks to their small size, RFID tags have been placed into day-to-day objects such as passports, library books, clothes and payment cards. But where did this technology come from? And when was it created? A recent article on the BBC website discusses the Cold War spy technology we all use today.
Often the term "RFID" is loosely used to describe both, but there's a big difference between them: RF tags all send the same, simple signal and simply tell the receiver that something is present; RFID tags send more complex signals that uniquely identify whatever they're attached to. Anti-theft detection and electronic surveillance systems popped up that all used RF tech. However, RFID wasn’t officially patented until 1973, in a landmark claim by Mario W. Cardullo, who created an active RFID tagging system that utilized rewritable memory.It is also said that an early demonstration of reflected power (modulated backscatter) RFID tags, both passive and semi-passive, was performed by Steven Depp, Alfred Koelle, and Robert Freyman at the Los Alamos National Laboratory in 1973. (2) The portable system operated at 915 MHz and used 12-bit tags. RFID timeline: 1973 - RFID first patented. The first patent for commercial RFID tags was granted in 1973 to Mario W. Cardullo, whose RFID tag had a rewritable memory. The same year, California entrepreneur Charles Walton received a patent for a passive transponder used to unlock a door without a key. RFID timeline: 1987 - RFID goes public
Radio-frequency identification (RFID) systems are similar to barcodes in that they identify. That bag of peas could, in the modern era, actually have an RFID tag in or on the bag.
