RFID in USA
RFID USA and UAE providing devices that can be used for RFID file tracking, RFID inventory tracking, RFID jewelry tracking, RFID in retail, RFID asset tracking, RFID in USA, RFID inventory tracking software, RFID solutions and RFID people tracking. RFID (Radio Frequency IDentification acronym in Radio Frequency Identification) is a system for storing and remotely retrieving data using tags, cards, transponders or devices called RFID tags. The fundamental purpose of RFID technology is transmitting the identity of an object (similar to a unique serial number) using radio waves. RFID technologies are grouped under the so-called Auto ID (automatic identification, or automatic identification).RFID tags (RFID Tag, in English) are approximately similar to a sticker that can be attached to or incorporated into a product, animal or person small devices. Contain antennas to enable them to receive and respond to requests by radio from an RFID transceiver. Passive tags require no internal power supply, while lending itself require. One advantage of the use of radio frequency (instead, for example, infrared) is not sight between transmitter and receiver is required. Background At present, the most widespread technology for object identification is to barcodes. However, they have some disadvantages, including limited amount of data to be stored and the impossibility of being reprogrammed. Improving devised was the origin of the RFID technology; was to use silicon chips that could transfer data stored to the reader without physical contact, equivalently infrared readers used to reading barcodes History It has been suggested that the first known device similar to RFID may have been a spy tool Leon Theremin invented by the Soviet government in 1945. The device Theremin was a secret passive listening device, not an identification tag. According to some sources, the technology used in RFID have existed since the early 1920s, developed by MIT and extensively used by the British in World War II (source states that RFID systems have been around since the late 1960s and only recently had popularized by cost reductions). A similar technology, the IFF transponder, was invented by the British in 1939, and was routinely used by the allies in World War II to identify aircraft as friend or foe. It is probably the technology cited by the previous source. Another early work is the RFID is Article 1948 of Harry Stockman, titled "Communication by means of reflected energy" (Proceedings of the IRE, pp. 1196-1204, October 1948). Stockman predicted that "... considerable research and development has to be done before the remaining basic problems in reflected power communication are solved, and before the field of useful applications is explored." It took thirty years of advances in many different fields before RFID became a reality. The antenna used in a tag depends on the application for which it is designed and the operating frequency. Labels low frequency (LF, English low frequency) is usually used as electromagnetic induction. There compact LF tags (such as encapsulated in glass used for human and animal identification) using an antenna on several levels (three coils 100-150 each) around a ferrite core. High frequency (HF, 13.56 MHz) a flat spiral with 5-7 turns and a form factor similar to a credit card is being used to distances of tens of centimeters. These antennas are cheaper than LF since they can be produced by lithography instead of expiration, although both surfaces of an insulating metal and are necessary for cross connection of the outer level within the spiral, which houses the condenser resonance and the integrated circuit.
