Origin of RFID tags
Leon Theremin is assumed to be the first user or inventor of this device as the inevitable part of spy-kit for the Russian Government in 1945. This cannot be a reliable story: the tool introduced by Theremin was obviously a passive covert listening device and not an identification tag. The technology utilized for RFID has been since the early 1920s. The IFF transponder, a much more relevant technology, developed in 1939 and the British utilised it during the World War 2 to identify airplanes whether they were friends or foes.
What is RFID?
RFID is definitely an all-encompassing expression for technologies that employ radio waves to recognize people or objects automatically. After storing a serial number or any other identification data on the chip connected to an antenna, user can use a reader to receive radio waves on the chip and convert the signal into digital information, that may be ignored to computers and be used of.
This technology finds its maximum usage in payment systems, access control and asset tracking. For example, the logistics industry often uses it in making out large cargos.
RF technologies have an extensive use in many areas of electronics and technology such as television, radio, cellular phones, radar and automatic identification systems. RFID (Radio Frequency Identification) provides Automatic Identification of things by utilizing radio frequency signals. RFID is utilized in numerous applications like toll collection (electronic), railway car identification and tracking, intermodal container identification, asset identification and tracking, item management for retail, health care and logistics applications national, access control, animal identification, fuel dispensing loyalty programmes, automobile immobilizing and so on.
Radio Frequency (RF) makes reference to electromagnetic waves with a wavelength that fit to use in radio communication. Categorized by their frequencies, radio surf is suggested for kilohertz, megahertz or gigahertz. Radio frequencies range from very low frequency (VLF), that features a range of 10 to 30 kHz, to very high frequency (EHF), which has a range of 30 to 300 GHz.
RFID - An Outline
RFID is the fittest and supple technology for automatic operation due to its resilience. It offers benefits unavailable in other identification technologies. RFID perform under various environmental situations and offers a superior quality of data integrity. Moreover, considering that the technology is hard to simulate, it gives advanced level of security.
Essentially RFID isn't distinctive from bar coding. Bar code uses a reader and coded labels that are attached to an item, whereas RFID employs a reader and special RFID tools that are connected to an item. To deliver information from the label to reader, Bar code employs optical signals but RFID uses RF signals for the same.
Radio waves communicate between a specific thing to which an RFID system is attached and an RFID reader. The tool can have information of the item, such as what the item is, what time a device takes to travel through a specific area, even a parameter such as temperature. Practically, RFID tools for instance a tag or label could be linked to anything - from a vehicle to a pallet of merchandise.Click For More Info RFID Tags
