Origin of RFID tags

Leon Theremin is assumed is the first user or inventor on this device on the grounds that the inevitable part of spy-kit for the Russian Government in 1945. This cannot be a reliable story: the tool invented by Theremin has been a passive covert listening device and not an identification tag. We now have used in RFID has been since the early 1920s. The IFF transponder, a much more relevant technology, developed in 1939 and the British utilised it through the Second World War to identify airplanes if they were friends or foes.

What is RFID?

RFID is definitely a all-encompassing expression for technologies that employ radio waves to identify 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 within the chip and convert the signal into digital information, which can be passed over to computers and be used of.

This technology finds its maximum usage in payment systems, access control and asset tracking. As an example, the logistics industry often uses it in making out large cargos.

RF technologies have an extensive use in many regions of electronics and technology such as television, radio, cell phones, radar and automatic identification systems. RFID (Radio Frequency Identification) provides Automatic Identification of items by using radio frequency signals. RFID can be used in various applications like toll collection (electronic), railway car identification and tracking, intermodal container identification, asset identification and tracking, item management for retail, healthcare and logistics applications national, access control, animal identification, fuel dispensing loyalty programmes, automobile immobilizing and so on.

Radio Frequency (RF) makes mention of electromagnetic waves with a wavelength that fit to use in radio communication. Categorized by their frequencies, radio surf is indicated in kilohertz, megahertz or gigahertz. Radio frequencies range from very low frequency (VLF), with 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 provides a superior quality of data integrity. Moreover, since the technologies are hard to simulate, it gives advanced level of security.

 

Essentially RFID is not different 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, Barcode make use of optical signals but RFID uses RF signals for similar.

Radio waves communicate between something to which an RFID device is attached and an RFID reader. The tool can have information of the item, for example what the item is, what time a device takes to travel through a certain area, even a parameter such as temperature. Practically, RFID tools like a tag or label may be attached to anything – from a vehicle to a pallet of products.
