Origin of RFID tags

Leon Theremin is thought is the first user or inventor on this device as the inevitable part of spy-kit for the Russian Government in 1945. This cannot be a reliable story: the tool invented by Theremin was a passive covert listening device and not an identification tag. We’ve got the technology applied in RFID has actually been since the early 1920s. The IFF transponder, a more relevant technology, developed in 1939 and the British utilised it in the course of the World War Ii to identify airplanes if they were friends or foes.

What is RFID?

RFID is definitely an all-encompassing expression for technologies that employ radio waves to acknowledge 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, which is often 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 regions of electronics and technology such as television, radio, mobile phones, radar and automatic identification systems. RFID (Radio Frequency Identification) provides Automatic Identification of items by utilizing radio frequency signals. RFID is utilized in various applications like toll collection (electronic), railway car identification and tracking, intermodal container identification, asset identification and tracking, item management for retail, medical care 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 suggested for kilohertz, megahertz or gigahertz. Radio frequencies range from very low frequency (VLF), with a selection of 10 to 30 kHz, to extremely high frequency (EHF), that features 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 inaccessible in other identification technologies. RFID can function under various environmental situations while offering a high quality of data integrity. Moreover, since the technologies are hard to simulate, it gives advanced level of security.

Essentially RFID just isn’t not the same as 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 linked to an item. To transmit information from the label to reader, Barcode makes 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, including what are 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 could be connected to anything – from a vehicle to a pallet of merchandise.
