An RFID tag can be affixed to an object and used to track tools, equipment, inventory, assets, people, or other objects. RFID offers advantages over manual systems or use of barcodes. The tag can be read if passed near a reader, even if it is covered by the object or not visible.
Examples include an identifying integrated circuit RFID device encased in silicate glass which is implanted in the body of a human being. This type of subdermal implant usually contains a unique ID number that can be linked to information contained in an external database, such as identity document , criminal record , medical history ...
X-ray image of a microchip implant in a cat. A microchip implant is an identifying integrated circuit placed under the skin of an animal. The chip, about the size of a large grain of rice, uses passive radio-frequency identification (RFID) technology, and is also known as a PIT (passive integrated transponder) tag.
The AAR selected four systems for extensive field tests. General Electric developed an RFID system, ABEX a microwave system, Wabco a black and white barcode system, and General Telephone and Electronics (GTE) a color barcode system called KarTrak. The RFID system used a tag mounted under the rail car and an interrogator installed between the rails.
RFID on metal (abbreviated to ROM) are radio-frequency identification (RFID) tags which perform a specific function when attached to metal objects. The ROM tags overcome some of the problems traditional RFID tags suffer when near metal, such as detuning and reflecting of the RFID signal, which can cause poor tag read range, phantom reads, or no read signal at all.
The Octopus card is the first major public transport system to use the Sony 13.56 MHz FeliCa radio frequency identification (RFID) chip. [66] [67] It is a contactless system, so users need only hold the card in close proximity to the reader.
Radio-frequency identification (RFID) is the use of an object (typically referred to as an "RFID tag") applied to or incorporated into a product, animal, or person for the purpose of identification and tracking using radio waves. Some tags can be read from several meters away and beyond the line of sight of the reader.
RFID is a wireless technology supported by many different vendors for tags (also called transponders or smart cards) and readers (also called interrogators or terminals). ). In order to ensure global operability of the products multiple test standards have been develo
