Radio Frequency Identification (RFID) uses electromagnetic fields to automatically identify and trace labels attached to objects. Labels contain information stored electronically. Passive tags collect the energy of interrogation radio waves from a nearby RFID reader. Active tags have a local power supply, such as a battery, and can operate hundreds of meters from the RFID reader. Unlike a bar code, the label does not need to be within the line of sight of the reader, so it may be embedded in the crawled object. RFID is a method for automatic identification and data capture (AIDC).
RFID tags are used in many industries, for example, you can use an RFID tag attached to a car during production to track your progress through the assembly line; RFID-labeled pharmaceuticals can be screened through warehouses; and the implantation of RFID microcircuits in cattle and domestic animals allows positive identification of animals.
Since RFID tags can be connected to cash, clothing and possessions, or implanted in animals and people, the ability to read personally linked information without consent has raised serious privacy concerns. These concerns resulted in the development of standard specifications addressing privacy and security issues. ISO / IEC 18000 and ISO / IEC 29167 use on-chip cryptography methods for non-traceability, label and reader authentication and privacy in the air. ISO / IEC 20248 specifies a digital signature data structure for RFID and bar codes that provide data authenticity, source and method of reading. This work is done within ISO / IEC JTC 1 / SC 31 Automatic identification and data capture techniques.
In 2014, the global RFID market is worth $ 8.89 billion, more than $ 7.72 billion in 2013 and $ 6.96 billion in 2012. This includes tags, readers and software / services for RFID cards, tags, fobs and all other form factors. Market value is expected to increase to US $ 18.68 billion by 2026.
