Radio-frequency identification chips (often called RFID tags) are passive, inductively powered chips that are used for numerous applications, from substituting bar codes on supermarket products to discovering lost dogs and cats. It is a tiny, battery-powered electronic device that can be taken around to warn its possessor that a new RFID tag has been positioned in his or her locality or that his or her tags are presently being scanned. One of the introductory RFID TAG development companies, Alien Technology leads the industry in developing high-quality compliant RFID tags, readers and printers for companies worldwide. Once the RFID tag is activated, the tag decodes the incoming query and makes an proper reply by utilizing the energy of the incoming radio wave to power the chip long enough to reply.

Some other companies are using RFID for a large kind of applications. Some of these applications include: supply chain management, automatized payment, physical access control, counterfeit prevention, airline luggage management, and smart homes and offices. The following are the most common forms of tags: Label: The tag is a flat, thin, flexible form. Ticket: A flat, thin, flexible tag on paper .Card: A flat, thin tag embedded in tough plastic for long life. Glass bead: A small tag in a cylindrical glass bead, used for applications such as animal tagging (e. Assorted frequencies have different characteristics that make them more useful for several applications.)

RFID TAGS bring value and accuracy to many applications such as: Compliance labeling in retail distribution centers. High-speed processes in postal and parcel distribution. Manufacturing process control and verification, material tracking, Airline luggage identification and routing systems, and Single-pass multiple item identification. RFID technology can be utilized to raise productivity and tracking in discrete and process manufacturing. For RFID applications such as toll collection and vehicle and container tracking, the tags are used over and over for many years. The most usual applications are payment systems (Mobil Speedpass and toll collection systems, for instance ), access control and asset tracking. Active and semi-passive rfid tags are useful for tracking high-value goods that need to be read over long ranges, such as railway cars on a track, but they cost more than passive tags, which means they can't be utilized on low-cost items.

However, the ease with which RFID tags can be tracked opens up the door to invading people's privacy. The accelerated adoption of RFID technology has produced worries with some groups involved with privacy such as the Electronic Frontier Foundation and the American Civil Liberties Union . Civil liberties groups are afraid about RFID technology being abused to invade people's privacy; RFID tags enable unethical individuals to snoop on people and sneakily collect information on them without their approval or even knowledge.

RFID tag technology, a replacement to bar code technology, identifies tagged items over radio communication between an electronic reader and tags carrying data on microprocessor chips. The major disadvantages of a passive rfid tag are: The tag can be read only at very close distances, typically a few feet at most. Passive RFID tags are more suitable for warehousing surroundings where there is not a lot of interference, and comparatively short distances (typically ranging anywhere from a few inches to a few yards).
