The attachment of transponders to products as an alternative to barcodes to enable product or item identification some distance from a scanner or when out of line of sight.
The use of radio frequency technology such as RFID tags and tag readers to identify objects. Objects may include virtually anything physical, such as equipment, pallets of stock, or even individual units of product.
This refers to the ability to identify products through the use of small radio transponders, activated by a transmitter, to identify products. The transponder can carry a unique ID code or other information in its memory, and can be read at a distance without line of sight.
RFID is a technology that incorporates the use of electromagnetic or electrostatic coupling in the RF portion of the electromagnetic spectrum to uniquely identify an object, animal, or person. RFID is coming into increasing use in industry as an alternative to the barcode. The advantage of RFID is that it does not require direct contact or line-of-sight scanning. An RFID system consists of three components: an antenna and transceiver (often combined into one reader) and a transponder (the tag). The antenna uses RF waves to transmit a signal that activates the transponder. When activated, the tag transmits data back to the antenna. The data is used to notify a programmable logic controller that an action should occur. The action could be as simple as raising an access gate or as complicated as interfacing with a database to carry out a monetary transaction.
A method of identifying unique items using radio waves. Typically, a reader communicates with a tag, which holds digital information in a microchip. But there are chipless forms of RFID tags that use material to reflect back a portion of the radio waves beamed at them.
A technology in which a tag is attached to each item, which broadcasts a unique, low-frequency radio signal.
A wireless system for transmitting basic data, which consists of an antenna and receiver on one end and a transponder (or tag) on the other end. A common example of an RFID can be found in fast lanes at toll booths. RFIDs are an alternative to bar codes or other identifiers that require line of site or some kind of contact to transmit data. They are also gaining prominence because they are inexpensive to produce and easy to adapt. They can be put into tires or woven into clothes, for example. However, many privacy advocates are concerned about widespread use and the abuse of this technology, which could easily collect data without one knowing it's happening.
Also known as RFID, it is a technology that has existed for decades. At a simple level, it is a technology that involves tags that emit radio signals and devices called readers that pick up the signal.

n. an identification technology using short range radio frequency transmission
The attachment of transponders (which may be read only or read/write) to products, as an alternative to linear bar codes, to enable product identification some distance from the scanner or when out of line of sight.
Radio Frequency Identification (RFID) is an automatic identification method, relying on storing and remotely retrieving data using devices called RFID tags or transponders. An RFID tag is an object that can be attached to or incorporated into a product, animal, or person for the purpose of identification using radio waves. Chip-based RFID tags contain silicon chips and antennae.
