According to aimglobal.org, radio frequency identifications is technology that uses radio waves to transfer data from an electronic tag. Another definition is a generic term that is used to describe a system that transmits the identity of an object or person wirelessly, using radio waves. For example, let’s say you lose your phone. Radio frequency identifications can help find your phone if you ever lost it. Radio frequency identifications consist of three components: An antenna or coil, transceiver and a transponder (RFTAG). The antenna sends radio signals to activate the tag. When the RFID tag passes through the electronic zone, it detects the activation signals. Then the information is passed to the computer for processing.
The Purpose for radio frequency identifications is to enable data to be transmitted by a portable device called a tag, which is read by an RFID (Radio Frequency Identifications) reader and processed according to the needs of a particular application. The RFID (Radio Frequency Identifications) tag consists of a microchip. Radio frequency identification is used by thousands of companies. Current potential uses of Radio Frequency Identification: asset tracking, manufacturing, supply chain management, retailing, payment system, security and access control.
