Radio frequency identification
Radio frequency identification is known as RFID TAG. The tag is incorporated into persons, products, and animals, and serves in identifying using radio waves. Tags can be read from several meters away using radio waves. Radio-frequency identification uses interrogators, which are known as readers. "Label" is another word sometimes used for an RFID tag.
Radio frequency identification is a powerful technology that can help companies achieve total business visibility. RFID can identify the location of assets, tools, inventory, and people. Companies can optimize business processes which reduces operational costs.
The method of identification is to store a serial number which identifies a person or object. The RFID transponder- the tag or label- has a chip and the antenna together. The antenna transmits information to the reader. Radio waves are reflected back from the tag and are passed on to computers.
The price of tags is based on volume, memory power, and packaging or whether encased or embedded in a label. The price varies from 7 to 15 US cents. If the tags are embedded in thermal transfer labels, the costs may be 15 cents or more. High frequency tags cost a little more.
The waves beamed back to the computer resemble a fingerprint, which identifies the object with the tag. RF energy is used for communications of data by using without RFID tag. However the silicon microchip in the tag does not store a serial number. Conductive polymers, or plastic are used without chip tags.
The common purpose of RFID identifies tracking, recording, storing of products and communicating fast important business issues. AIM is automatic identification and mobility technology. AIM is the main function of the radio frequency identification system. It provides quick and correct information data entry.
