RFID Devices – The Future Technology

Radio frequency identification (RFID) is a generic term that is used to describe a system that transmits the identity (in the form of a unique serial number) of an object or person wirelessly, using radio waves. RFID technology does not require contact or line of sight for communication.

The purpose of an RFID system is to enable data to be transmitted by a portable device, called a tag, which is read by an RFID reader and processed according to the needs of a particular application.

To retrieve the data stored on an RFID tag, you need a reader. A typical reader is a device that has one or more antennas that emit radio waves and receive signals back from the tag. The reader then passes the information in digital form to a computer system.

Among the many uses of RFID technology is its deployment in libraries. This technology has slowly begun to replace the traditional barcodes on library items (books, CD’s, DVD’s, etc.). The Radio frequency identification tag can contain identifying information, such as a book’s title or material type, without having to be pointed to a separate database (but this is rare in North America). The information is read by an RFID reader, which replaces the standard barcode reader commonly found at a library’s circulation desk.

As RFID technology evolves and becomes less expensive and more robust, RFID provides you RFID solutions for new applications to solve common and unique business problems. The innovative and upcoming RFID’s Xtenna based devices can track the BSE landmark building’s parking lot for incoming/ outgoing vehicles thereby making it possible to track the unique identities of the vehicles.
