What is radio frequency identification (RFID)?

Here's a plain-English explanation of what radio frequency identification is. Radio frequency identification (RFID) is a generic term that is used to describe a system that transmits a unique serial number wirelessly, using radio waves. It's grouped under the broad category of automatic identification technologies.

Auto-ID technologies include bar codes, optical character readers and some biometric technologies. The auto-ID technologies have been used to reduce the amount of time and labor needed to input data manually and to improve data accuracy. Some auto-ID technologies, such as bar code systems, often require a person to manually scan a label to capture the data. RFID is designed to enable readers to capture data on and transmit it to a computer system—without needing a person to be involved.

To retrieve the data stored on the "smart" student identification card, readers are installed throughout the school*. A typical reader is a device that receives signals back from the "smart" card. The reader then passes the information in digital form to a computer system.

RFID technology has been used by thousands of companies for a decade or more.
