Biometric Identification – This is the process of using a person's unique physical characteristics for computer identification. Current biometric identification methods include identification by fingerprint, voice, iris, and face. Biometric identification is currently being used in many government agencies, as well as large businesses. Some of today’s laptop computers have built-in fingerprint identification pads. Biometric identification is also being tested in many areas such as airports where it speeds frequent travelers through passport lines. Biometric Identification is poised to replace the aggravating passwords that we struggle with today.

Nanotechnology – This is a science that studies ways to control individual atoms and molecules. Nanotechnology research is booming. There are many fields where nanotechnology will certainly produce dramatic results. Methods of manufacturing products are sure to be affected as nanotechnology finds ways to form raw materials into new products without the cutting, grinding, and firing methods that are used in today’s manufacturing plants. Implications for the medical field are mind-boggling, as well. Researchers consider ways to control disease with nanotechnology robots called nano-bots. Nanotechnology has already produced wrinkle-free and stain-resistant fabrics, food packaging that keeps meat fresh longer, and self-cleaning windows. It is possible that in the future nanotechnology could produce nanobots that could eat up cancer cells.

RFID – Radio Frequency Identification is already being used in license plates to identify and charge cars as they drive through tollbooths without stopping. This technology is poised to become the bar coding and identification method of the future. RFID tags are extremely small, barely detectable flakes, or tags of silicon. Some are no bigger than a grain of salt. These silicon tags use radio frequencies to transmit a code that uniquely identifies the tag, and therefore, the item to which the tag is attached.
