The article I found was on Biometric Sensors. They combined psychical traits of the body with digital technology. It is a really good way for security so you can ensure that you and only you are on your computer or on your accounts. They can detected fingerprints, your face or vein structures and it will be used for faster technology. It will also prevent less fraud in the internet world and is good for keeping government things safer than they already are. Overall this sensor is great for security and can really help in many ways.
