Casio has successfully combined a 1.2-inch LCD screen and an optical fingerprint sensor, potentially allowing manufacturers to include biometric security in small, space-deficient devices like cellphones.
The technology uses optical sensors placed on 0.7mm-think sensor substrate that is placed on a standard TFT LCD screen, saving space while improving on fingerprint-sensing technology. According to Casio, the optical sensor technology is superior to other types, such as CCD or capacitor systems, because of the optical substrate??s accuracy and ability to be effective in less-than ideal conditions such as dirty or dry fingers. The technology is still about a year away due to software development concerns, so don??t get your thumbs all bent out of shape just yet.
