The world’s smallest and thinnest sensor that reads palm vein to authenticate the user has been developed by Fujitsu. It can easily be built in electronics devices for authentification using palm. With the user-friendliness and strong security capability, it is expected to increase the competitiveness of electronic devices. It is 29 mm both in width and depth, and 11.2 mm in height. Besides making the lens thinner, Fujitsu increased the integration degree of the substrate and successfully reduced the volume to less than one third of the existing systems it has developed to make the sensor world’s smallest and thinnest. Fujitsu developed this system in alliance with Fujitsu Frontech, one of its subsidiaries, that develops and builds industrial machinery like ATMs. Featuring the ability to provide a high degree of security without the necessity to input the password or put an ID card, the company will launch notebooks PCs incorporating this authentification system for industrial use shortly. It is planning to put the notebook PCs of this kind on the consumer market too in the future. The world market of sensors that read vein and fingerprint is expected to grow at a rate of 20% on average annually.
