Fujitsu Laboratories has announced development of the world’s first slide-style palm vein authentication technology. This technology is compact enough to be equipped to future tablets and other handheld mobile devices. As tablets and other small-scale mobile devices have become widespread, there has been interest in embedding an optical unit for vein authentication into the narrow frames of such devices, but making the optical unit smaller had been difficult. Fujitsu Laboratories has now taken strides to overcome this issue. It has succeeded in developing a compact illumination component that lights up a rectangular target area with a uniform intensity using a single LED.
