Fujitsu today announced a practical version of the world's smallest, slimmest and lightest contact-free vein authentication sensor.

There are a multitude of vein authentication devices in the market, including those for the finger or back of the hand, but the newly developed sensor is unique for its compact form factor, being 5.2 mm thinner and 56% lighter than conventional sensors. At approximately 4.0 g, the size has been reduced to a 25.0 mm width, a 25.0 mm depth, and a height of 6.0 mm. This makes it easier to incorporate into a broader range of , including the thinnest of today's and tablets. This, in turn, helps to expand the range of potential applications for palm vein authentication.

With the inclusion of a feature that continuously captures palm vein images, instantly pick out the best image for authentication, and automatically verify, users can easily perform authentication by simply placing their palm lightly over the sensor.

To enable biometric authentication to be utilized in a wider range of locations and circumstances, Fujitsu has sought both robust security and superior user-friendliness for its palm vein authentication technology. At the same time, it also aims to develop smaller, thinner sensors that can be incorporated into a variety of electronic devices.

Fujitsu has worked to develop and commercialize thin, miniature sensors capable of being integrated into the design of notebook PCs. However, in order to make the technology readily applicable to an even broader range of applications, there has been significant demand for even thinner and smaller sensors that maintain the same high standards of security and usability.

With an eye toward incorporating this sensor into a variety of electronic devices, Fujitsu has developed the world's smallest, slimmest and lightest vein authentication sensor among a multitude of vein authentication devices, including those for the finger or back of the hand. Moreover, to facilitate integration with older versions of PalmSecure and to help users migrate to the new technology, Fujitsu has ensured compatibility with older generations while preserving the same usability, including continuous image capture and automatic verification functionality. The key features of the new sensor are as follows:
