KDDI introduces app that authenticates you after reading your palm
Biometric scanning is the thing of the past. Now scan-based authentication should be more available to everyone. Just what KDDI made possible with their all new palm scanning application. This app makes use of high-resolution cameras at the back of phones to store your palm information and later use it as a means to unlock your phone. You have to simply place your hands between two red markers that trace the boundary for you. Then your screen is locked and can be unlocked only by placing your palm before the camera.
Engadget tried it out and it worked perfectly. Of course, one cannot expect the authentication process to be faster than entering a secret numeric code.
