A Japanese company creates a biometric app that utilizes the existing camera on the mobile.

At the recent CEATEC conference in Chiba, Japan, mobile manufacturer KDDI revealed its latest app that allows a user's palm print to unlock a phone. The authentication app uses the existing camera on the smartphone to ‘scan' the unique palm print. The user simply needs to hold out their hand for a few seconds before they're presented with an onscreen unlock button.

KDDI believes that this technology will provide a higher level of security compared to the current method of entering PIN codes. Nevertheless, a palm scanning app could be of an inconvenience during colder weather when people have their gloves on.
