Using your finger to navigate with the browser and on menus on a mobile phone usually means the phone has a touchscreen. But a new phone being used on NTT DoCoMo’s network in Japan has a different approach.

The new Fujitsu FOMA F906i phone uses technology from the fingerprint sensor company AuthenTec to turn the sensor into a touchpad with full navigation capabilities. It’s the first handset to use AuthenTec’s TrueNav technology.

The advantage, AuthenTec said, is that the sensor can be used for both fingerprint security and for on-screen navigation.

The F906i is the 16th Fujitsu handset to use AuthenTec’s fingerprint sensor technology. The 3G phone also has GPS, mobile TV, a mobile credit card and payments feature and VGA screen with two cameras.
