After Neo-Nomad's Tatoo, there is another way to connect body and mobile blog: use your fingerprint for (almost) everything:

• Security - the most reliable and accurate form available. It excels in conveniently protecting personal images and data, as well as secure authentication for m-commerce and wireless banking.
• Convenience - security and control at the touch of a finger. Touch controls make security practical, and make nearly any application easier to use.
• Full navigation capabilities - similar to a joystick or scroll wheel. Easy navigation for gaming or map based location applications .
• Personalization features such as multifinger speed dialing and buddy list controls.

Many carriers, such as Japan's NTT DoCoMo, are recognizing that current biometric sensors in place on a growing number of PDAs provide an excellent touch-pad surface, allowing the finger that authenticates to become a mouse, for optimal navigation.

"This is going to make a big difference for Web browsing on a phone as well -- and the technology is well on its way," said a spokeswoman for AuthenTec, an international technology developer for the mobile market.
