Communications with no barriers - is that a blessing?

Talking about the future of communications - how about a "touch sensitive" sensor device that is able to take orders from the user individual and enable electronic payments or data transfer at the touch of a finger? This is just one example.

The excitement about future communications is more than just a cool new mobile phone. It will be about removing the barrier between people and devices/gadgets. The human body will quite gradually and literally become part of the human-electronic interface. This may sound pretty far-fetched but how about doing without the keyboard and attaching sensors to each finger such that any deliberate movement of your fingers will translate into action? For example, tapping a code-like motion with your fingers to instruct a device to access the Internet, take photos and take/send messages.

This will sound more unbelievable - using your human finger to simulate the receiver function of a phone. When you hear the phone ring next time, insert your finger into your ear and start speaking into a "module".
