What is one good thing about using technology that makes the Internet/World better?

[M.]

Given this dreadful tragedy of the lost plane, and the ever present concerns of identity theft, and passport theft, there must be a way of using technology to bypass this global problem. I would suggest, that people become micro chipped with relevant information, only they know. This can be upgraded over the years. This could also assist in the cases of children and people, who get lost, or brought to hospital unconscious etc.. It could be very iome saving and practical.
