Imagine you arrive at your favorite club or bar and when they ask for your ID they run it thru a scanner that is linked to a database. I have nothing to hide but that kind of personal intrusion gives me the creeps and would be very prone to abuse. The company that is making it says it can be used to build demographics etc.
I can see were this would also be a law enforcement dream in that you get arrested for something and they will know exactly were you have been that night if you have been out bar hoping or have been a specific club for a long time which depending on the charges that have been brought against you could be used in a court of law.
With identity theft already at a all time high there is no way I am allowing my id to be scanned into a some central non government controlled database. [Engadget]
