Soon, you won't have to carry around that fat wallet of your ANYMORE, because the next new thing is identification is tattoos. That's right, get inked once and you have all your information linked together. This info can be accessed by a simple scan just about anywhere you go.
At the bank, you scan and all your bank accounts are displayed automatically. Scan yourself at the self-checkout stand of your local grocery store and not only can you pay with your linked bank account, but you can also activate your personalized discounts and reward points.
If there is some criminal activity, suspects can be scanned and so can the victims. That way the case can move forward at a quicker pace, helping justice take its course.
Yes, there will be people trying to counterfeit, but it will be much harder than making paper money or stealing credit card information with wireless card readers.
The tat doesn't have to be visible either.
