not only is it a violation of privacy, but with the way the world is turning into '1984' at a faster pace than ever, this would be the tool of control.
if you go into petrol station, fill up, and go to pay for the fuel with your credit card, and cashier says that the machine has rejected your card, what do you do? you say no problem i've got some cash, and you pay it that way.
what happens, when there is no cash, and the only way you can pay is by that electronic card? you have no choice. with cash there's only you who can control it. with electronic cash you aren't in control, someone else is.
just another step to the fascist new world order, and it wont be long before it happens.
'To achieve One World Government it is necessary to remove from the minds of men their individualism, their loyalty to family traditions and national identification.'
