I'm doing the Google searches now. I specifically remember a suit brought against a college for using the SSN as an identifier. The problem is, I don't have access to the legal case search system.
Sure enough that abuse has occurred, despite heroic efforts to combat it.
While the damage done to privacy by SSN's was profound and unprecedented, it pails in comparison to the potential for abuse posed by these chips. IMO, the RFID is one of the most powerful data gathering devices ever invented. Today we are told we are in a post 9-11 world, and "everything is different" meaning security is paramount above all other concerns.
In light of this, why should we believe chips won't be abused?
I believe that there were suits against having the SSN on driver's licenses as well
However, you need your SSN to open bank accounts and get bank cards and get a morgage and stocks and bonds. You probably don't need them to get a gas or store card. but, try renting a car with cash.
