Actually, as I understand it, the technology is there to support a national ID card. It would be similar to the chips that are implanted in some credit cards. An example of info it would contain: thumb print, blood type, DOB, SS#, criminal record.
The card would be used in conjunction with a scanner that would "read" your thumbprint and compare it to the info on the chip. I'd have to think that the government could implant some type of "signature" in the chip to prevent the cards from being faked.
I think that there will be a large push in Congress to get this done but, ultimately, the cost would be prohibitive.
