how is this any different from now? you apply for a job and you give them your drivers license number and your SS#. They could go look it up through the same channels.
I'm sick of people making the arguement that it lets them track everything in the world and that everyone would get access to everything on it.
Think about it for more than a second. Your SS# is usually tied somewhere to your health insurance; do you think that allows anyone working at your health insurance company to check out your passport status or your SS benefits (bad example that answer is 0 always...) ?
It's an ID that authenticates that YOU are YOU. It will do a hell of a lot of a better job than a SS# which you have no way of proving its your or not if it gets compromised stolen lost etc.
What they choose to connect with it is a seperate issue; just be sure to raise hell if they try to connect confidential information together that they cant.
This also doesn't mean that it would supplant your drivers license for everyday use; most likely it would start by replacing the horridly insecure usage of the Social Security number; especially since its highly likely that social security will fail any year now.
I fail to see any point which lets you make a logical jump from merchant swiping your id to see your old enough to buy beer to the merchant also seeing that you've been arrested 6 times for disorderly conduct.
Directly addressing your points:
what do you buy now that requires your SS#? next to nothing? Why would that change? Seems to me this would replace your SSN not your Driver's License. You don't have to be a citizen to buy things here.
Even if you did 'buy stuff' and have it checked; how does this information become the governments? They already check your ID when you fly anyways. You are making a huge jump that automagically a. it will always get logged to the government where and when your id is checked, and B. that without a warrant they will even be able to query such information. The only purchases you even mention are transportation based where your ID is already checked, whats the difference? make it such that all they can do is check that its valid and can't log that it was checked or where it was checked...
Your bit on crimes makes no sense at all. What does that have to do with anything? It doesn't matter how many crimes are given to you because thats unrelated and independent from this ID. All this does is make the background checks done by your company and police officers potentially more accurate and collaborated. It doesn't change when they may occur. You take a new job, they run a background check. What's changed here?
its rather simple, don't allow stuff to get stored that shouldn't be. don't allow people to access information they have no need for.
What freedom is being reduced? Can you name one?
There is nothing wrong with the card in itself, its the implementation and usage that you should be concerned and vigilante about. Until then, just keep staring at your SSN card.
