I would be more concerned about the idiots in DC screwing up the database which would keep a citizen from working, but that issue was never really touched.
The reason why some wanted to remove the ID requirement was to allow new illegals (even after most get Z-visas) to continue to get jobs.
BTW, the Social Security number was never meant to be used for identification purposes. Like just about everything else from Franklin Roosevelt’s “New Deal” it has become more and more of a monster as time goes by...
As well you should. There is no such thing as an "unforgeable" ID card. The card will have to be linked to a database. Then the problem becomes one of data integrity.
Suppose some clerk in Washington accidentally were to change your database entry, marking you as deceased. Not only would you be unable to get a job; you would be prevented from boarding an airplane, opening a back account, or taking out a loan. How long would it take to correct the error? And how much would it cost you?
