He cannot be honest, do his job and still make a choice. Either the ID meets the requirements according to his knowledge, or it does not. The determination of validity flows from the facts and his knowledge, not a choice on his part. In this sense, he is operating as a machine, accepting input, matching it to criteria, and giving the resultant output. You would have to say the machine has faith and "believes" the ID is real. That either can be fooled is irrelevant.
He still has to have faith that no one has figured out how to forge the ID
For the rest of this, you are still using the word "faith" to cover many other terms. You would say I have faith that the sun will rise tomorrow. You probably personally do, as to you everything is faith. Back in reality it is a reasonable expectation based on experience and knowledge.
Sure he can. He can look at the ID and decide whether it looks real to him or not. That's a choice. He can also decide if the person standing in front of him looks like the photo on the ID despite changes in appearance.
Either the ID meets the requirements according to his knowledge, or it does not.
That's my point, he's making a decision, and that decision is based on a belief regarding the ID.
You would have to say the machine has faith and "believes" the ID is real.
Human beings are not machines.

I'm sure you have faith that statement is true. ;)
