Banks and most retailers actually have a book with photos and details of various security aspects of the license and ID cards in-use.  For fun, I have presented my "Global Entry" ID card at the bank for a transaction to see if they had seen it before.

The US Federal Government tried to standardize on HSPD-12, now about 5 years old.

Making a secure document, or something that uses PKI such as this is harder than it may initially seem.  This is why I'm not the one designing them.
