When it comes to an ID, remember:

If you can make it, I can fake it.

The belief in perfect is what makes a forgery so dangerous. After the perfect ID, no one will verify as much. The object will seem certified. The path to failure is plowed by a perfect strong ID.

With a perfect ID in hand, you stop looking at me. I hand you an ID, you stop thinking and begin processing the ID. Open Sesame.
