If you use a passport, it'll take a lot longer to verify. For example, banks will photocopy your passport and verify the signature on it to ensure that it's correct. (Basically, there's an algorithm used to compute a 30 digit hash on the ID or passport, which is computed from the IDs content and a secret seed. Anyone can verify this hash easily with open algorithms and tools, but only the government can create them).
