Just another simple idea in addition to the ID verification book already mentioned. Some banks I have worked for before use black lights to see if an ID is real or not. A lot of States have security items on the DLs and IDs that will react under the black light. Some other items do as well like US Treasury checks (TAX season is upon us) and I believe Travelers Cheques and Postal Money orders do as well, but I have been away from the teller line a while now.
Just a few other ideas as well. Black lights are cheap and they work good on a number of things. Some banks have them at each teller station to help with this. But again, only if the states you are needing to verify have security features that will react to a black light.
Good luck
