I had to supply my SS card and birth certificate when I switched to an OH drivers license.
I started carrying two wallets a couple years ago, one a normal wallet in my back left pocket and another a key wallet in my front right pocket. I have a credit card and cash in each so if one were to get stolen/lost then I still have the other. The back pocket one has a spare truck, car and house key and the front one has the normal use set of keys as well as some keys for tool and gear boxes in my garage. I always try to carry two of either gear so the two wallets with two money stashes follows this rule.
