ID Charge

I wonder if there's a way to tie a specific credit card to a driver's license? Obviously the DMV would have to get involved but there's information on that stripe...so why couldn't we put more on there? I know it isn't a big deal to carry two cards if you're already carrying one, but it might make a difference. Stashing one card certainly might be easier (you know, if you're trying to hide it.) And if you lose it? It's now worse than if you lost or the other. Actually it might be more secure since your picture is right there.
