And it's actually better than what they usually have in groceries for beer and cigs - they have stickers that they change annually, and the cashiers probably need to do a visual check first. I don't see their screen, though, and I somehow don't get carded anymore :), so I can't really know what they see when they type the DOB. I figure the above check will more than suffice.
