Kudos to Avis
I happened to look recently at the little card that Avis puts in the cars of frequent renters. The idea is that you land, get to Avis, see your name on a board, and walk directly to the car with one fewer line to stand in. So as you drive away, the fellow who checks your license against the car gets a little bit of paper with your name, your drivers license information, and some car information. The cool part is that your drivers license number is printed as state of issue, a series of Xs, and only the final four digits are shown. I was pleasantly surprised.
