You should have looked in the glove box instead of just grabbing the tag off the mirror and running.
Seriously though, there's no name on the hang tag, so you need the wallet card to prove it's being used by the right person. I've had mine for 20 years and never been challenged, but just in case. I tried to scan it but the printed card is white lettering on an extremely light violet. The name/address and tag number is black print, but that's all that shows in a scan.
