From what I saw in the link, the Passport Card is available if you’ve already had a passport. If you’ve never had one (like me), an Enhanced Driver’s Licence is easy to get. You bring your birth certificate to the DVM, they ask you a couple questions from it (where was your mother born, etc.), you pay an extra fee, and you’re good to go. I haven’t used mine yet to travel, so I can’t say how well it works.
(Since I was working in downtown Detroit for a while, I wanted the option of heading over to Windsor once in a while to see a show or concert. It never wound up happening, but it’s a nice thing to have, just in case.)
[Certificate, not verification. Autocorrect strikes again…]
