The passport card is valid for land and sea crossing. So valid for border crossing to Mexico and Canada. If you are going on a cruise it can be used also. It is also another form of government issued ID that is not tied to a specific address.
We live 15 minutes from the Canadian border. The passport card is great since it can be carried in my wallet. I use it as my main form of ID whenever needed, including checking in for domestic flights.
