Yes, a citizen of the United States can travel back and forth to Mexico using a U.S. Passport Card, as long as he does not fly in an airplane. You can travel by land or sea (on foot, by car, train, boat, etc.), but not by air.

The passport card was created to facilitate the frequent travel of Americans living in border communities. It can only be used for land and sea travel between the U.S. and Mexico, Canada, the Caribbean, and Bermuda.
A US passport card to use for travel to Mexico can be obtained in person at US Post Offices and by mail from the US Passport Agency. If you mean a Mexican passport card for use by Mexican citizens, that does not exist. Although Mexico has recently implemented a national citizenship identity card with fingerprint and iris scan biometrics, it cannot be used to enter foreign countries like a passport.
A Canadian citizen with a green card can use their Canadian passport to exit the US and use their US green card to re-enter the US under the same status. Hope this helps.
When traveling in the Northern Hemisphere, citizens of the U.S. can apply for a passport card to cross the boarders of Mexico and Canada and travel to the Caribbean and Bermuda. Travel can be by land or sea, but not for international air travel. The card is cheaper than a normal passport and is the size of a driver's license.
