Passport card

The passport card (previously known as the People Access Security Service Card, or PASS Card) is an alternative to a passport produced in the United States to meet the documentary requirements of the Western Hemisphere Travel Initiative. The U.S. Passport Card is a wallet-size travel document, issued to U.S. citizens and non-citizen nationals, that can be used to enter the United States from Bermuda, Canada, Mexico and some Caribbean countries at land border crossings or sea ports-of-entry and is more convenient and less expensive than a passport book. The passport card cannot be used for international air travel.
