I was asked? What is a "Passport" card ??????? A passport card is a wallet sized card that passport holders can get in addition to their passport. It is good for ground travel to and from Canada, and air travel within the USA. _https://www.usimmigrationsupport.org/passportcard.html_ (https://www.usimmigrationsupport.org/passportcard.html) The Old RidgeRunner
