What is the passport card?
The passport card is a slimmer, less expensive alternative to using a traditional passport (now called a passport book).

The passport card is not designed for air travel.
How much does the passport card cost?
The passport card costs $45 for first time adult applicants who have never had a passport book and $35 for first time children. If you already have a passport book, the cost is $20.
