An ID card is a small card that shows who you are.
It has your name, photo, and sometimes your address.
In the United States, many people have ID cards.
Common types are a driver's license, state ID card, and passport.
A driver's license lets you drive a car, while a state ID is for people who do not drive.
A passport is for traveling to other countries.
These cards are very important for many things like buying age-restricted items or opening a bank account.
