Cash and How We Use It: What Is Cash, US Currency, Coin, Money

You have several options for how you pay for products and services using cash, debit cards, credit cards, checks, and now mobile services on smartphones.

Although some of these payment methods have become more prevalent than cash for everyday transactions, cash still plays an important role in our nation’s economy and in the global marketplace with more than $1 trillion of U.S. currency in circulation around the world.

The Federal Reserve works closely with our partners in the Bureau of Engraving and Printing, the U.S. Mint, and the U.S. Secret Service to maintain public confidence in the quality of currency and coin in circulation.

In this section, we will explore the history and evolution of U.S. currency and coins and share information on design features and security measures that help us ensure the integrity of the cash you use in your daily life.
