The Federal Reserve Banks ensure that there is enough fit currency and coin in circulation to meet public demand. There was $888 billion of currency in circulation at the end of 2009. Using high speed machines, Reserve Banks processed 32 billion pieces of currency in 2009 and destroyed 6 billion pieces of unfit currency.
The Federal Reserve Banks process approximately one-third of the paper items that ultimately clear as checks in the country. In 2009, the Federal Reserve System cleared 8.6 billion checks, most of which were processed as electronic images.
The Federal Reserve Banks process electronic payments such as direct deposits of payroll, online bill payments, and large value transfers between banks. In 2009, Reserve Banks processed 11.2 billion electronic payment transactions, valued at $19.7 trillion, through the Automated Clearinghouse (ACH) payments system.
