How to use an ATM
Automatic teller machines (ATMs), or cash machines as they are commonly called, are the most convenient method to access cash in the US. To use the machine you must have an ATM card for your bank account or other credit card. The machine will allow you to withdraw money from an account or charge against your credit card. Your credit card might start charging interest on the money you withdraw right away, instead of giving you the typical 30-day grace period for purchases, so check your card's rules before using.
