If you are in a big city, you can always find the ATM(自动取款机)without any difficulty. They provide(提供)convenience(便利)for us. They serve us 24 hours, 7 days a week.
But one of the biggest problems is the ATM safety. You'd better remember the following advice.
First, keep your ATM card well. Report lost cards to the bank right away.
Second, protect your PIN(个人密码)well. Don't give the number to anyone. Don't write your PIN on your card or keep it in your wallet. Don't use numbers that are easily identified, such as your birth date.
Third, never leave your receipt(凭条)behind. Shred receipts before throwing them away.
Finally, for your own safety, spend less time at the machine. Have your ATM card ready before you use the machine. Count your money later, not at the ATM.
