I think that it is rare for the ATM to give you more money than it was supposed to. It is almost always the other way around. I have heard of so many cases where ATM didn't give out the money or it gave less. My sister once got $50 less than she should and she realized it only when she got back home. The people in the bank didn't believe her and she couldn't do anything about it. ATMs are helpful machines, but they are having problems sometimes. If all the ATMs were using quality materials these things would not happen. You can click here to check out the best ATM equipment.
