ATM

Automated Teller Machines are everywhere for getting cash. ATM's can be modified to be more user friendly and able to make more money from costomers.

Deposits
By having a change slot where ATM card holders can make deposits with change from a change shoot, banks can get more money and users can save extra change they may have. Banks could rake a certain percentage of the change to make some money for non-bank ATM users.

Withdrawls
By having a extra change slot users can withdrawl an exact amount from the ATM. So if they only want to spend 20.75 dollars, they would recive a 20 dollar bill and 3 quarters.
