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