If the amount of cash you are going through exceeds what the ATM can handle. Keep in mind, the current NCR model we are using has eight cassettes, each of which can hold around two thousand notes each. The typical denominations used would be: 100s or 50s, 20s, 5s, and 1s. Point being, that you can hold quite a bit of cash in one machine. You will hopefully be dealing directly with us and will offer you the best deal we can on the ATM hardware. We normally discount our EZcash software when a level of three or more licenses has been reached.
