For the Satoshi 1/2
The dispenser can hold 2200 notes of a single denomination in each cassette, so 2200 of each denomination. However, our machines are rarely fully stocked (there is usually far less than 2200 of any bills in the machine at any time).
We utilize two different models of acceptors on our machines, one is a lot smaller than the other and capacities vary, the larger accepters can hold 2200 note total.
If higher capacity is required, we also offer the Genesis1 machines, which are expandable to hold a much higher capacity.
