Answer:
It's certainly not Federal law, and I doubt that a state would impose such a requirement. That leaves the possibility that one of the networks that your ATM accesses has an operating rule that requires it. Check the operating rule or network contract. If you don't find anything there, tell the processor that unless there's documentation of the requirement, you won't open the ATM to interchange deposits.
Remember, the processor works for you, not the other way around.
