I agree with rlcarey... you're disclosing that the fee will be enforced beginning 6/1/15. You've met your requirement.
Do a quick analysis of how much it costs a teller to process a deposit. I've seen studies of true-cost of a basic transaction being in the $1-$2 range by the time processing, correction, proof, etc is all taken into account. Or, have the customer do that work, pay $0.30/item to your mobile capture provider, and your done. Charging a fee generates cost to your mobile RDC provider, but you save far more in efficiency gains.
