At a recent gathering of regulators, lawyers, and bankers in N. Texas, the general consensus was that this is not a good idea.
The difference between in-person and RDC deposits is that when they give me the physical check, I keep it. With RDC, they scan the check and keep it themselves. MSBs are already high risk customers...why offer them a high risk product as well?
I personally won't allow it. Just not worth the aggrevation.
