I can only think of 1 BSA related issue and 1 non-BSA issue.
BSA - If you're an OCC bank, the MLR instructions say that the numbers you provide for RDC can't include mobile.
Other - if you want to be able to track your mobile transactions vs. RDC, does your system provide reports or would you have to rely on a tran code?
