When a cash deposit is made at a Smart ATM, we are able to place a $ symbol within the secondary transaction description, and the BSA program uses this to identify currency.  But shared branch network activity is different. Transactions via Co-Op national shared branching have the ability to include both cash and checks as part of the funds in. Adding a notation to the transaction records would be difficult at it's not a 1:1 correlation between funds in and the transaction. For that reason, we use the message file to pull out the current portion of the deposit for BSA.

On the ATM side, mixed deposits are not supported so the transaction itself will be either cash or check, not a combination. This allows us to add that indicator directly onto the transaction record.
