A recent survey by TAWPI indicates that Remote Deposit Capture is delivering returns to FIs and corporates:

A whopping 78 percent of respondents to a recent TAWPI Question of the
Week say that their organization is receiving payback on its remote
deposit capture deployment.

Only 6 percent of the 86 respondents said
they weren't receiving payback, while 16 percent said they didn't know.
