For a definition of RDC, please see http://www.remotedepositcapture.com/overview/rdc.overview.aspx . Here's an excerpt...
Remote Deposit Capture, in its most simple terms, is a service which allows a user to scan checks and transmit the scanned images and / or ACH-data to a bank for posting and clearing. The basic requirements for an RDC service currently include a PC, an internet connection, a check scanner and a service provider such as your current bank. Checks you receive at your corporate or bank location can be scanned to create a digital deposit. This digital deposit is then transmitted (usually over an encrypted internet connection) to your RDC bank or service provider who then accepts the deposit, posts the deposit to your account and assigns availability based upon your availability schedule.
Remote Deposit Capture often has different names depending upon how the service is applied within a particular environment. These names include “Corporate Capture”, “Merchant Capture”, “Image Deposits”, “Image Cash Letters”, etc. In general, we see the term “Remote Deposit Capture” increasingly used as the catch-all phrase for a family of related products and services. Each of these service family members are related in 1 common way: The service allows for checks to be truncated and cleared electronically.
I'm not sure there is an offiial term / definition for R-C-D.... it often is simply an attempt at unique branding. Comparable terms we've seen include "Distributed Capture", Electronic Check Deposit, etc. Each person might have a different understanding of each dfferent term. This is why we set out to establish an official definition for Remote Deposit Capture - so we could all at least speak the same language.
