Remote deposit capture for the gaming industry

A remote deposit capture system for distributed processing of check presentation can sense, or be instructed to differentiate, between deposit document types, including checks, cash withdrawals, and casino markets. Thereby, automated recognition and correction features can be selectively applied to an imaged deposit document. Thereby deposit documents that tend to use identical transaction codes, such as the same routing/transit numbers in magnetic ink character recognition (MICR) code line data, can be effectively processed without a high failure rate due to duplicate detection. Yet the advantages of duplicate detection are still leveraged against other deposit types. Alternatively or in addition, duplicate detection can be selected to not depend upon uniqueness of MICR code line data.
