Abstract: Techniques are provided for addressing possible fraud and mistake scenarios in a system for electronically receiving check images from customers and for automatically initiating a deposit of funds into a customer account. An electronic analysis of a check may be conducted to retrieve a check identifier that may be compared against a limited number of previously deposited checks, allowing for faster real-time comparisons. The deposit may be soft-post of regardless whether it is flagged as a potential duplicate, because subsequent more thorough analysis may uncover false positives. Also, transaction and account information can be analyzed to determine if there is a possibility of a check kiting operation.
