I'd like to use something like this to verify that my credit card statements are accurate. I don't want to give an app access to my bank logins (as I believe Mint requires). So I envision a workflow where I snap receipts, the app digitizes them and produces a transaction list which it either compares against a monthly statement PDF, or I do the verification by hand. Anyone have a good, established workflow for this?
