Patent number: 12039504Abstract: Methods and systems for remote check deposit are disclosed. A check image captured by an image capture device of a mobile device in response to receiving a user actuation causing the image capture device to capture the check image is received. The mobile device is caused to perform optical character recognition (OCR) on the check image to generate OCR data. The OCR data generated from the check image is verified to determine whether it includes required predetermined check data to process the check for remote deposit. The OCR data is provided to a financial institution server for validation processing. In response to receiving a confirmation from a user, the check image is provided to the financial instruction server with instructions to process the check for remote deposit.
