A method and apparatus are used to provide quality assurance for the electronic transfer of document image files, for example, between banks. The documents may be, in the case of a bank, negotiable instruments, checks, deposit slips or other transactional documents. The document image file contains an image tag file and associated image data file. An image tag file contains first quality assurance data. An image data file contains second quality assurance data. The quality assurance data may be a MICR line from the document. A first reader extracts the first quality assurance data from the image tag file. A second reader reads the second quality assurance data from the image data file. A comparator receives the first and second sets of quality assurance data from the first and second readers and compares the first and second sets of quality assurance data to find correspondence between the data. The level of the correspondence provides an indicator of the quality of the image data file and associated image tag file data.
