A system for accepting documents and handling the data contained therein includes a reader and digitizer for producing and storing fragmented or digitized images simulating the characters and graphics on the document. Each document is marked with a unique identifying code. Selected portions of the data are converted to a machine code and stored and portions of the digitized material are also stored. Converted and unconverted segments can be recalled for complementing and verifying the machine code. Access is available to either in storage.
