Printed questionnaires should be manufactured on machine-readable paper and analyzed by scanners that are capable of Optical Mark Recognition (OMR) or Optical Character Recognition (OCR) to convert the results into a digital format that is automatically placed into a database for storage. Queries can then be utilized to poll or collect information from the questionnaires. Telephone surveys should consist of precise questions that require simple answers that can be input by pressing buttons on a touchtone phone. Users who do not have a touchtone phone should be allowed to answer verbally via an interactive voice recognition system (IVR).
Bank checks should be printed on machine-readable paper utilizing magnetic ink such that machines can quickly and accurately scan the document and convert the data into a digital format. Additional security measures such as watermarks and holograms may be utilized based on level of se...
