Once your paper documents are scanned someone will type into the index fields the appropriate data. This data can be automatically captured in some cases. If you have control over how this document is created, whether your own in house documentation or another agencies, you can request to apply bar codes on the front or back side of the document. We have used bar codes from the beginning, helping our customers save a lot of labor costs and increase accuracy. Bar codes are simple to implement and relatively low cost to own and maintain.
