For many applications, it is not the document or image but the data on that image that is important. For example on:
At SMS we have an experienced team of fully-proficient data entry clerks, both here in the U.K. and offshore, who can capture this data for you.
We can also design forms for automated data capture utilising Optical Character Recognition (OCR) or Intelligent Character Recognition (ICR).
When captured, the data can then be output in a variety of different formats, including delimited ASCII files, spreadsheets, Access or SQL database files, for onward analysis and data mining.
Of course if you want the scanned image kept, too, then all you have to do is ask!
