What is the investment necessary to build up a computer aided data entry system?

For simple tasks where only a few thousands of forms must be read containing ten check boxes in some rows and one bar code for the identification, the price will be about EUR 1,200 to 2,000 together with a proper, one-sided entry-level scanner.
The majority of the typical OcuLens projects are about 10,000 to 30,000 Euro-s (including the scanner’s cost).
Projects for large companies with several sites and high performance scanners may mean an expense of a few ten thousend Euro-s.
