"In developing our image viewer and scanning solution, a significant concern was to quickly have an ability to support multiple browsers in Windows and Mac. We also didn't want to have to worry about the challenge of staying ahead of browser updates whenever they happen. These were the primary reasons we chose to use Dynamsoft's Dynamic Web TWAIN SDK and it has delivered."
