– Devan Antonito, Director, Wisemen IT Solutions
I purchased the .NET twain to deploy a document application to add new functionality in AziWin (the most important italian ERP for elevator industries). My feedback is very positive. The support team is quick to answer and happy to dive in customer problems.

– Emidio Rana, APSYSTEM
I actually purchased the .NET twain SDK and was able to rapidly deploy a document imaging/management application practically in a couple of days. I was on a very tight deadline to get this done and the thought of having to code a twain scanner app from a blank c# form was undesirable to say the least.
