Read full descriptionHide full description
The UnitTwain client enables you to take pictures on your mobile phone and then import them to any TWAIN compliant application on your PC. Install the UniTwain server component to your PC and then start your application and select the UniTwain virtual scanner. Once UniTwain shows up select the Mobile tab and start the UniTwain client on your phone. Now just take photos or choose them from your gallery and they will automatically show up on your PC application. You can also select the scanning option inside the UniTwain client. This way you can take pictures of documents on your table and the UniTwain client will automatically crop out the the surrounding and enhance the document so that it looks as it came right out of a scanning device.
