All TWAIN Data Sources and applications have a TWAIN Identity. This enables the TWAIN Data Source Manager (DSM) to keep track of all running TWAIN applications and Data Sources.

A TWAIN Identity consists of four strings: Product Name, Product Family, Manufacturer and Version Information.

These identities can be set for TwainPRO applications using the ProductName, ProductFamily, Manufacturer and VersionInfo properties respectively.

These properties are part of TwainPRO Session Initialization so they need to be set before calling the TwainDevice.OpenSession or TwainDevice.StartSession methods.

Some Data Source User Interfaces will display a progress indicator during image transfer that displays the application's Product Name Identity.
