Dongles make it easy to create demo versions of software products without writing a separate demo version of the application. Copies of the application can be distributed free of charge while blocking or limiting certain application features that can be unlocked only with a dongle.
Use of dongles with a battery and RTC makes it possible to install fully-functional versions of software products for potential customers with usage time limitations. In this case, the user can switch from a trial version to a fully-functional version by having the dongle reprogrammed remotely, with the results of previous application usage retained.
The licensing wizard included in Guardant SDK offers the developer a convenient interface for limiting the features of the protected application:
- Blocking of individual modules from starting;
- A limiting counter or a limited number of launches.
With Guardant API, the developer has boundless opportunities to create application versions with limited functionality.
