What's the use of a dongle?
The main function of dongle is to prevent software piracy. Software developers encrypt their own software products with dongles, and then release them to the market. In this way, there will be no piracy in the short term, and they can protect their own commercial interests.
Today's dongle has the function of authorization, which can help software vendors to achieve a variety of sales modes and authorization modes. For example, for ERP software, different departments of an enterprise use different functions of ERP. How to make finance only use financial module and logistics only use logistics module? Can HR only use HR module? Different departments can only use the corresponding software functions through dongle or license authorization.
