TeamViewer employs an approach that merges usage pattern analysis with license key verification to distinguish between personal and professional use. It tracks aspects like the frequency, duration, and quantity of concurrent sessions, which are evaluated against the thresholds of the free (personal) version. When usage surpasses these thresholds, the system alerts users to obtain a commercial license. This automated identification guarantees that companies invest in the enhanced features necessary for professional purposes while maintaining the personal version at no cost.
