Technical software is usually sold with a physical ‘key’ that has to be fixed on a computer for unlocking the software and make it available for use. SML Software security is assessed not by using a ‘physical key’ but using instead an ‘online key’ (username - password). Access and validity of the user license is checked online.This means that the user must have an internet connection for entering its Username and Password. Then AKTS servers automatically check the validity of the username and password (license validity) and give the authorization for software use. Once logged the software can then be used offline. This online feature makes possible that the users get access to the latest update. For all users who have the annual maintenance package, all updates are FREE of charge and give access to the latest version with the latest features.
