With KleverKey you are free to send your guests online or offline permissions. However, there are permissions that require an online usage.
When you are sending a permission with attribute "Online usage", the App will check the permission real-time with the KleverKey Cloud (while using the permission).
Therefore, the Smartphone will need internet connection during usage of a permission and a bit more time to process.
Certain permissions may force "Online usage", e.g. when the permission is time-related or limited. Those permissions will always check the expiration with our Cloud.
Remark: Permissions with "Online usage" requires Android V3.6 and iOS V3.0 or newer.
If you are sending a permission without the "Online usage" attribute, the App will not explicitly check the permission at the time of its usage and thus, it can be used more flexible (e.g. in a cellar or in situations where no internet connection is possible).
Offline permissions can be used for Always permissions and will be processed faster than online permissions.
