Abstract: The device controls the opening and closing of mechatronic access control barriers. It validates entry requests from identity verification mechanisms with a real-time database of authorizations. Controlling users can give, remove, and edit virtual entry keys in real-time. Keys are programmed for one-time use, specific amount of uses, or in a fixed or recurring schedule. Potential guests can request in advance a virtual key of a restricted area from controlling users. The device sends an entry notification to controlling users when their virtual keys are used.
