  • Publication number: 20240355163
    Abstract: It is provided an electronic lock for controlling access to a restricted physical space. The electronic lock comprises: a first credential interface for accepting a credential from a user for evaluating whether access for the user should be granted; and a second credential interface for accepting a credential from a user for evaluating whether access for the user should be granted. The first credential interface is configured to be activated when the user causes an interaction with the first credential interface, without activating any other credential interfaces. The second credential interface is configured to be activated when a user causes an interaction with the second credential interface, without activating any other credential interfaces.
