Abstract
Methods and systems relating to administration of authentication information for electronic access control are disclosed. Authentication information is conveyed to an electronic locking device configured to restrict access to an entry point. In various embodiments, a smart device comprises a display screen for presenting a machine-readable optical code comprising encoded authentication information. An image sensor of the electronic locking device can decode the machine-readable optical code to obtain the authentication information. The electronic locking device is configured to permit access to the entry point in response to the image sensor detecting a machine-readable optical code corresponding to an access credential. A server device can provide authentication information to the smart device based on an access criterion. Conveying authentication information to the locking device may include rendering a webpage comprising the machine-readable optical code corresponding to the access credential.
