Abstract: Methods and systems for operating a switching device are described herein. A switching control component on a server may receive a URL request that includes a unique ID from an NFC token proximate to the switching device. The switching control component determines if the URL request includes valid login data, and when valid login data is detected for a user with permission to access the door associated with the NFC token, a message to the switching device with instructions to open the door may be transmitted. When the URL request includes valid login data for a user without permission to unlock the door, a selectable list of users who have previously granted the user access to the door may be transmitted. Finally, when the URL request does not include valid login data, a URL may be sent providing a tap-to-unlock application download message and at least one alternative access option.

Abstract: Systems and methods for controlling a barrier are disclosed in which a barrier control component running on a server receives a first key and a request from a user device to provide a second key and a set of abilities to a second user device. The barrier control component retrieves information associated with first key, with the information indicating whether or not the first key is authorized to provide the second key and the set of abilities to the second device. When a review of the information regarding the first key indicates that the first key is appropriately authorized, the barrier control component provides the second key to the second device, and stores the set of abilities associated with the second key.
