The embodiments presented within provide methods, devices, and systems that improve access control through the use of smart cylinder locks. In one embodiment, a smart cylinder may perform a process including receiving a key, emitting an energy source of electromagnetic radiation; detecting a change in the energy source due to a physical property of the key, determining the physical property of the key from the change in the energy source, comparing the physical property with a predetermined value, and engaging a mechanism operatively coupled to a locking device that allows the locking device to lock or unlock when the physical property matches the predetermined value.

Methods and systems relating to administration of access credentials for electronic access control are disclosed. Web resources are provided for rendering a webpage including an access credential. A server device receives an access instruction authorizing a user to access an electronic lock associated with the access credential. A client device of the user transmits a first request for the access credential. The first request may be generated by a browser application of the client device. The server device provides the web resources and a browser cookie to the client device. Responsive to subsequent requests for the access credential, the server device determines whether the client device is authorized to receive the access credential based on the client device providing the browser cookie. When the server device determines that a subsequent request authorizes the client device to receive the access credential, the web resources are provided to the browser application.

A method of controlling access through a door may include storing a user's digital identity and a user's access policy in a memory of the user's mobile device, which may use the stored user's digital identity and the stored user's access policy to determine whether the user is authorized for access through the door and to make an access decision of YES or NO. The access decision may be communicated to the reader, which controls operation of a door lock in accordance with whether the access decision was YES or NO.

Systems, apparatuses, and methods are provided herein for user access to smart locks at a retail shopping facility. In one embodiment, a system for user access to smart locks at a retail shopping facility includes an access member, a smart lock securing the access member, and a control circuit. The control circuit configured to receive authentication data from the user interface device; determine whether the authentication data matches within a threshold of stored authentication data associated with a profile stored in a database; determine that the user is a trusted user based on the determination that the authentication data matches with the stored authentication data within the threshold; and provide an optical key to the user interface device, wherein the smart lock is configured to unlock the access member in response to receiving the optical key from the user interface device.

An embodiment of an electronic access control system includes an electronic access apparatus, an electronic lock, and an access control administration program. The electronic access apparatus provides a wireless power signal and a wireless digital data signal to the electronic lock. The wireless power signal can be the only source of power used by the electronic lock to actuate an electronic lock mechanism. In some embodiments, the lock mechanism includes a piezoelectric latch.

This disclosure relates to the technical field of automobiles and discloses an automobile key programmer applied to an automobile diagnostic instrument, wherein the automobile key programmer includes an activation coil, a first changeover switch, a second changeover switch, an infrared modulation circuit, an amplitude shift keying modulation circuit, and a frequency shift keying modulation circuit; when the first changeover switch is not powered on, the infrared modulation circuit provides a resonant voltage for the activation coil; when the first changeover switch is powered on and the second changeover switch is not powered on, the amplitude shift keying modulation circuit provides a resonant voltage for the activation coil; when both the first changeover switch and the second changeover switch are powered on, the frequency shift keying modulation circuit provides a resonant voltage for the activation coil; only one coil is required in the automobile key programmer to change voltages.

It is provided a method for requesting remote unlocking of an electronic lock controlling access to a physical space. The method is performed in a user device and comprises steps of: sending a control message to an access controller, the control message comprising user authentication information, the control message causing the access controller to trigger the electronic lock to emit an alert signal; and sending an unlock message to the access controller comprising the user authentication information, in order to unlock the electronic lock.

An embodiment of an electronic access control system includes an electronic access apparatus, an electronic lock, and an access control administration program. The electronic access apparatus provides a wireless power signal and a wireless digital data signal to the electronic lock. The wireless power signal can be the only source of power used by the electronic lock to actuate an electronic lock mechanism. In some embodiments, the lock mechanism includes a piezoelectric latch.

Systems, methods, and apparatus for managing and controlling network-enabled movable barrier operators is provided. A method for managing network-enabled movable barrier operator includes receiving a user account identifier and a movable barrier operator identifier from a user device, providing an instruction to perform a specified action with a movable barrier operator associated with the movable barrier operator identifier to the user device, determining a registration condition is met upon detecting that the specified action has been performed, and, in the event that the registration condition is met, associating the movable barrier operator identifier with the user account identifier to allow a user account associated with the user account identifier to control the movable barrier operator over a network.
