  • Publication number: 20240404337
    Abstract: A system includes a server having a communication device and a processing circuit. The communication device is configured to facilitate communication with electronic devices. The processing circuit is configured to receive permission from a first user device for a guest user to access an electronic lock using a second user device, provide a notification to the second user device regarding a guest user profile, receive an activation command from the second user device based on the notification, generate the guest user profile for the guest user in response to receiving the permission and the activation command, and transmit the guest user profile to the second user device. The guest user profile is usable to allow the guest user to unlock the electronic lock.

  • Publication number: 20190003206
    Abstract: Embodiments provide a lock including an actuator that is movable between an unlocked position and a locked position, and a bolt that is movable between an extended bolt position and a retracted bolt position independent of the position of the actuator. In the extended bolt position, the bolt extends outside a body of the lock. A coupling element is arranged between the actuator and the bolt and is movable between an extended coupling position and a retracted coupling position in response to movement of the actuator between the locked position and the unlocked position. A first biasing element biases the coupling element toward the retracted coupling position, and a second biasing element couples the coupling element to the bolt and is structured to bias the bolt away from the coupling element and towards the extended bolt position.

  • Publication number: 20160036788
    Abstract: Disclosed are methods, and devices for wireless key management for authentication. One method includes receiving a lock identifier from a locking device; determining that the lock identifier is associated with a user profile, wherein a user profile is authenticated and encrypted by a server using a lock key that is stored by the server and the locking device, and wherein the user profile comprises a user key; transmitting the user profile; decrypting the user profile using the lock key; transmitting a security code; generating an encrypted command comprising the security code and encrypted using the user key; transmitting the command; validating the command. Validating the command can include decrypting using the user key; determining whether the security code is valid; and authenticating using the user key; and initiating, in response to validating, an action of the locking device as specified by the command.

  • Publication number: 20130335199
    Abstract: Systems and methods for use in detecting the presence of an RFID device are provided. One RFID detection system includes a detection circuit that includes an oscillating circuit. The detection circuit is configured to hold the RFID detection system in a low power mode in which the RFID detection system is configured to not actively attempt to communicate with nearby RFID devices. The detection circuit is further configured to monitor one or more parameters of a signal of the oscillating circuit and compare the one or more monitored parameters to one or more reference parameters. The detection circuit is further configured to, based on the comparison, determine whether to transition the RFID detection system from the low power mode into an active communication mode in which the RFID detection system is configured to actively attempt to communicate with nearby RFID devices.
