A method for operating an access control comprises creating a plurality of wake-up schedules for a wireless transceiver. Each of the plurality of wake-up schedules may be configured to control how frequently the wireless transceiver wakes up to transmit or receive information. Each of the plurality of wake-up schedules for the wireless transceiver may be different from another one or the plurality of wake-up schedules for the wireless transceiver. The method may further comprise automatically switching between the plurality of wake-up schedules for the wireless transceiver such that a duration of time between wake-ups for the wireless transceiver radio is shorter during some predefined times and longer during other predefined times. The duration of time between wake-ups for the wireless transceiver may be configurable by an administrative user via an interface.

An access control system and a method performed therein, for handling access to an access-restricted physical resource. The method comprises, by means of a first credential reader, receiving an initiating access request credential initiating a request to give one or more visitors access to a first access-restricted physical resource. The method further comprises, by means of the first credential reader, receiving a visitor credential for each visitor for which access is requested, and, by means of a second credential reader, receiving a finalising access request credential finalising the request to give the one or more visitors access. Furthermore, the method comprises, by means of a first resource controller, allowing a visitor to access the first access-restricted physical resource upon presenting the visitor's visitor credential to the first credential reader.

Multiple portable electronic devices within an exemplary system functionally cooperate amongst themselves to access a remotely controllable device. These portable electronic devices execute exemplary prioritization routines to identify a preferred portable electronic device from among the portable electronic devices to access the remotely controllable device. Thereafter, the exemplary system transfers ownership of a software implemented access token to the preferred portable electronic device to allow the preferred portable electronic device to access the remotely controllable device.

Electronic systems are provided for secure actuation of a remote device such as a moveable barrier operator. The systems address the “man in the middle” problem of persons intercepting and duplicating radio frequency signals from a control device by introducing timing parameters into a bidirectional communication sequence between at least two devices.

A transfer key system for a vehicle may include a key receptacle configured to detect the presence of a transfer key, and a controller configured to receive key status signals from the key receptacle, and activate the transfer key as an active transfer key in response to the status signal indicating a removal of the transfer key from the key receptacle and receiving an authentication signal from a user.

A trainable transceiver for controlling a remote device includes a transceiver circuit configured, based on training information, to control the remote device, a communications device configured to communicate with a mobile communications device, an output device, and a control circuit coupled to the transceiver circuit, coupled to the communications device, and coupled to the output device. The control circuit is configured to receive notification information from the mobile communications device via the communications device, and wherein the control circuit is configured to generate an output using the output device based on the notification information.
