The transponder unit is designed to transmit, in a first operating state, to the transmission unit, in response to the request, a reply containing the motion information, wherein the transmission unit is designed to decide on the basis of the motion information whether to activate the object.

The present disclosure discloses an electronic work card, a control method and device thereof, a storage medium and an attendance management system. The electronic work card includes: a controller and a Radio Frequency Identification (RFID) device; wherein the RFID device is configured to identify at least one actuator in the environment, receive the identification information provided by the at least one actuator when the at least one actuator is identified, and send the trigger information to the controller; the controller is configured to obtain the identification information of the actuator after receiving the trigger information of the actuator, determine whether the electronic work card is in the preset workplace according to the identification information, and in response to determining that the the electronic work card is not in the preset workplace, control at least part of the functions of the electronic work card to enter the non-working state.

Provided are an electronic device and an operation method thereof. The electronic device may include: first and second antennas to receive a signal output by an external electronic device; a communication circuit configured to control the first antenna and the second antenna; and a processor. The processor may be configured to: receive the signal through the first antenna and the second antenna; measure a first distance between the first antenna and the external electronic device using the signal received by the first antenna; measure a second distance between the second antenna and the external electronic device using the signal received by the second antenna; determine a movement direction of the external electronic device based on a change in a difference between the first distance and the second distance; and perform a preset operation corresponding to the movement direction of the external electronic device. Other embodiments are also possible.

A method and a tag for opening a powerless electromechanical lock are provided. The tag comprises a power source, a near field communication transceiver, an antenna connected to the transceiver, an proximity switch and a controller. The switch is configured to wake up the controller from a low power mode upon a detection of a predetermined signal. The controller is configured after the wake up to activate the near field communication transceiver and control the transceiver to transmit via the antenna wirelessly first operating power to the lock for communication and authentication, perform authentication with the lock and, provided that the authentication is successful, control the transceiver to transmit wirelessly second operating power to the lock for the lock to be set into an openable state.

An entry system includes a transponder unit and a transmission unit which is arranged in an object. The transmission unit is designed to transmit a request to the transponder unit, and the transponder unit includes a motion sensor which is designed to detect a movement of the transponder unit and to generate motion information. The transponder unit is designed to transmit, in a first operating state, to the transmission unit, in response to the request, a reply containing the motion information, wherein the transmission unit is designed to decide on the basis of the motion information whether to activate the object.

A terminal performs communication with an in-vehicle device to control a vehicle. The terminal includes a controller configured to switch and set a plurality of operation modes, and a vibration detection unit configured to detect vibration of the terminal. The operation modes include a first mode, a second mode different from the first mode, and a third mode where communication with the in-vehicle device is more restricted than in the first mode and the second mode. The controller is configured to, when the first mode is executed, in a case where vibration is not detected in the vibration detection unit for a predetermined time, switch the operation mode to the third mode, and when the second mode is executed, in a case where vibration is not detected in the vibration detection unit for a time longer than the predetermined time, switch the operation mode to the third mode.

A method and a device are provided for non-mechanical activation of a closure arrangement, in particular of a vehicle door, by way of a mobile terminal. The mobile terminal is registered and corresponding registration information is generated, on the basis of which an activation signal is transmitted to the registered terminal. The terminal changes from a first operating state into a second operating state on the basis of the activation signal, wherein in the second operating state a user input is registered by way of the terminal, and corresponding input data are generated. An activation signal which is output by the terminal operated in the second operating state, on the basis of the input data, is received, and the closure arrangement is activated in a power-driven fashion on the basis of the activation signal.

A system includes a processor configured to generate a new access key, responsive to a vehicle shutdown. The processor is also configured to connect to a previously identified user wireless device. The processor is further configured to deliver the new access key to the user wireless device, responsive to connection to the wireless device and locally store a copy of the new access key in a file designated for reference for a next-access attempt.

Aspects of the subject disclosure may include, for example, a device in which a processing system of a remote entry system selects a first circuit from a plurality of circuits of a key remote from the device; wirelessly transmits a first challenge signal to the key, the first challenge signal specifying the first circuit; and wirelessly receives a first response signal from the key, the first response signal having a first response signal power level and a first response signal delay with respect to the first challenge signal. The processing system analyzes the first response signal by comparing the first response signal power level and the first response signal delay respectively with a predetermined first signal power and predetermined first time delay associated with the first circuit; and, in accordance with the comparing, determines whether to enable the entry system. Other embodiments are disclosed.
