A smart card with a fingerprint sensing system, includes a controller and a fingerprint sensing device. When the fingerprint sensing device senses a fingerprint to generate a fingerprint frame data, the controller enters a sleep mode, and when the controller reads the fingerprint frame data, the fingerprint sensing device stops sensing the fingerprint. Since operations of sensing the fingerprint and reading the fingerprint frame data do not occur at the same time, the high current condition can be avoided so as to decrease power consumption.

Methods and apparatus to adjust an advertising rate of a device to reduce battery usage are described herein. An example method includes determining a distance of a device from a vehicle based on a signal, determining a state of motion of the device, and adjusting an advertising rate of the signal based on the distance and state of motion.

An information processing device relates to a predetermined service provided to a user by allowing a worker to temporarily access a vehicle cabin including a trunk of a vehicle used by the user. The information processing device includes a processor. The processor is configured to determine whether the worker relating to a service provider of the service has unlocked a door of the vehicle using key information for unlocking the door, the door accessing the vehicle cabin of the vehicle, and notify the user of a warning or activate an alarm device of the vehicle, in a case where the processor determines that the door has been unlocked and in a case where the processor determines that a state in which the door of the vehicle is not locked continues after a predetermined time has elapsed from unlocking of the door.

A key, a lock core and a lock, relating to a key, a lock core and a lock are provided. The key includes: a column body, a first end of the column body being provided with a light emitting component; a first cathode component disposed on the column body and connected to one end of the light emitting component to be mated with a second cathode component in the lock core; a first piezoelectric electrode disposed on the column body and connected to the other end of the light emitting component to be pressed against a second piezoelectric electrode in the lock core. When the first cathode component is mated with the second cathode component in the lock core, and the first piezoelectric electrode is pressed against the second piezoelectric electrode in the lock core, a piezoelectric current is generated, to cause the light emitting component to emit light.

An access control system having one or more system antennas that are configured to emit a first signal having a first frequency that is detected by the credential device. The credential device is configured to harvest electrical power from at least a portion of the detected first signal. At least a portion of the harvested electrical power may be used by the credential device to transmit a second signal to a reader device, the second signal containing information indicative of a credential stored on the credential device. Further, the second signal has a second frequency that is different than the first frequency of the first signal. The reader device and/or a server may evaluate the transmitted credential to determine whether the credential is associated with an authority to operate the reader device, such as, for example, an authority to unlock a lock mechanism of the reader device.

A system and method for energy saving on access control products is disclosed. An access controller controls access control readers, which in turn enable access to a building and/or interior areas of the building. The access controller can identify the locations of the access control readers relative to the building, such as whether the access control readers are located on the perimeter of the building for controlling access to the building, or whether the access control readers are located within the building for controlling access to interior areas of the building. The access controller can then place one or more of the access control readers into a power saving state without compromising overall building security, such as placing interior access control readers into a power saving state when the building is assessed to be unoccupied.

Systems, devices, and methods are disclosed for unlocking a vehicle. An example vehicle includes a power system, a remote unlock system controlled by a remote unlocking device, and a door applique. The door applique comprises a wireless charger coupled to the power system, configured to charge the remote unlocking device, and a ridge configured to engage the remote unlocking device, wherein the wireless charger is configured to charge the remote unlocking device for a limited time.
