摘要： Various systems and methods for providing discovering smart card slots in a device are described herein. A server device for discovering smart card slots in a client device may be implemented with a processor subsystem; and memory including instructions, which when executed by the processor subsystem, cause the processor subsystem to perform operations comprising: receiving, at the server device from the client device, over an established Bluetooth connection, smart card connector parameters, the client device having a plurality of smart card slots; iterating through the plurality of smart card slots; at each slot of the plurality of smart card slots, using a smart card protocol to attempt to access an application at each slot, the application pre-associated with the server device; and in response to identifying the application exists in a slot of the plurality of smart card slots, connecting with the application.

摘要： Systems and techniques for a physical access control systems with localization-based intent detection are described herein. In an example, an access control system may regulate access to an asset. The access control system is adapted to receive a credential for the asset from a key device associated with a user using a first wireless connection. The access control system may be further adapted to store the credential in a cache of memory. The access control system may be further adapted to establish a second wireless connection with the key device. The access control system may be further adapted to request a validation of the credential from an authorization service in response to establishing the second wireless connection with the key device. The access control system may receive a validation token from the authorization service. The access control system may be further adapted to store the validation token in the cache.

摘要： This disclosure describes techniques for operating an inductive coupling reader. The techniques include operations comprising: detecting a change in a resonance frequency of the inductive coupling reader; comparing the change in the resonance frequency to a threshold; determining that the change in the resonance frequency falls outside the threshold; and activating a compensation circuit to offset the change in the resonance frequency of the inductive coupling reader in response to determining that the change in the resonance frequency falls outside the threshold.

摘要： Systems and methods for access control systems includes first and second access facilities, and first and second readers. The first reader is configured to control access through the first access facility. receive a credential using a first communication protocol from a device that stores the credential, and establish a secret with the device using the credential. The second reader is configured to control access through the second access facility. The first reader is configured to provide the secret to the second reader, and the second device is further configured to perform ranging using the secret and a second communication protocol different than the first communication protocol to identify intent information. Access through one of the first facility or the second facility is coordinated using the intent information.

摘要： The present disclosure relates to a reader, such as a reader for a physical access control system. The reader can include first and second antennas, each designed or configured for receiving ultra-wide band (UWB) signals. The reader can also include a mounting plane configured for mounting the reader to a surface. An axis aligning the first and second antennas can be arranged substantially perpendicular relative the mounting plane. A material can be provided between the first and second antennas. The material can have a thickness that defines a distance between the first and second antennas of less than a half wavelength of the UWB signal through air (λA/2), the material configured to slow down electromagnetic waves passing therethrough such that the thickness of the material provides an effective separation distance of the first and second antennas of at least a half wavelength of the UWB signal through air (λA/2).

摘要： A device connectable to a reader of an access control system includes an antenna, an ultra-wide band (UWB) front end circuit, a controller, and a communication link. The (UWB) front end circuit is connected to the antenna to facilitate UWB communication with a credential device. The controller is connected to the UWB front end and configured to perform ranging for the credential device using the UWB communication. The communication link is configured to interface with the reader.
