Abstract: 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.

Abstract: 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.

In an example, an access control system may regulate access to an asset. The access control system is adapted to receive a credential from a key device associated with a user using a first wireless connection. The access control system may be further adapted to verify the credential with a preliminary authentication for the asset. The access control system may be further adapted to establish a second wireless connection with the key device in response to verifying the credential with the preliminary authentication. The access control system may be adapted to determine an intent of the user to access the asset. The access control system may identify the credential includes a pattern in the preliminary authentication. The access control system may be further adapted to provide a command to grant access to the asset.

Abstract: A reader system for an access control system includes first and second antennas and first and second controllers. The first controller is configured to communicate with a credential device using a first communication protocol via the first antenna to exchange a credential with the credential device. The second controller is configured to communicate with the credential device using a second communication protocol via the second antenna to perform ranging for the credential device and is configured to communicate with the first controller via a communication link.

Abstract: 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.

Abstract: 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 establish a first connection with a key-device. The access control system may be further adapted to receive a credential for a user over the first connection. The access control system may be further adapted to establish a second connection with the key-device. The access control system may be further adapted to determine an intent of the user to access the asset. The access control system may use location data derived from the second connection to determine the intent of the user. The access control system may be further adapted to provide the credential to an access controller, based on identifying an intent of the user to access the asset.

Abstract: A compensated antenna array (108) and an RFID system including the compensated antenna array are disclosed. The antenna array includes a first antenna (208) and a second antenna (204) where the first antenna is positioned within the second antenna and overlaps itself at least one point (216) such that at least some induced current in the first antenna is offset by at least some induced current in the second antenna and such that at least some induced current in the second antenna is enhanced at the at least one point of overlap.

Abstract: A reader is proposed that includes a reader core having a web server provided thereon. The web server is made accessible to users via an advertised IP address. One set of scripts made available via the web server provide a user with the ability to optimize a tuning network for the reader.
