A method of monitoring access requests to one or more access controls of an access control system is provided. The method comprising: receiving a first access request from a key card to a first access control, the key card being encoded with a credential and an access code; determining that the credential is not authorized to access the first access control; checking a first value of the access code; and rewriting the first value of the access code to a second value of the access code if the first value of the access code does not equal a desired value of failed access request attempts.

The invention provides a digital lock (100) including at least two magnets. One magnet is a semi hard magnet (310) and the other magnet is a hard magnet (320). The hard magnet (320) is configured to open or close the digital lock (100). The semi hard magnet (310) and the hard magnet (320) are placed adjacent to each other. A change in magnetization polarization of the semi hard magnet (310) is configured to push or pull the hard magnet (320) to open or close the digital lock (100).

Barricade devices and methods of barricading a door are disclosed. Such devices and methods may be used to barricade a door, and thereby prevent an intruder from entering a sheltering space, such as a classroom, storeroom, or hallway. The barricade-device may have a pivotable stop-device that is pivotable from a location adjacent to a door. The pivot-location may be at an elevation that is lower than a door handle. The stop-device may be pivotable from a reserve-position to a stop-position. In the reserve-position, the stop-device does not barricade the door. In the barricade-position, the stop-device barricades the door. Operation of the barricade-device may require the application of an activation operation to an activator. A wide range of people having differing physical and mental capabilities may use the barricade-device properly and quickly.

A door system and method for a door system is disclosed. A door body of the door system carries access control system components such as access readers, request to exit devices, and possibly magnetic lock systems, in examples. In embodiments, other devices carried by the door body include detection devices that detect physical phenomena, an interactive display, a door controller, and a power management system. The power management system provides a source of power to the other devices carried by the door body.

A monitoring system for allowing a guardian to monitor a keeper, the monitoring system a guardian unit to be worn by the guardian, the guardian unit has a power source; and a transceiver; a key incorporated into the guardian unit; a band to be worn by the keeper, the band having a GPS unit; a lock to release the band from the keeper; a power source; and a control system having a transceiver to wirelessly communicate with the transceiver of the guardian unit; the lock is to unlock through communication with the key of the guardian unit; a network, having a computing device; and a platform accessible from the computing device; the platform is to allow the guardian to monitor activity associated with the keeper via data received by the control system of the band.

An interlock system comprising: a first lock including a first lock memory configured to store one or more virtual keys; and a first key including a first key memory configured to store one or more virtual keys, wherein the first lock is configured to be actuated between a first condition and a second condition, when a first virtual key stored in the first key memory is transferred to the first lock memory, by engagement of the first key and first lock, and movement of the first key with respect to the first lock.

A magnetic strip card includes a partial encrypted card payload encrypted with a long shared key to provide a final encrypted payload. A method for encoding the magnetic strip card includes encrypting a card payload with a code key of a access controls with a short key of the access control to generate a partial encrypted payload and encrypting the partial encrypted payload with a long shared key to provide a final encrypted payload.

Disclosed systems and methods relate to a smart access control reader for an access control system. According to embodiments, a method can include installing the smart access control reader to the access control system by connecting the smart access control reader to the access control system via wiring of the access control system. The method can also include receiving, by the smart access control reader, one or more first credentials for authenticating one or more users by the access control system. The method can further include determining, by the smart access control reader, that the one or more first credentials are authorized. Moreover, the method can include transmitting, by the smart access control reader, a second credential to an access control panel of the access control system, in response to a request by a first user to access an area monitored by the access control system.

An access control device including an electromagnetic lock module for selectively locking and unlocking a door in a door frame is provided. The access control device provides a lower profiled electromagnetic lock module to improve the aesthetics and functionality of the module, supports and integrates modern accessories such as CCTV, CCD cameras, passive motion detection with automatic background correction, digital notification display, automatic source voltage selection, door and lock status indicators, and ease of installation. The present invention further provides components and circuitry to enable connection of the electromagnetic control module to 12 or 24 volts DC or to an unfiltered rectified AC power supply.

One or more embodiments describe a magnetic actuator including at least two magnets. One magnet is a semi hard magnet and the other magnet is a hard magnet. The hard magnet is configured to open or close the magnetic actuator. The semi hard magnet and the hard magnet are placed adjacent to each other. A change in magnetization polarization of the semi hard magnet is configured to push or pull the hard magnet) to open or close a digital lock realised with the magnetic actuator. The magnetic actuator can also be used to realise a valve.
