The act of accessing may mean consuming, entering, or using. Permission to access a resource is called authorization .

  3. Door security - Wikipedia

    en.wikipedia.org/wiki/Door_security

    The term door security or door security gate may refer to any of a range of measures used to strengthen doors against door breaching, ram-raiding and lock picking, and prevent crimes such as burglary and home invasions. Door security is used in commercial and government buildings, as well as in residential settings.

  4. Mantrap (access control) - Wikipedia

    en.wikipedia.org/wiki/Mantrap_(access_control)

    A mantrap, security mantrap portal, airlock, sally port or access control vestibule is a physical security access control system comprising a small space with two sets of interlocking doors, such that the first set of doors must close before the second set opens.

  5. Electromagnetic lock - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_lock

    The principle behind an electromagnetic lock is the use of electromagnetism to lock a door when energized. The holding force should be collinear with the load, and the lock and armature plate should be face-to-face to achieve optimal operation. The magnetic lock relies upon some of the basic concepts of electromagnetism.

  6. Door - Wikipedia

    en.wikipedia.org/wiki/Door

    A door. A door is a hinged or otherwise movable barrier that allows ingress (entry) into and egress (exit) from an enclosure. The created opening in the wall is a doorway or portal. A door's essential and primary purpose is to provide security by controlling access to the doorway (portal).

  7. Remote keyless system - Wikipedia

    en.wikipedia.org/wiki/Remote_keyless_system

    A remote keyless system (RKS), also known as remote keyless entry (RKE) or remote central locking, is an electronic lock that controls access to a building or vehicle by using an electronic remote control (activated by a handheld device or automatically by proximity).

  8. Proximity card - Wikipedia

    en.wikipedia.org/wiki/Proximity_card

    Proximity card. A passive proximity card for door access. A proximity card or prox card [1] also known as a key card or keycard is a contactless smart card which can be read without inserting it into a reader device, as required by earlier magnetic stripe cards such as credit cards and contact type smart cards. [2]

  9. Physical security - Wikipedia

    en.wikipedia.org/wiki/Physical_security

    Mechanical access control systems include turnstiles, gates, doors, and locks. Key control of the locks becomes a problem with large user populations and any user turnover. Keys quickly become unmanageable, often forcing the adoption of electronic access control. Electronic access control systems

  10. Electronic lock - Wikipedia

    en.wikipedia.org/wiki/Electronic_lock

    Electric locks use magnets, solenoids, or motors to actuate the lock by either supplying or removing power. Operating the lock can be as simple as using a switch, for example an apartment intercom door release, or as complex as a biometric based access control system.

  11. Interlock (engineering) - Wikipedia

    en.wikipedia.org/wiki/Interlock_(engineering)

    Different kinds of security interlocks can range from doors to electronic systems such as face or fingerprint recognitions. In high-security buildings, access control systems are sometimes set up so that ability to open one door requires another one to be closed first. Such setups are called a mantrap.
