Readers
Credentials
-
A reader is an electronic component of a physical access control system.
-
The device is used to “read” the access credentials in order to verify a user’s access to a secured area.

There are many types of readers for access control systems.

Access Control
At TESS we define access control as a way of limiting access to a system or to physical or virtual resources. There are four main elements that make up an access control system, which are credentials, readers, locking devices and controllers/panels.
-
Credentials are defined as a physical or tangible object, a piece of knowledge or a facet of a person’s physical being, that enables an individual access into a physical facility or a PC-based information system.
-
Some examples of credentials include card, token, PIN code, fingerprint, face, palm and more.
-
Credentials must be presented by the user before they can be granted access to a secured area.
Controllers/Panels
Locking Devices
-
Controllers and panels are used to process access control activities for all doors connected to it.
-
They are normally installed near each door where access control is to be provided.
-
It is there where all connection to the door devices terminates.
-
Some of these panels are integrated with readers.
