Best Access Control and ID Card Printer in Dubai
In the fields of physical security and information security, access control (AC) is the selective restriction of access to a place or other resource. The act of accessing may mean consuming, entering, or using. Permission to access a resource is called authorization.
Locks and login credentials are two analogous mechanisms of access control.
There are three types (factors) of authenticating information
- something the user knows, e.g. a password, pass-phrase or PIN
- something the user has, such as smart card or a key
- something the user is, such as fingerprint, verified by biometric measurement
