Access Control stands for restricting the non-authorized person to grant access to a certain area in both hardware and software ways.

 

For instance, a resident living in the compartment can grant entry into the main entrance of the compartment, car park, etc. Access Control can be divided into two different recognition methods: digital or bio-metrical.

 

Most common example using digital recognition is using card readers or entering a password to grant entry. For biomedical, it can be determined through bio metric characteristics of human bodies, such as fingerprints and facial recognition.
