Biometric Access Control is a security device for letting selective people in your house, office, or any other type of building. There are ways to let people in your house or office by opening the doors for them, who you know, and wanting to let them in.
In the early days when there were no systems, almost everything was interpreted on analogy. The days were tough because almost any willing burglar was able to intrude on the property and take whatever asset he desires. This was because no entry and exit devices were present on the doors or on the whole house.
