What is the purpose of a “keypad” in EAC systems?

The purpose of a keypad in Electronic Access Control (EAC) systems is primarily to allow users to enter a code for access. This functionality is essential for controlling entry to secured areas, as it enables authorized personnel to gain access by inputting a specific numeric or alphanumeric code. The keypad serves as an interface through which the user communicates with the access control system, facilitating a direct method of authentication.

By utilizing keypads, organizations can effectively manage and monitor who has access to certain locations, while also maintaining a level of security that can be adjusted to changing circumstances—for example, by altering codes or restricting access as needed. This capability is crucial in environments where traditional keys may pose security risks or where there is a need for more flexible access control.

In this context, other options do not align with the primary function of a keypad. For example, disabling all digital access would contradict the idea of controlled entry. Similarly, suggesting that it functions only in conjunction with magnetic locks limits its versatility, as keypads can work with various types of locking mechanisms. Lastly, providing security without a power source is not a typical function of a keypad, as most electronic keypads require power to operate effectively.
