What is Keypad?

A keypad is an input device made up of a set of buttons or keys that allow users to enter numbers, letters, or commands into a system. It is commonly used in security panels, access control systems, ATMs, and electronic devices. Keypads provide a simple and reliable way to interact with machines, authenticate users, or control operations.

Keypads are available in different designs, like numeric pads, alphanumeric layouts, and modern touchscreen designs. They help to perform faster data entry while improving user convenience in everyday operations. By requiring PINs or passwords, keypads also strengthen security and help control access to sensitive systems.
