Steel Keypads for Self-service Industry

Steel keypads are typically used in self-service machines, including bank ATM machines, elevators, vending machines, access control machine, ticket dispensers, and time clocks. These keypads are manufactured using stainless 304 steel to ensure durability and longevity, even in high-traffic applications.


The steel keypad provides an added level of security and tamper resistance, making it a popular choice for applications where security is a concern. These keypads are also easy to clean and maintain, which is essential for machines that are used frequently.

In addition to their durability and security features, steel keypads are also customizable, allowing you to choose the size, shape, and layout of the keys based on your specific needs. They can also be configured to work with different types of technology, including RFID, Bluetooth, and Wi-Fi.
