Why keyboards are used in ATM?

Keyboards are used in ATMs to allow users to input their personal identification numbers (PINs), select transaction types, and enter amounts for withdrawals or deposits. The tactile feedback and layout of keys make it easier for users to navigate the system securely and efficiently. Additionally, keyboards can accommodate accessibility needs, ensuring a wider range of users can interact with the machine. Overall, they enhance the user experience by providing a straightforward method for transaction input.
