What is the function of the "Keypad" on Verifone terminals?

The keypad on Verifone terminals serves an essential role in enabling users to input data necessary for completing a transaction. By allowing data entry, such as Personal Identification Numbers (PINs) and payment amounts, the keypad provides a means for customers to securely authorize transactions. This function is crucial for ensuring the accuracy and security of the payment process, as users can manually enter PINs to confirm their identity and specify the amount they wish to pay.

While transaction information is displayed on the screen and payment processing is handled by the terminal's internal systems, the keypad is specifically designed for user interaction through data input. The ability to connect to the internet is not a function of the keypad itself but rather the terminal's networking capabilities. Therefore, the keypad remains a vital interface for user input within the overall operation of Verifone terminals.
