# Terminal Input Options

The PAX A35 terminal offers an on-screen keypad as well as a physical keypad to enter transaction amounts. Your terminal operators and customers enter information and respond to prompts using either the terminal’s touch screen or physical keypad.

To enter an amount or a PIN, you can use either the on-screen or physical keypad.

There are three (3) colored function keys on the physical keypad that you can use to confirm, correct, or cancel an operation:

* To confirm an entry, touch **OK** on the screen or press the green **O** key
* To correct an entry, touch **BACK** on the screen or press the yellow **<** key&#x20;
* To cancel a function, touch **CLEAR** on the screen or press the red **X** key
