Used in ATMs and POS terminals, ________ allow for the input of data with the use of a stylus or finger.

• A. Keyboards
• B. Touchscreens
• C. Mice
• D. Scanners

Answer: (B)

Touch input on a display is what’s being tested here. Touchscreens let you enter data by tapping the screen with a finger or a stylus, which is exactly how ATMs and many POS terminals collect input—digits for PINs or amounts, and selections from on-screen menus. The other options rely on separate hardware: keyboards use physical keys, a mouse moves a cursor to click, and scanners read data from printed or physical media. So the best fit for input with a stylus or finger is a touchscreen.
