It's not yet clear exactly what the uses are for a TouchID sensor on the MacBook Pro laptop. If the iPhone's TouchID sensor is anything to go by, a TouchID sensor on the MacBook Pro would let you unlock your laptop without typing a password, pay for apps, and even use Apple Pay to pay for online shopping.
9to5Mac's sources also reinforced previous rumors that the next MacBook Pro will feature a row of customizable OLED touch-screen buttons that will take the place of the "F" keys that are usually above the row of number keys on a regular keyboard.
With customizable "F" function keys, which often go unused, you could potentially assign shortcuts to different apps, features, and functions. For example, you could change the location of the volume button "F" keys that are found on the right of Apple's keyboard to the "F" keys on the left.
Currently, you can't switch the location of function keys, like volume controls, as they are permanently set on Apple keyboards.

9to5Mac's reports of TouchID and an OLED touch-screen on the new MacBook Pro laptops are reinforcements of an earlier report posted in May by KGI Securities analyst Ming Chi-Kuo, who has accurately predicted features on new Apple products in the past.
Despite the accurate predictions and reliable sources, nothing about Apple's new MacBook Pro laptops is set in stone until Apple itself reveals the new models during its Fall event in September.
