It is remarkable that a compact device like the Apple Watch can house a myriad of sensors, and by extension, deliver those useful features we have heard about continuously. However, for all that the Apple Watch houses, it still lacks Touch ID, and for the foreseeable future, things might not change.

On the Power On newsletter by Mark Gurman, he mentions that the Apple Watch will not arrive with a fingerprint reader, though the reporter continues to believe that there are several ways that this security addition could be beneficial. He states that approving payments via Apple Pay using Touch ID could be extremely useful. Previously, Apple’s executives have voiced their intentions to replace physical wallets with the company’s smartwatch.
