How will Apple pay work with Apple Watch?

How exactly will you be able to use your Apple Watch to make purchase through Apple Pay? In the iPhone 5S and above, you will be able to make purchases with Apple Pay securely using the touch ID feature.
The Apple watch, however, does not have a touch ID feature. It will instead use a manually entered pin code to authorize Apple Pay payments, a pin code that is only active whilst it’s on your wrist.
Using sensors on the back of the watch, it can tell immediately and automatically when you’ve taken the watch off your wrist. Once you take it off, you can’t use it to make purchases via Apple Pay until it is back on your wrist, and you’ve entered the pin.
So there you go. Easy peasy bacon-cheesy. We hope. We’ll find out early next year when the Apple watch is officially released!
Dammit. Now we want bacon.
