How to Set Up & Use Apple Pay on Apple Watch
Apple Watch supports Apple Pay, which basically lets you use your watch as a super-fast payment mechanism in a variety of stores, ranging from Whole Foods to Starbucks, with many more coming onboard. Just like Apple Pay on the iPhone, the payments are processed and handled by a credit card or debit card, and thus you’ll need to set up the Apple Watch to use Apple Pay before you’ll be able to make quick payments with the device.
Once you have Apple Pay setup on the Apple Watch, you’ll be able to make payments and purchases remarkably quickly with basically just a quick swipe of your wrist.
