Use the Apple Watch to Pay
Just like your iPhone, the Apple Watch also supports Apple Pay. This handy feature will let you basically “transfer” your credit card or other payment card details to your Apple Watch so you can pay just by raising your wrist.
All you need to do is press the Apple Watch’s side button, and you’ll see your payment cards pop up on the screen. Apple Pay is available on pretty much any Apple Watch, but you need to have it paired with at least an iPhone 5 or newer model.
