Apple Pay: How to set up and use it on your iPhone, Apple Watch and Mac

It's faster, more secure and more convenient than using your actual credit cards.

Despite the number of people who own an iPhone or an Apple Watch, there are still plenty of them who don't use Apple Pay. And that's a shame because it's uniquely positioned to bridge transactions on your iPhone with those in actual stores. 

Apple Pay is basically a digital wallet on your iPhone, iPad, Apple Watch or Mac that lets you buy things in restaurants, in retail stores, in apps and on the web. You can even use it to send and receive money to friends and family with Messages.

Even though there's an image of your credit card in Apple's digital Wallet, your card number is never stored on your phone or on Apple's servers. Instead, Apple Pay uses a specific device number and a unique transaction code to process payments and protect your information. This allows Apple Pay to be faster and more secure than using a physical credit card at a register.
