Pay With Your Wrist
Another cool feature many Apple devices have is Apple Wallet. This lets you add your credit or debit card to your iPhone, so you can pay just by putting your iPhone close to the payment terminal.
However, there’s an even easier way to do it. If you have an Apple Watch, you don’t even need to have your iPhone with you; you can simply double-press the Side button, and you’ll be able to pay with your Apple Watch just as quickly.
The best part is that Apple is always improving this feature. For instance, watchOS 11 is bringing a feature called Tap to Cash. With this feature, you can make or receive deposits from people just by putting your Apple Watch near their own Apple Watch or iPhone.
