Organize Your Wallet
Wallet is a storehouse for virtual passes like coupons, reward cards, and tickets. It also manages your Apple Pay cards and settings.
Manage Wallet Passes
There are two ways to add passes:
When you encounter a Wallet pass QR code in the real world, open Camera, center the barcode in the viewfinder to scan it. Open the resulting notification to add that pass to Wallet.
Tap the Add to Wallet button on a webpage, in an email message, or inside an app. Some apps may add passes automatically.
Some passes are location- or time-based. These display a Lock screen notification at the appointed time or place. Other passes must be pulled up manually by opening Wallet and tapping the pass in the stack. Swipe down on the pass to return it to the stack.
To delete or edit a pass, open it, and tap the info 
icon in the lower-right corner. Tap Remove Pass to remove it, or toggle Suggest on Lock Screen.
Try Apple Pay
Apple Pay lets you use your Apple device in place of your credit or debit card. You can use Apple Pay in stores and apps, as well as on websites that support it. You can also use Apple Pay in Messages to send money to others.
To set up Apple Pay on an iPhone for making mobile payments on-the-go, you need an iPhone 6 or later (including the SE), or an iPhone 5S or later paired with an Apple Watch.
For in-app purchases and in-Safari (on the Mac) purchases, you can also use any of these iPads: at least an iPad Air 2, iPad mini 3, or iPad Pro.
Here’s how to set up Apple Pay in iOS:
Find out whether your credit or debit card is compatible with Apple Pay by checking with the card’s bank or looking for it in this Apple support article.
Go to Settings > Wallet & Apple Pay.
Tap Add Credit or Debit Card.
Follow the prompts to add your card(s) to Apple Pay.
If the details are accepted and your credit card issuer supports Apple Pay, the card is added to Wallet—possibly after an additional verification step by your financial institution; if not, an error dialog appears.
Use Apple Pay in a Store
Apple Pay works at any Apple Pay partner location (Figure 71). It may also work at other outlets that use a wireless reader—my local lumber yard accepts Apple Pay!
Here’s how to make a purchase:
Place your phone near the Apple Pay terminal.
While on the Lock screen, double-press the Home button to bring up Apple Pay. On the iPhone X, XS, XS Max, or XR, double-press the Sleep/wake button.
If you’ve set up multiple cards with Apple Pay, tap the one you want to use.
Enter your passcode, touch the Home button to activate Touch ID, or let Face ID scan your face.
Use Apple Pay in an iOS App
Several apps allow you to pay with Apple Pay, as follows:
In the app, tap the Apple Pay button.
At the next screen, review the information and edit as needed.
When you’re ready to pay, enter your passcode, touch the Home button to activate Touch ID, or let Face ID scan your face.
Use Apple Pay in Safari
If you’ve set up Apple Pay on your iPhone or iPad, you can use it to pay online when you’re shopping in Safari on the device.
If you see a “Pay with ” (or similar) option while checking out in a web-based cart, tap it. A payment dialog appears. Confirm your information and then press the iPhone’s Home button for a Touch ID fingertip scan. Or, on a Face ID device, double-press the side button and let it scan your face.
You can also use Apple Pay to pay online with your iOS device (or Apple Watch) when you’re shopping in Safari on a Mac running 10.12 Sierra or later. The Mac must be Continuity-savvy, meaning a 2012 or newer model, other than the Mac Pro, which must be a Late 2013 or newer model.
To set this up:
On your iPhone, go to Settings > Wallet & Apple Pay and enable Allow Payments on Mac.
On the Mac, open Safari, choose Safari > Preferences > Privacy, and make sure the checkbox “Allow websites to check if Apple Pay is set up” is selected.
