Use Apple Pay when the Wallet app is not your default contactless app
Make Apple Pay transactions when the Wallet app is not set as your default contactless app.
Making Apple Pay transactions
If you select another contactless app as your default app, it will impact how you use Apple Pay & Wallet. When you double-click the side button or hold your iPhone near a contactless reader in-store, your selected app will launch automatically after you have unlocked your iPhone. The cards you've saved in your Apple Wallet to make Apple Pay transactions will no longer be presented.
To make contactless transactions with Apple Pay
On your iPhone, open the Wallet app.
Select your card.
Double-click the side button to authenticate with Face ID or enter your passcode before making a payment.
If you want Apple Pay and the Wallet app to launch automatically when you double-click the side button or hold your iPhone near a contactless reader, you'll need to select Apple Wallet as your default contactless app in Settings.
Using Express Mode
Express Mode will continue to work even if Apple Wallet is not your default app. With Express Mode, you can use some cards, keys, and passes in Apple Wallet without waking or unlocking your device, or authenticating with Face ID, Touch ID, or your passcode.
