Paying for a Purchase Using Your Watch
Before you can use your watch to pay for purchases, you must set up at least one payment card.
You can use your watch to pay for purchases in a participating store.
TIP:
After you successfully enter your passcode, you can make payments without a passcode for 24 hours while you continue to wear your watch. If you remove the watch from your wrist or disable heart rate monitoring, you must enter the passcode again before making a payment.
