If you add a card to your supported smartwatch, you won't need your phone to pay.
To make a payment in-store:
- On your watch, open the Google Pay app Google Pay.
- Hold your watch over the contactless payment terminal until you hear a sound or feel vibration from your watch.
- If asked, choose "Credit" regardless of your type of card.
- For debit card transactions, you may have to enter a PIN. Use the PIN you set up with your bank
