Make sure Near Field Communication (NFC) is turned on for your device.
Open your digital wallet, choose your card, and hold your device near the contactless reader until the payment is complete.
If the merchant has trouble processing the wallet payment, try another contactless reader or ask if you can key in your card details instead.
Always know your balance before you pay by checking the card in your profile or using the retrieval email link to view full card details for online purchases.
