    1. Biometric authentication is used to verify the customer.

    2. The Apple Pay servers encrypt the DPAN from the secure element to generate a payment token.

    3. The payment token is sent to the Merchant or the Hosted Payment Portal. If using the Payment Gateway directly, the payment token must be decoded.

    4. The transaction information is sent to MerchantE.

    5. The Merchant receives the verification and completes the transaction.

    6. Apple Wallet is notified of the approved transaction.

    When a user purchases goods or services from your website, PassKit (mobile) or Apple Pay JS (Safari) determines they are using a qualified device. If they are using a qualified device, the Apple Pay button will appear as one of the payment options.

    Info

    Note: The Apple Pay button will only be displayed if using an approved Apple device or the Safari browser.

     If the customer selects Apple Pay as the payment method, they are immediately presented with the Payment Sheet. The Payment Sheet will present the customer with their stored payment options. This includes the card payment option and address.

    Info

    Note: If no payment options are available, the customer will be directed to set up an Apple Pay account with stored payment options.

    Once the customer has selected a payment option and authorizes the request using a linked device, a payment request is created. If authorization succeeds, a payment object is generated. The payment object contains all the customer data and the payment token.

    The payment token is then decrypted by the MerchantE Payment Gateway. The decrypted payment token contains:

    • Device specific authorization number (DPAN)

    • Payment amount

    • One-time-use cryptogram

    The contents of the decrypted payment token are then sent to the card issuer to complete the payment.
