ApplePay is a work of Art that enables online and in-store transactions, but how? 👇
In this specific payment scenario, ApplePay uses to send payment data to the contactless POS terminal with its Tap & Pay feature.

🔸Once authentificated, the Secure Element generates a , combination of Payment Token, Transaction Amount, Transaction Counter etc and a . The Secure Element passes the Payment Token (DAN), Dynamic Cryptogram and Dynamic CVV alongside other information to the POS Terminal via NFC.
🔸 The POS sends this request to the Bank (Merchant Bank, Nuvei, Stripe…) which in turn forwards it to the Payment Network i.e. Visa, Mastercard etc.
🔸The Payment Network (also called Card Network) identifies the specific Payment Token and passes it and the Dynamic Cryptogram to the Token Service Provider ( ) to obtain a Payment Card Number ( ).
🔸The Token Service Provider receives the Payment Token ( ) and the Dynamic Cryptogram. After verification, it returns a real PAN to the Payment Network.
🔸The Payment Network passes the PAN along with the transaction details and CVV to the Bank - Wells Fargo, Bank of America for authorization.
🔸The Issuer validates the request by deciphering the Dynamic CVV using its private key to check the credit balance against the transaction amount.
🔸If authorized, the Issuer Bank passes back the authorization response to the Payment Network, back to the Acquirer and finally the POS system of the Merchant ✅
This happens lightning fast ⚡️and with extreme convenience. Apple built its payment ecosystem with Apple Card, Apple Cash, ApplePay Later and various other services like In-app payments to achieve a seamless User Experience ( ) to both the Merchant and Consumer.
