How Chase Pay POS Works
1
The customer uses your app and chooses Chase Pay.
2
Your app uses the Chase Pay SDK to authenticate the customer credentials for the Chase Pay wallet with the Chase Pay host, obtains the session ID, and retrieves a list of the credit cards that are in the customer's Chase Pay wallet.
3
Your app displays the list of credit cards, and the customer selects a card.
4
Your app sends the session ID, account index, and order details to your order management system.
5
Your order management system uses the session ID and account index to retrieve the payment details from the Chase Pay host.
6
Your order management system matches the customer's shopping cart to the customer and the payment details.
7
To process the payment, your order management system sends a request through CyberSource to Chase Paymentech Solutions. In addition to the basic fields required for retail chip card processing, you must also include the following fields in your request:
●
paymentNetworkToken_requestorID—Set the value for this field to the value assigned by the token service provider.
●
paymentNetworkToken_transactionType—Set the value for this field to 1, which indicates that tokenized track data is included in the request.
●
pos_entryMode—Set the value for this field to QRCode.
●
pos_terminalCapability—Set the value for this field to 4.
●
payment_solution—Set the value for this field to 007, which indicates that this is a Chase Pay transaction.
The preceding fields are described in API Fields.

In the reply message that you receive from CyberSource, the ccAuthReply_ paymentNetworkTransactionID value is the Visa transaction ID. This value is returned only for approved transactions.
