How does Mastercard Merchant QR Code replace PoS (Point of Sale)?

"The diagram below shows how Mastercard MPQR (Merchant Presented QR) works. There is no POS terminal or physical card involved.

🔹 Step 1: The merchant presents its QR code at checkout.

There are two types of QR codes:

• Dynamic: the code is generated for each transaction and includes the payment amount

• Static: the code is used for all transactions

🔹 Step 2: The customer scans the QR code using a mobile app and confirms the payment.

🔹 Step 3: The payment app sends transaction data to the transaction originator to initiate MPQR payment.

🔹 Step 4: The transaction originator debits the customer's account in the customer's bank.

🔹 Steps 5 and 6: The transaction originator sends a payment request to the Mastercard network. Mastercard routes the payment request to the merchant's bank.

🔹 Steps 7 and 8: The merchant's bank approves or declines the request. If it is approved, the merchant's bank credits the merchant's account.

🔹 Steps 9 - 11: The payment response is sent back all the way to the mobile app."
