QR code and barcode are ISO-compliant encoding and visualization of data. This standard covers the QR codes used in the merchant-presented mode (MPM) for payments in brick-and-mortar stores. In this mode, QR codes are presented by merchants on either acceptance materials or user interfaces for consumers (users) to scan with their mobile devices.

You can gain an overview of store code and order code that are available in the merchant-presented mode. You can also see the benefits of merchant-presented mode. You can then get started with the details.

Store code

Store codes are the QR codes printed by merchants on the acceptance materials for consumers to scan and initiate payments. It's cost-efficient for small and micro merchants, as well as self-employed businesses.

User experience

Figure 2.1 User experience of store code in merchant-presented mode

This diagram illustrates how payment is completed by the store code of the merchant-presented mode.

1. At the cashier, a consumer opens his/her e-wallet app to scan a store code to identify the merchant or store information.
2. The consumer enters the transaction amount.
3. The consumer confirms the payment.
4. Payment is now completed automatically.

Order code

Order codes are the QR codes displayed by merchants on their vending machines or other channels. The difference with a store code is that the transaction amount is generated automatically after consumers scan the order code. The automation process can reduce transaction failures, such as amount error, return, and dispute. It's suitable for retailers and self-checkout scenarios.

User experience

Figure 2.2 User experience of order code in merchant-presented mode

This diagram illustrates how payment is completed by the order code of the merchant-presented mode.

1. At the cashier, a consumer opens his/her e-wallet app to scan an order code to identify the order information.
2. The consumer confirms the payment with a fixed amount that is automatically generated. 
3. Payment is now completed automatically.
