Brand detected automatically from shopper barcode
When you make QR code payments by scanning the barcode on the shopper's device, you no longer need to specify the brand of digital eWallet (AliPay or WeChatPay) in the payment request. Instead, you can leave the
AllowedPaymentBrand field empty and we will determine the brand on the terminal.
To comply with the latest Visa scheme rules, the Application Identifier (AID) is now printed on the terminal receipt.
