Tips

The QR code generated by ALIPAYBOTH can be scanned using either the "支付宝" app or the "支付寶香港" app.
For WeChat, if the merchant is integrated with a wallet institution, the value can be either WECHATHK or WECHATCN to place an order. The wallet type returned in the final transaction will depend on the wallet used by the customer for payment.
