Diners gather for meals at a Korean restaurant in Shenzhen, Guangdong province. CHINA DAILY

　　An American arriving at Shenzhen Bao"an International Airport in Guangdong province can buy a coffee with PayPal. A South Korean shopping for electronics in Huaqiangbei, a sprawling electronics hub, can pay with Hana Pay. A Vietnamese visitor dining in Shekou can settle the bill with ZaloPay.

　　In each case, there is no need to download a new Chinese payment app. Visitors can open the digital wallet they already use at home, scan a WeChat Pay QR code and pay in much the same way they would back home.
