I wonder if WeChat payment can be used in Japan and South Korea? Do you write it for each hotel? Can I only use UnionPay? How are they paid?

Alipay can be used in South Korea.

Most stores in South Korea support Alipay wallet "pay in person" barcode payment, including Lotte Department Store, Myeongdong Main Store, Lotte Duty Free Shop, World Tower Store, and most stores in Myeongdong business district, such as Ba Nilan, Misshang, Skin Care, Royal Skin Care, Natural Beauty and Country, Olive Ocean, Lloyd and so on.

How to use:

When checking out, open the "pay in person" barcode payment function of the Alipay wallet on your mobile phone, show your mobile phone to the cashier, and the cashier only needs to scan it with a QR code scanner The payment can be completed using the barcode on the mobile phone. The settlement amount will be converted into RMB based on the foreign exchange rate of the day and deducted directly from the Alipay account.
