Xiaobai Card innovatively adopts UnionPay multi-currency account, and one card can enjoy RMB account and four commonly used foreign currency accounts of US dollar, Euro, Macao pataca and Hong Kong dollar, which can be used in UnionPay networks at home and abroad. When it is used in the UnionPay network of countries or regions corresponding to four foreign currencies, it can be directly recorded in the corresponding currency without paying foreign exchange fees. It can be repaid directly in foreign currency or by purchasing foreign exchange in RMB. When it is used in countries or regions other than four foreign currencies, the UnionPay network is used and credited to the RMB account, and the foreign exchange handling fee is automatically exempted.
