Cross-border e-commerce recommends using a dual-currency card.
Take Amazon as an example. Many credit card organizations are supported, including Visa, Master, AmericaExpress, JCB, and even UnionPay in China. Therefore, even if you are only a single-currency credit card of China UnionPay (beginning with 62), you can still do Haitao in Amazon. However, if the scope of Haitao is extended to other websites, it is best to do dual-currency credit cards, such as Visa and Master.
