What is the best way for Chinese tourists to shop abroad with non-dollar currency?

To use non-US dollar currency for overseas shopping, it's recommended to use credit cards issued by UnionPay (also known as ChinaUnion). This method allows you to make purchases using UnionPay POS machines in various countries across Asia and Europe. UnionPay POS machines are more prevalent in these regions, making them suitable for non-US dollar transactions.

In terms of security concerns, it's advisable to carry at least two credit cards with you, especially a debit card that has sufficient funds. This ensures that even if your credit card is lost or stolen, there is still an option to pay with cash.

A double-currency card, which includes both VISA and MasterCard, can simplify your travel experience by allowing you to use either currency in the foreign country without needing to switch between them. This makes it easier to manage your finances while on vacation.
