It can be used in the United States, but this single-currency card can only be used on machines with UnionPay logo abroad.

If you have a credit card with VISA, MASTERCARD, JCB or American Express logo, you can use it overseas (including Hong Kong, Macao and Taiwan) (including online payment). Credit cards through international routes will be settled in US dollars in consumption abroad. If the consumption amount is not USD, there will be an exchange fee between the two currencies, that is, 65438+ 0.5% of the transaction amount. If the consumption amount is USD, no settlement fee will be charged.

A dual-currency card can have two rows of choices. For example, VISA, MasterCard, JCB and American Express are all international credit card organizations, among which VISA has the widest coverage, and the special merchants are mainly concentrated in North America, Asia Pacific and other regions; MasterCard's special merchants are mainly concentrated in Europe, Southeast Asia and other regions; JCB- Japan Credit Card Co., Ltd., the special merchants are mainly concentrated in Japan;

American Express has issued American Express cards in 49 currencies in 68 countries and regions, and has more than 60 million high-quality cardholders worldwide. After the successful application, the basic functions of the card are the same, but the credit card quota is different, the special merchants are different, and the promotion activities abroad are different.

I hope my answer is helpful to you.
