At present, credit cards can generally be used directly abroad, but some banks will cancel the overseas quota in order to prevent credit cards from being stolen. If you want to activate them, you can bring your ID card and credit card to the counter of CITIC Bank to activate them.

Credit cards include single currency and double currency (or full currency) credit cards. UnionPay credit cards are generally used in China, and Visa and Master credit cards are mostly used abroad.

UnionPay credit card generally refers to a credit card with a single UnionPay logo, that is, the card issuer on the credit card only has a UnionPay logo, and the card numbers of UnionPay credit cards all start with 62, which means that a single UnionPay credit card can only take the UnionPay system, and whether the UnionPay credit card can be used overseas depends on the laying of overseas UnionPay POS machines and ATMs.

According to the survey, many countries around the world have laid the system of UnionPay. Although it seems that UnionPay's system has spread all over the world, except Hong Kong, Macao and Taiwan, the system laying density in other countries is much lower than that of Visa and Master. Many countries are only stationed in some areas of their capitals. In order to avoid losing the UnionPay system when swiping cards or withdrawing money abroad, it is suggested that cardholders take a dual-currency credit card of UnionPay +visa or UnionPay+MasterCard when traveling abroad.
