Compared with ordinary credit cards, full-currency cards have the following advantages:

1. Full-currency international credit cards can automatically purchase foreign exchange and repay in RMB;

2. No additional credit card annual fees are waived within the validity period;

3. For any foreign currency consumption around the world, there is no currency exchange fee.

Whether it is good or not depends on the specific situation of the customer. For example, if you often use it overseas, a full-currency card is more convenient than a dual-currency card or a UnionPay single-currency card. If you use it frequently within the country, it is of course better to apply for a UnionPay card.
