When using a UnionPay credit card to make purchases in Hong Kong, merchants will settle directly through the UnionPay channel. When the card is swiped, the Hong Kong dollar price will be directly converted into RMB according to the real-time quoted price, and there is no currency conversion fee. You can pay directly in RMB when repaying your credit card. ——This is the most commonly chosen and most cost-effective settlement method.

2. UnionPay dual-currency credit card, taking UnionPay/VISA card as an example. When merchants settle, they usually see the logos of two settlement channels on the card, and they will actively ask you which channel to use for settlement. It is recommended to choose the UnionPay channel. The situation is the same as 1.

3. If you hold a UnionPay/VISA card, or a single VISA card, and the merchant has not joined the UnionPay settlement channel (just pay attention to whether the merchant has a UnionPay logo), this is the merchant's direct payment. Use VISA (Master, JCB, American Express, etc.) channels for settlement. Accounting will be done directly in Hong Kong dollars, but because domestic dual-currency credit cards are usually RMB/USD credit cards, the card will automatically convert Hong Kong dollars into US dollars during settlement (there are currency conversion procedures ranging from 1[] to 2[] fee), which will be shown in the US dollar bill when the credit card bill is issued at the end of the month. On the repayment date, you can purchase US dollars to repay the bill yourself, or the bank will automatically purchase US dollars to repay the bill.

4. You hold a multi-currency credit card, such as the VISA multi-currency credit card that banks now recommend. This card only has the VISA mark and can only be settled through the VISA channel. But the advantage is that the bill can be automatically converted into RMB according to the real-time quoted price during settlement, and the intermediate currency conversion fee is waived. When repaying a credit card, you only need to repay according to the RMB amount shown on the bill. ——If you often go overseas to spend money, it is recommended to get a multi-currency credit card like this.
