1. overseas credit card consumption settlement is generally the settlement channel of VISA, but in addition to mainland China, there are still more than 9 countries and regions that can take the unionpay settlement channel (including south Korea). Just remind merchants to take the unionpay channel when swiping the card.

2-3. If you can take the settlement channel of UnionPay, it will definitely be more cost-effective than VISA, because the currency settlement fee of UnionPay is free, and the local currency will be directly settled into RMB through the settlement channel of UnionPay. VISA, on the other hand, settles the local currency into US dollars and then RMB, and the currency settlement fee is 1%-2% of the consumption amount.

4. remind the merchant to take the unionpay channel when swiping the card. if VISA has forced the merchant to take the VISA settlement channel, the unionpay channel cannot be taken. Take more cards for overseas travel:

If you have dual-currency cards of MasterCard and UnionPay, you can still remind merchants to take the UnionPay channel;

use unionpay's single-currency card (the most common card in China, but single-currency cards can't be cashed out abroad) when swiping a card. As long as it is a single-currency card, there will be no settlement fee.

VISA, an international card organization, recently sent a letter to member banks around the world, demanding that from August 1st, when accepting dual-currency credit cards with the VISA logo outside Chinese mainland, no matter whether they use credit cards or withdraw cash at ATM, they should not go through the clearing channel of China UnionPay, otherwise VISA will severely punish the acquiring bank.
