The difference between foreign currency credit cards and ordinary local currency credit cards is that foreign currency credit cards can be settled again, for example, US dollar accounts, Canadian dollar accounts, Japanese yen accounts, etc. Generally, foreign currency credit cards are used for payment in consumption abroad, but ordinary domestic credit cards cannot be used in consumption abroad. Foreign currency credit card repayment is now simplified. It can be repaid like an ordinary credit card, and it can be repaid automatically by purchasing foreign exchange.
