Foreign exchange cards refer to credit cards and debit cards issued by overseas banks or overseas credit card companies that can be used all over the world.

Foreign currency cards only have foreign currency single currency accounts, and the card number is determined according to different card issuers, which can be used in domestic and foreign card issuers' networks. Dual-label cards, as well as cards jointly issued by UnionPay and other card issuers, including RMB and foreign currency, can be used in domestic and foreign zd UnionPay networks or another card issuer.
