① Among the dual-currency cards issued by domestic banks, one of the currencies must be RMB and the other is a foreign currency. Usually, the vast majority of foreign currencies are US dollars, and a few are also Euros or Japanese yen. , or Australian dollar. For those with RMB, all bank cards issued now, whether they are debit cards or credit cards, must have the UnionPay logo. The so-called UnionPay dual-currency card actually means that the credit card has the UnionPay logo.
② Domestically issued dual-currency cards generally do not use foreign currency to pay domestic merchants. Foreign currencies on credit cards are generally used overseas, such as Hong Kong, Macau, and foreign countries, or to pay foreign merchants, such as SAT mechanism. For foreign currency settlement, if the merchant wants to get the money you paid (mostly US dollars), it must go through an international bank card settlement organization to debit the bank to which your credit card belongs. For example, VISA and MasterCard are such organizations, and domestic credit card issuing banks In order to allow customers to settle foreign exchange with foreign merchants, the main thing is to join VISA and MasterCard, the two major international bank card organizations, so the credit card has the VISA or MasterCard logo. However, it is rarely called VISA dual currency card in China.
③ UnionPay is also a bank card settlement organization, similar in nature to VISA and MasterCard organizations, and they are on an equal footing. Originally, banks in mainland China mainly participated, but now overseas banks also participate. However, only banks in my country's Hong Kong and Macau actively use the UnionPay logo on debit cards and credit cards issued by overseas banks. Other participating overseas banks are just to facilitate mainland tourists to choose the UnionPay channel when using local debit cards and credit cards to directly convert foreign currencies into RMB for settlement.
④ As long as the dual-currency card you apply for has the VISA or MasterCard logo on it, you can pay the SAT registration fee.
⑤ Bank cards without the VISA logo cannot be used as VISA cards.
