In China, most credit cards with UnionPay logo are used, and credit card swipers only support UnionPay credit cards. Other cards, such as Visa and MasterCard, are rarely used. In foreign countries, most countries support Visa and MasterCard credit cards, so these two cards can basically be used abroad. The "CREDITGOLD" logo can only indicate that its card is a gold card.
