There are five major credit card brands in the world, two major organizations: VISA International and MasterCard International, as well as American Express International Co., Ltd. (America Express) and Diners Club Credit Card Co., Ltd. Company (Diners Club), JCB Japan International Credit Card Company (JCB), five professional credit card companies. There are also some regional credit card organizations in various regions, such as EUROPAY in Europe, UnionPay in my country, United Credit Card Center in Taiwan, etc.

In recent years, with the expansion of RMB settlement business and Chinese residents’ overseas consumption, the UnionPay organization has grown stronger and has even threatened VISA and MasterCard. They are currently using the WTO mechanism to require my country to further open up its bank card business.
