Visa and MasterCard are world-renowned credit card brands, operated by Visa International and MasterCard Corporation respectively. Visa originated in 1976 as BankAmericard, while Mastercard was founded in 1966 and is headquartered in New York, USA. The two companies connect financial institutions, merchants and cardholders around the world through their payment systems and financial services, providing consumers with convenient payment methods and a variety of value-added services, such as personalized points rewards, emergency backup cards and travel insurance wait.

Unlike other exchanges, the American Stock Exchange focuses on financial services for small and medium-sized companies, providing stock, options and derivatives trading to help these companies increase market exposure. In the field of credit cards, Visa not only has various credit card products to meet the needs of different customer groups, including new credit card customers, high-end consumers and institutions, but also provides debit card services, such as Visa, VisaElectron, Interlink and PLUS. Debit cards provide consumers with more convenient, secure and flexible financial solutions through electronic payment methods.

Applying for a Visa or MasterCard credit card usually requires meeting certain conditions, such as a good credit record, stable job or income, and possible proof of income. Specific requirements may vary between different card issuers, and applicants usually need to fill out an application form and submit relevant documents for review.
