the visa logo on the credit card means that this credit card supports the visa channel for credit card spending, which is usually spent through the visa channel abroad.

visa is an international credit card organization, whose Chinese name is visa. It was first issued in 1976, and now visa cards are often used abroad, but not in China. Because China has its own credit card organization called "UnionPay", users can take out their own credit cards or debit cards and generally see the logo of UnionPay.
