In terms of credit cards, visa is a payment network, similar to other payment networks such as MasterCard and UnionPay. The visa card can be used for both online and offline transactions and can be used at merchants and ATMs around the world. Visa cards have a high acceptance rate and are widely used around the world.

Visa cards are divided into two types: debit cards and credit cards. Debit cards require funds to be deposited before they can be used, while credit cards are used for consumption based on the credit limit. The visa card is very convenient to use. You only need to swipe the card on the merchant's card swiping machine to complete the payment, or withdraw money at the ATM machine.

In addition to being used at merchants and ATMs, visa cards can also be used for online shopping and overseas travel. When shopping online, consumers only need to enter the card number, expiration date and 3-digit security code to complete the transaction. When traveling overseas, the visa card acceptance network covers many countries and regions around the world, making consumption and withdrawals convenient.
