There are three kinds of bank accounts, one is a full-featured account with no limit, and the other is a limited account with a daily payment of no more than 1 10,000 and an annual cumulative amount of no more than 200,000. Third, the electronic account, without a card, must be bound under the first type of account, and the account balance should not exceed 1000.

Credit cards are organized by card, such as UnionPay, VISA, MasterCard, JCB, etc. , and the card organization will settle its credit card separately. The so-called single-label card is a credit card with only one card organization logo. The most common RMB card is UnionPay's single-label card. If it is a double-label credit card, it can be used in both card organizations.

The advantage of a single-label credit card is that it is free of currency conversion fees. Using UnionCard with single logo overseas can directly realize consumption or withdrawal in local currency, deduct money from RMB account, and avoid currency conversion fee accounting for about 1%-2% of the transaction amount, without bearing the risk of exchange rate loss and exchange rate fluctuation during currency conversion.
