The reason why the bank sent a message to remind customers to use credit cards in a standardized way was that customers had previously used bad cards, which led to an increase in account risk, so the bank made a risk control warning.

when using a card, you should pay attention to swipe your card in a large store rather than a small store, because if the POS machine is not regular, it is likely to jump the code, which will lead to a further increase in account risk, and the bank is likely to carry out risk control.

In addition, it is suspected to cash out, such as always swiping the card from the same merchant and the same POS machine, always swiping the card in the middle of the night, early morning and other non-merchants' regular business hours, and often swiping a large sum of money, so this kind of risky operation should also be avoided.

when customers repay, it's best to pay off the bill in full, not always the minimum repayment. After a large amount of consumption, they can properly handle the installment (but not frequently), and the installment time should not be too long. Generally, it is only 3 to 6 installments.

Eight rules for the correct use of credit cards:

Rule 1: Be sure to cherish your credit limit and never default on the bank's money, because the bank's money can't be delayed for a minute. It's better to repay more early than to default on the bank. If the credit is delayed, the credit will be reduced, which will cause a lot of trouble.

Rule 2: Cardholders should not apply for a high-value credit card just because they have a car and a house. If they don't contribute to the bank, the bank will not give you a high-value credit card for the first time (except in special circumstances), and the high-value credit card will gradually increase depending on your credit and card usage.

Rule 3: Try to control your own consumption, and try not to withdraw cash by credit card or make investment with the money in credit card, because the interest and handling fee for withdrawing cash by credit card are very high, and it's okay to make money by investing. In case something goes wrong, how can you pay back the money in credit card?

Rule 4: The money in the credit card can be used in many ways, not just one item; Usually form a good habit of swiping the card, regardless of the amount, but it is best to swipe the card less or not, or it can be phased appropriately, which will help to increase the quota.

Rule 5: Don't trust the promotion or intermediary of handling high-value credit cards at will, which will cause risks to credit cards and information leakage and theft.

Rule 6: It is recommended that cardholders apply for a card as early as possible, and don't think of applying for a credit card until they have no money, so banks generally won't handle it for you.

Rule 7: Deal with the right opportunity. Don't be too picky about choosing a bank, because if you miss the reasonable opportunity, you may not meet the requirements when you want to deal with it.

rule 8. for credit card repayment, cardholders must learn to use multiple repayment methods. in case of problems with the commonly used repayment methods, cardholders can try another repayment method, which can avoid unnecessary credit problems.
