In general industries, swiping cards after 10 at night is easy to be targeted by the bank's risk control. It is suggested to use credit cards reasonably, because swiping cards is risky, so you can't swipe your cards at night, and the precautions when swiping bank cards.

1. Don't use this card to spend the same day after the same card fails many times;

2. Don't swipe the same card for many times on the same machine, which is easy to be recognized as a cash-out phenomenon by the bank, especially don't swipe an amount close to an integer such as 999 or 1000 1.

3. Try not to exceed 50,000 yuan for a single transaction and 200,000 yuan for a single day.

4. The transaction receipt must be kept for checking the bill in the future.

5. Check whether the amount is correct before signing the bill, and check with the other party immediately if there is any transaction error;

Suggestion:

1. When using the POS machine to swipe your card, you must ensure that the credit card is not far from your sight, and remember to deliberately block it when entering the password;

2. Take back the card immediately after swiping the card, and keep the documents properly so as to check with the statement in the future.

3. When shopping with a credit card, you should know the available balance of the credit card to avoid embarrassing situations such as insufficient balance when swiping the card.

4. It needs to be clear that the credit card of Shanghai Pudong Development Bank has no points when swiping cards from merchants such as wholesale, automobile and real estate.

5. The credit card amount does not match the merchant. For example, breakfast shops and snack bars brush thousands of pieces at a time, and convenience stores brush tens of thousands of pieces;

6. Always grab the consumption of a merchant, and the diversification of credit card consumption is not a joke. If you always rob a merchant or the same type of merchant to swipe your card, what do you think the bank will think of you?

7. The number of swipes per day is too frequent, such as brushing two or three transactions in half an hour, and it is different merchants. Unless several businesses are next to each other, it is estimated that this speed can't even catch up with the plane.

8. I just paid back the money and brushed it out. I don't know what will happen if I don't say it. Everybody knows that.
