Precautions for credit card use?
1. When going out, don't put mobile phones, palmtop computers and other magnetic items with credit cards together to avoid magnetization; It is best not to put the bank cards next to each other to prevent the magnetic strips from interfering with each other. You know, all bank cards have a magnetic stripe that is easy to get hurt.
2. Before going out, you'd better try out whether your long-term vacation credit card can still work normally. Because some bank cards have not been used for a long time, they only remember to use them when they are away from home. It is inevitable that they will be embarrassed if they need to pay by credit card and cannot be swiped out.
3. Don't rush to swipe your card in a short time. It is easy for the vigilant banking system to think that it is a "stolen card" for fraudulent use. It is best to buy everything at once and swipe your card uniformly. In addition, it is best to know your credit limit like the back of your hand before you go out, so as not to encounter the refusal of merchants when you want to overdraw it smartly.
4. Keep the transaction slip properly. In case of repeated deduction due to cross-bank or cross-regional bank card transactions, you should contact the issuing bank in time with the transaction slip; On the other hand, if the receipt is discarded at will when withdrawing money from the atm, it will also give criminals with bank cards an opportunity.
5. After receiving the statement sent by the bank, you should check the use of the card in time. If you need to check the account, you should inquire through the customer service center within 15 days after receiving it. Because the working group of China's bank card center has clear regulations on the time for credit inquiry, once the time limit is exceeded, as usual, the issuing bank has no right of investigation and recourse against the acquiring bank.
6. If you plan to go abroad, you should apply for an international card one month in advance. Because it generally takes 12 working days to review and make, the date of sending the password will be a little later.
7. Practice your signature. When international cards are used abroad, they are paid by signature authorization, without passwords or certificates. Therefore, the first thing you should do after receiving an international card is to verify whether your name is correct or not, and you should also sign a good word in the signature column above the magnetic stripe on the back of the international card, preferably a signature that is not easily imitated by others.
8, deposit money into the card to see clearly. International credit cards belong to credit cards, which encourage consumption first and then repayment. Therefore, if foreign currencies are deposited in international credit cards first, these foreign currencies will have no interest. The international debit card saves money first and then consumes it, so the money deposited in the international debit card has short-term interest.
