Many card friends accidentally let others know the credit card number, and they are worried that the card number will be stolen if it is leaked. If only the credit card number is known by others, and other information, such as credit card expiration date, CVV2 code and credit card password, is not leaked, there is no need to worry at all. There are many kinds of credit card information, including credit card number, cardholder's name, credit card password, CVV2 code, expiration date and mobile phone verification code, among which CVV2 code, expiration date and password are the most important. If others know this information, they will probably steal your credit card. And if it is only known and other information is not leaked, it is impossible to steal credit cards only by the card number. Of course, if you really don't feel at ease, you can report the loss of your card and replace it. After reporting the loss, the bank will send you a new card. The card number of the new card is different from that of the old card, so you can continue to use it with confidence. Although the credit card number will not be stolen, everyone should protect the relevant information of the credit card when using the credit card, especially the CVV2 code, which is the most important voucher for online transactions and a voucher for verifying the identity of the cardholder. so, how to avoid credit card information disclosure? 1, first of all, through the formal channels to do the card, and properly keep the personal credit card and password. 2. When using pos machines, don't let the credit card leave your sight, and don't hand it over to the service staff. 3. Check whether there are suspicious devices in the pos machine, credit card slot and service personnel's hands, and cover them when entering the password; 4. Keep the mobile phone with credit card information properly, and try not to sell the replaced second-hand mobile phone. 5. Shop on regular websites, because informal websites are likely to set up programs to copy your information directly. 6. Less cash-out behavior, especially those who don't even know their origins, will run to cash out, and it is very likely that they will set themselves in.

what should I do if I accidentally reveal information other than the card number? If someone accidentally knows the CVV2 code, credit card password and other information of the credit card, the safest way is to call the first time to report the loss of the credit card and make up the card. If the operation is timely, it can effectively avoid the loss of the credit card being stolen. It should be reminded that most banks are not free to report the loss of credit cards, and they need to pay a replacement fee of about 2-5 yuan. After the replacement card is successful, the fee will be deducted directly from the credit card limit. After receiving the new card, you must pay attention to the bill. If the card replacement fee is deducted and the bill is issued, it must be repaid on time, so as not to affect personal credit beyond the time limit.
