Card friends have been very upset recently. If they accidentally reveal the credit card number to others, they are afraid that others will use this card number to steal credit cards. Under normal circumstances, you can't swipe your card only by credit card number, so Xiao Wu actually doesn't have to worry at all, because there are other conditions for credit card swiping. Let's take a look at it.

1. Is it risky to know the credit card number?

In general, there are many kinds of information on the face of a credit card, and the card number is just one of them. If you accidentally let others know the card number, but he doesn't know other information, your credit card is still very safe.

1. Front: name and logo of the issuing bank, credit card type (organization logo) and holographic anti-counterfeiting mark, card number, English or pinyin name, activation date and expiration date. The chip is attached to the front of the newly issued card.

2. Back: card magnetic stripe, cardholder's signature column, service hotline, the last four digits of the card number or all the card numbers, and credit card security code (on the signature column on the back of the credit card, the three digits immediately after the last four digits are used for TV, telephone and online transactions, etc.).

in the process of using a credit card, as long as the card is in hand, and the credit card security code, expiration date and credit card password are not disclosed, it is still impossible to steal the credit card with only one credit card number.

second, what if the credit card number is known by others?

If only the credit card number is known by others, it should be all right, but you should make sure that the validity period of the credit card and the three-digit security code are not known by others. If these have been leaked, it means that your credit card has great security risks.

If the account number and password of the credit card are known by others, you should change your inquiry password as soon as possible. Avoid others using the ID number to report the loss of the mobile phone and reissue a new number, and then use the card number, ID number, name, mobile phone verification code, etc. to register on the third-party payment platform and open the fast payment of your credit card to cover your money.

There are many specific ways to modify the password. You can call customer service to modify the password, or log in to online banking to modify it yourself. If the security code is leaked, as long as the password is modified in time, it should be no problem.
