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 the new number, and then use the card number, ID number, name and mobile phone verification code. To register on a third-party payment platform, open a fast payment by credit card to cover your money. Generally speaking, 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 logo, card number, English or pinyin name, activation date and validity period. A chip is attached to the front of the issued card.

2. Back: card magnetic stripe, cardholder's signature column, service hotline, four or all digits after the card number, and credit card security code (the three digits immediately after the four digits in the signature column on the back of the credit card 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, the credit card security code, expiration date and credit card password will not be leaked, and it is still impossible to steal the credit card with only one credit card number.

Bank card application and loss reporting

The process of applying for a credit card and a debit card is different. When handling a credit card, you need to bring your valid certificate (ID card or a copy of ID card), residence certificate, unit income certificate or personal assets certificate, and go through the relevant formalities at the bank counter. You need to fill out an application form, in which the information requested is true. After filling out the application form, you should go to the head office of the bank for the record. It will take about 20 working days to issue cards to customers after the head office of the bank examines the application materials. Handling debit cards is relatively simple. You just need to bring your own valid documents, mainly your ID card, fill out the application form at the bank where you open the account, and then you can issue the card to the applicant.

The reporting procedures of major banks are not exactly the same. If you lose it, you can temporarily report it by phone or online banking, and then bring your ID card and other supporting materials.
