The most important thing about a credit card is the three-digit code (verification code) printed on the back of your card. You should keep it from others.
The consequences of revealing credit card passwords
What will happen if the credit card password is leaked? The "last three codes" on the back of the card is called the "second password", and foreign banks attach great importance to its confidentiality propaganda, requiring customers to properly keep their credit cards and ID cards to prevent theft. Once the customer finds that the credit card information is leaked, he should report the loss as soon as possible and reset the "last three codes".
For special merchants, there are also cases of taking risk responsibility. For example, on credit cards with signature transactions, enterprises should check whether the contents signed by consumers match the signatures on the back of their credit cards. If the cardholder fails to perform the above-mentioned audit obligations, he shall bear the legal risks arising therefrom and compensate the cardholder for the economic losses.
After the password of credit inquiry is leaked, although the credit card cannot be extracted or stolen, the information of the credit card may be leaked. Therefore, after discovering that your credit card password is leaked, it is best to reset the credit inquiry password as soon as possible.
