If you accidentally reveal your credit card number and "last three codes", I suggest you stop using this card. You can directly call the bank customer service center to cancel, and then apply for a new card. Once the credit card information is leaked, it is easy to be stolen by others. Although banks have lost their card protection service, it is generally difficult to get compensation if there is no positive evidence to prove that they have not swiped their cards. That is, if someone steals it, you have to pay your own debts.

If you have applied for a credit card before, it won't be so difficult to apply again. Generally speaking, the speed of auditing and issuing cards is relatively fast.

Please note the following when applying for a new card:

First, don't reveal the "last three codes" of the card: the last three security codes on the back of the credit card and the dynamic verification code of the credit card are important vouchers to authorize fast online payment, while the three security codes on the back of the card are almost equal to the password. Don't disclose your dynamic verification code and card security code to others. You can scrape off the security code with a tool or stick it on with opaque tape.

Second, protect personal information: banks will not ask customers to provide personal information on the phone. When a cardholder receives a phone call or a short message asking for personal information such as card information and personal identity information, he can call back the bank customer service phone on the back of the credit card for verification. Don't trust "area code+955 ××××" or unfamiliar phone numbers.
