What if the credit card password is seen? Do I need to change my password immediately? I still have my credit card. Can someone really use my credit card to swipe it? How can he swipe his card without it? What other security risks will exist? How to solve this problem better? 1. You can swipe your credit card account and password without a card. Others know your account and password, but you still have the card. Can the other party spend it? Some netizens said that it is not enough to change the password. Besides, there is nothing the other party can do if they only know the password. But is it really okay? Now there is a technology called copying, which copies all the information on your card to you and makes an identical card, so you can spend it. It is not unheard of that the stolen credit card is a cloned card. Some banks (such as Bank of China) can pay by phone or online as long as they know the card number, expiration date and CVV2 code on the back of the credit card. Some banks' credit card online payment requires that they must sign up at the counter in advance to open online banking. As long as there is no online banking, or the information of online banking is not leaked, the other party cannot succeed through online payment. But telephone payment is still dangerous. In addition, the other party can contact the credit card customer service center and use the information described in the mastered questions to successfully pass the identity verification of the customer service staff, report the loss and reset the password. At this time, even if only you master the original credit card password, this password has been invalidated. You don't know the newly set password, and this credit card in your hand can no longer be used for credit card transactions. Or, if the cardholder has not used the card for a long time and has not aroused vigilance, the other party can also modify the cardholder's contact address and telephone number through the credit card center to report the loss or reissue the card. In this way, even if the other party can't copy the credit card, they can get a new card from the bank and spend it at will!

2. What should I do if the account number and password of the credit card are known? If the account number and password of the credit card are known, 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. You can call customer service and change the password; You can also log in to official website and change your password yourself; And bring your own documents to the outlets to modify, don't be lucky, be sure to modify the password in time and as soon as possible! The most important thing about a credit card is the three-digit code (verification code) printed on the back of your card. It should be hidden from others.
