Therefore, regardless of whether they have a credit card, citizens should keep their ID cards and related information, such as name, birthday, ID number, home phone number, address, marital status, family members, education, occupation, etc. And don't disclose relevant information to others easily. When you receive a call claiming to be a bank employee, you should verify the identity of the other party or call the customer service phone designated by the bank to handle the business.
At the same time, because the credit card has the function of fast payment, the validity period of the card and the CVV password on the back of the card are very important information. Don't disclose this information to anyone.
Secondly, credit card consumption should check the consumption amount and card number. Check the consumption amount and card number before using the POS machine to swipe the card for signature. After the transaction is completed, it should also be confirmed that the credit card returned by the cashier is the person, in case it is "replaced".
When you apply for a card, you should set a password and sign on the back of the credit card. Many cardholders feel that the signature on the back of the credit card is dispensable, and the signature is mainly to verify the identity of the cardholder and ensure the safety of the cardholder's card use. At present, the common method of stealing credit cards is copying, but scammers usually steal the information in the magnetic stripe and the transaction password of swiping cards through some technical means, so it is difficult to accurately imitate the cardholder's signature. If there is a signature on the back of the card, it can effectively avoid the loss of duplicate cards.
If you lose your credit card, you should report it to the bank in time. If the credit card is lost or swallowed by ATM, you should report the loss to the bank in time. Don't trust the announcements or notices posted near the ATM, and contact the bank customer service if necessary.
