2. Protect the validity period of the credit card and the last three security codes on the back.

There are four numbers on the front of the credit card, which is the validity period of the credit card. A string of numbers on the back of a credit card, the last three of which are particularly important. Domestic credit cards are spent abroad, and you don't need to enter a password. All you need is the expiration date of the credit card and the security code on the back to brush away the money.

Don't lend your credit card to others.

When issuing a card to a cardholder, the bank will verify whether it is the credit card that I applied for and stipulate that the credit card can only be used by the cardholder himself. Lending a credit card to others will increase the risk of card theft.

4. Limit the amount of consumption

Cardholders can set the daily limit of credit card consumption, and the amount will be reduced to a minimum to prevent theft. You can also set the upper limit of online transfer or online consumption.

5. Open SMS service.

Cardholders can open SMS notification service to keep abreast of changes in their credit card accounts. Once the credit card is found abnormal, you can contact the bank in time to understand the situation.
