1. Protect your ID card information from being leaked

Everyone has an ID card, which contains our unique ID number, profile picture and other information. Protect your own ID card information can prevent credit cards from being used fraudulently and reduce the risk of fraud.

2. Protect the validity period and the last three-digit security code on the back of the credit card

There are four digits on the front of the credit card, which is the validity period of the credit card. There is a series of numbers on the back of a credit card, with the last three digits being particularly important. When using domestic credit cards to make purchases abroad, you do not need to enter a password. You only need the expiration date and the security code on the back of the credit card to withdraw the money.

3. Do not lend your credit card to others

When the bank issues a card to the cardholder, it will verify whether it is the credit card applied for by the person who applied for it. At the same time, it is stipulated that the credit card can only be used by the cardholder himself. If you lend your credit card to others, the risk of fraud will increase.

4. Limit the amount of consumption

Card holders can set a daily limit on the number of credit card purchases and the amount of each time to minimize losses in case of fraud. You can also set upper limits for online transfers or online consumption.

5. Activate SMS service

Cardholders can activate SMS notification service to learn about changes in funds in their credit card accounts at any time. Once you find something unusual about your credit card, you can contact your bank promptly to learn about the situation.
