There are still many places to pay attention to in the use of China Merchants Bank credit cards. If you don't understand, you will regret something. What should China Merchants Bank pay attention to in the safe payment of credit cards?

1. Don't scan the QR code easily.

Bank credit cards are "consumed" for no reason. One of the more common reasons is that consumers inadvertently scanned some QR codes, some of which were conducted by fraudulent means. It is these two-dimensional codes that fraudsters use to implant mobile Trojans into victims' mobile phones and automatically extract relevant information. In just a few seconds, private information such as mobile phone number, card number and password may be passed on to others.

2. Pay attention to protecting passwords and personal data.

It is recommended to change the chip card at the bank. Chip cards are more secure than traditional magnetic stripe cards, and a small piece can hold many functions, which can effectively prevent theft and cloning. Moreover, once the traditional magnetic stripe card passes through ATM or POS machine, it will leave magnetic stripe information. At present, chip card has become the development direction of international general financial card consumption.

Bankers suggest that customers should change their transaction passwords from time to time, whether overseas or at home, including for security reasons. Since the password is the key factor to ensure the security of the funds in the card, any transaction using the password is regarded as the cardholder's own doing.
