Usually, for the purpose of protecting and maintaining the security of customers' accounts, banks ensure that customers' personal information will not be stolen or used improperly.

China Merchants Bank usually asks customers to confirm or update personal information, such as account number, password, ID number and other sensitive information, by sending short messages, emails or phone calls to customers. This is a common security verification measure used by banks to ensure the safety of customers' accounts and funds.

If you receive the information required by China Merchants Bank to verify the account-related information, customers should be cautious, pay attention to verifying the authenticity of the information source, and prevent being cheated by phishing websites and other online fraud means.
