The bank card inexplicably received a quick payment SMS.

It may be because someone mistakenly associated your bank card with a third-party platform or company, resulting in the funds on your bank card being paid when you use the platform or company payment system. To solve this problem, you can:

1. Query bank card statement: Check your bank card statement to see if there are any transaction records related to unknown companies or platforms.

2. Contact the bank: directly contact your bank to explain the situation and provide any suspicious transaction information so that the bank can help you investigate and solve the problem.

3. Check account security: Check your account security settings to ensure that there is no security risk of being missed or used by others.
