What you want to ask is the reason why China Merchants Credit Card swiped it after 12: 00 and said it was not in the business hall. Business hours limit, credit card system update or maintenance.

1. Business hours limit: China Merchants Bank accepts credit card payment within a certain period of time, and refuses credit card payment outside business hours to ensure normal business and service quality.

2. Update or maintenance of credit card system: In a certain period of time, China Merchants Bank will update or maintain the credit card system, which makes it impossible to pay by credit card normally.
