How about bank card SMS? How to identify the source of funds?

Text messages can't tell the source, so you can only check through online banking or go to outlets.

Specific inquiry process: 1 mobile banking inquiry: log into personal mobile banking account and enter "My Account-Inquiry Details". Generally, income, such as salary, will be marked, and the funds refunded by the platform will also be marked; 2 business outlet inquiry: directly bring personal ID card and bank card to the bank outlet for inquiry; 3 online banking inquiry: log in to personal online banking and enter personal debit card account.
