What about the restrictions of Guangfa Credit Card on specific merchants?

The reason why the GDB card will receive short messages about the consumption limit of specific merchants is that cardholders who receive short messages from specific merchants often cash out on POS machines, which leads the credit card center of Guangfa Bank to find that cardholders who receive short messages from specific merchants have abnormal transactions through big data. After verifying the fact of illegal cashing or false trading, Guangfa Bank closed the transaction channel of the cardholder's POS machine after confirming the violation. The correct solution is to use mobile phone online payment to lift the restrictions on specific merchants of Guangfa Credit Card.
