I received a message that the GDB card transaction is abnormal and needs to be verified, otherwise the card will be closed. Is it true?/You don't say.

It's true. Recently, due to the central bank's strengthening control over financial norms, the supervised part of Guangfa Bank found a number of irregularities and frequently received regulatory fines, which led to the recent large-scale mass sending of risk control text messages by credit cards of Guangfa Bank. Guangfa classifies customers' risk control, and different risk control levels prompt different SMS contents. If you receive a text message, you should still pay attention to your card. After all, it is not groundless for Guangfa Credit Card to send you a message.
