Is it true that the bank sent a warm reminder?

Generally, the warm tips at the beginning are low-risk risk risk control information, which can be ignored first.

However, if you receive warning information or obvious risk control information, you should pay attention and start thinking about whether there is something wrong with your credit card. For example, it is best to find out which machine is out of order.

Generally speaking, if you swipe your card on the same machine for a long time, it is easy to be marked by the bank. If you can find out which machine is out of order, don't use this card and machine yet. If you swipe your card frequently, you will inevitably be suspected.
