Sometimes when we finish the POS machine, we will receive the following reminder. Do you think about whether you have received it?
Why is a credit card facing such a danger when I brush a pos machine?
Because the pos machine you brushed affects the interests of the bank, it is discovered by the bank that it will naturally take measures to protect its own interests, that is, it will be closely watched by the risk control system or even deducted from the card.
