Points for attention of POS card swiping
Try to avoid buying and selling in tens of thousands of integers, such as 1W, which can be 9950 or10/50 (generally speaking, there are few exact integers in normal transactions). Of course, it doesn't matter if you brush the integer twice at a time. Don't brush the integer amount frequently, otherwise the bank will judge that the user has violated the rules maliciously.
It is recommended that you swipe your card for safety reasons, and control the single transaction within 3W and the single-day transaction within 10W (above 10W, it is easy to be supervised). Of course, the premise of meeting this condition is that the user has such a large credit card.
