What's wrong with invalid display of ore pool

1. Hello, there are four main reasons for this situation:
1. The POS secret key is lost
2. The merchant's information does not exist in the bank background
3. The merchant changed the flow card in the POS independently
4. Illegal operation is blocked
notes:
first, when swiping the card, the card owner must not let the card out of his sight, especially pay attention to whether the other party swipes two machines. The normal POS machine will not import the card information, but the swindler will take advantage of the "greasy machine" in the above case
secondly, many people are greedy for convenience when they swipe their cards, especially when they have meals, and they are too lazy to leave. Instead, they will tell their cards and passwords to the waiter and let them swipe by themselves. These people will think: anyway, there are SMS reminders, brush more I will know. So, will this case make you sober up and stop swiping your card like this
Third, develop a good habit of consumption. Use different bank cards for "in" and "out". Never use your salary card directly. Try to use credit card or standard credit card for consumption
fourthly, if not necessary, the credit card limit should not be set too high to avoid large losses.
