The correct credit card amount should be 19850, 36840 to brush, and some also like a card to divide a few small brush, such as 1500, 2500, 2000 even brush, this is not acceptable.
2. The monthly brush of the POS machine can't exceed 3 million. Although some POS machines can brush 100,000 on a single pen, the daily brush is unlimited, but it is not called to brush hundreds of thousands every day. You can't put all the cards because the rate is low. They are all used on a machine to brush, so that the bank computer control system alarm will be red, when UnionPay will first check those machines with a large amount of cards, if it is a normal business, then naturally no problem, but if not, then You are going to spread things up. The best thing is that a machine is controlled at about 1 million. If you don't have enough brush, you can apply for a few.

If you have been swiping your credit card from start to finish, then unfortunate things will happen. UnionPay will check your card records and find that suspicious will stop settlement until the problem is solved.
4. It is best to sign the small ticket, do not sign it, in case the order is made, the handwriting on the small ticket is found by the same person. Even if you have a normal business, he will think that you are helping others to cash out. Small tickets are best kept for more than half a year.
5. The most important point is that due to various reasons, the card fails. If you have such a problem, after you have brushed it twice, you should not brush it again if the transaction fails.
