The two premises have no impact. POS machines are launched by payment companies with formal payment licenses. It cannot be the so-called low-interest-rate POS machine of an unscrupulous payment company but with code skipping. Every purchase is from a real merchant and has no impact on the credit card. Moreover, for users with good usage habits, the card limit may be increased.

: The flow of funds after the credit card is swiped:

1. First, it all flows into the UnionPay reserve account. On the second day, that is, after the second working day, these accounts will settle the amount to the merchant at the POS machine. This is actually like a wall, blocking all information between the two parties. That is to say, the credit card issuing bank and settlement bank cannot contact each other, and they have no way to see each other's transaction information. Generally speaking, the POS machine will automatically assign a merchant to us, that is, the system will automatically match us after swiping the card. Generally speaking, they are merchants with points, such as the well-known catering industry, entertainment industry, hotels and other merchants. This will be of great help to Ting'er, because the information received by UnionPay and the bank shows that the consumption of these cardholders is real consumption, and the points are very high, so it is of great help to Penguin. big. In this case, you don’t have to worry about this or that at all, just take the card and swipe it.

2. Credit cards belong to bank cards, but POS machines belong to a third-party payment company, and the information between the two does not flow. In other words, the bank cannot see who is the owner of the POS machine, and the payment company does not know who the cardholder is. So it is absolutely no problem to use your own POS machine to swipe your own credit card. But when you swipe your card, you must remember something like this: when looking for a machine, you must look for a machine that clears the card, and you must not look for a machine that jumps codes randomly. That would be very harmful. For example, if you sometimes spend money here, your bill will show up as spending money there, and this problem will arise. For example, if you sleep in a hotel all night, but the bill shows that you also consumed a certain amount of medicine in the hospital, this seems very wrong, so it is better not to do this as much as possible to avoid any consequences. Don’t let the bank’s risk control system catch you for unnecessary risks.
