I swiped my card on the credit card machine, and the message of successful transaction was swiped on the card, but the other party didn't receive the money, and there was no money in my card. What should I do? You can check whether the credit card machine has issued a receipt. If the receipt is issued successfully, the transaction is successful. Just wait. The whole transaction process of credit card swiping is: credit card swiping by pos machine-data going to UnionPay center-issuing bank-returning to UnionPay center-returning to pos machine to issue tickets.

This is a complete process. There is an error in the communication data of any link in the middle. Even if the transaction is unsuccessful, the pos machine will not issue a ticket. The process of swiping the card only triggered the short message system of the bank, but it has returned to the clearing system.

Since the data has arrived at the issuing bank, the issuing bank recorded the consumption, but the data was not returned to the pos, so the actual deduction was unsuccessful, so the pos sign was not issued. This account will be automatically reversed when UnionPay closes, so you should check with the issuing bank at least 24 hours later, and you will find that the money has been returned.

POS machines must be connected to the network of UnionPay to trade. Different connection methods produce different types of POS. This can be understood as making a phone call. POS with telephone lines is the majority, just like telecommunications is the most common; It is a mobile POS using mobile GPRS network, just like a mobile phone can be carried with you. Even the computer is called MISPOS, which is set up to facilitate the unified management of many POS by large businesses, and is not used by ordinary businesses.

The resulting cost is the communication fee, and it doesn't matter if the merchant pays for the telecom mobile. UnionPay has a subsidiary called UnionPay Business, which is responsible for providing and installing POS machines and hardware maintenance of the machines. We can apply to it to install the machine, and we don't have to spend money on future maintenance unless it is damaged artificially.
