I went to the supermarket to shop and swipe my card, but I received a short message of deduction, but the POS machine didn't print the receipt, and I couldn't find the transaction record. I paid in cash again. This is the expense deduction. This is normal, but it doesn't happen often. This usually happens because the network signal is not good. Generally, when the pos machine swipes the card, that is, after swiping the card, it will send a signal to the issuing bank to make a consumption. However, when the pos machine received the payment from the issuing bank, it didn't receive the signal from the issuing bank, that is, it didn't print out the receipt, and at the same time, the SMS of the other bank card reminded it to deduct the money. In fact, this transaction of pos machine is a failure.

In this transaction, the bank froze this part of the money because the banking system did not know whether the transaction was successful or not; When the bank conducts liquidation, the system will return the money to the bank card of the transaction by default. It takes about two days, but it's best to promise the customer a week.

If you want to check whether the transaction is successful, you can call pos merchants and card issuers to confirm the real situation. Or call the customer service of UnionPay 955 16 for inquiry. As long as UnionPay confirms the success of the transaction, the deduction will be successful. If the transaction is really unsuccessful, just wait for the money to come back.

In this case, you need to correct the previous transaction first, that is, swipe a dollar casually, and then swipe your card.
