I received a message saying that I swiped my card from a pos machine and I didn't spend it myself! What should we do?

First, this situation belongs to transaction interruption, that is, communication is interrupted during the transaction, or the server temporarily fails. Although the customer received the SMS to deduct the fee, you don't know whether the transaction was successful or not. Don't let customers leave before confirming the success of consumption.

Second, the solution:

65438+ This situation may be that the printing function of the POS machine failed at that time.

2. You can call the 24-hour service hotline of UnionPay at 955 16, and choose the manual service, and report the merchant name, merchant number, terminal number and customer * * on the purchase order you brushed before to the UnionPay staff, so that the UnionPay staff can help you check whether the customer's card has been successfully spent in your store or company. If you get a positive answer, then you can rest assured that the customer will leave. Otherwise, the customer will be charged again. If the customer doesn't trust you, you can ask the customer to call UnionPay for verification. After verification, you can swipe your card if you want to spend again.

3. Due to communication interruption, the money on the bank card will be deducted immediately when swiping the card, so the bank will immediately deduct the money on the customer's card when swiping the card, and then the bank will send a message to the customer immediately after deducting the money, and the customer will receive a text message. The reason for the unsuccessful consumption after bank deduction is that the data link with UnionPay server is needed after bank deduction, that is, this step is interrupted and data link with UnionPay cannot be carried out. So the transaction is interrupted, and the data will be returned after the interruption, so the transaction is unsuccessful. In other words, the customer will receive a refund message from the bank.

Extended data

Credit card reader is referred to as POS terminal for short. The terminal dials through the telephone line to send the information to the UnionPay platform. After the platform of UnionPay recognizes the relevant information, it will send the deduction information to the issuing bank, and the issuing bank will send the information back to the platform of UnionPay after confirming it. After confirmation by UnionPay, the processed information will be sent to the front-end terminal, and the terminal will print the documents after receiving the confirmation information. Mobile POS terminals send and receive information through data signals based on the same principle. The communication fee is not much, and the fixed terminal communication fee is charged by the telecom company according to the local telephone standard.
