The customer paid by credit card scanning code, but Lacarra pos machine did not issue a receipt, and the customer showed that it had been deducted. What's going on here?

The whole transaction process: the pos machine swipes the card/scans the code-the data goes to the UnionPay center/network link-the issuing bank-returns to the UnionPay center/network link-returns to the pos machine to issue tickets.

The following is a complete process:

There is an error in the communication data of any link in the middle, and the transaction is unsuccessful. po triggered the short-selling system of the bank and has returned to the reverse.

Let me tell you a little trick first.

Tip: Merchants often encounter POS machines to purchase tickets by swiping their cards, but the customer's mobile phone receives a debit reminder message from the bank. In this case, please don't feel confused and panic about a UnionPay card:

1. Inquire on the POS machine, and the POS machine will prompt "Automatic correction succeeded". At the same time, the cardholder will also receive a short message from the bank, indicating that the deduction has been returned to the account.

2. The Chamber of Commerce will return to his card immediately.

Why did you receive the text message but didn't get the pos receipt?

First, the straightening time is 48 hours, and it won't run for a day or two.

Second, the consumer cardholder can initiate bill adjustment to the bank and not approve this consumption. Moreover, the merchant can't provide the pos machine purchase order and certificate, and the bank won't admit that 100% deduction is unsuccessful. Because of this, funds must be safe.

Scan the code and get no receipt:

1. Confirm whether the cardholder has received the complete tap water at the first time.

2. Transactions with successful code scanning are subject to the deduction process. If the cardholder receives the complete Alipay/WeChat debit flow, under normal circumstances, the money will be credited in the normal settlement cycle. At the same time, if there is no receipt for scanning code transaction, it is recommended to reissue the receipt as much as possible and keep the debit note received by the cardholder.
