What if the POS card is not issued but the customer receives the deduction information?

If the bank really deducts money, the customer can initiate bill adjustment to his card issuing bank. Because there was no receipt at that time, it was definitely impossible to adjust the bill, and then the bank would check the money and return it to the cardholder. Generally, no receipt is issued, and it will be returned directly to the customer card in 99% cases. If it does arrive at the account of the merchant, the merchant will return it to the cardholder.

General merchants will ask customers to brush again or pay in cash. It is because businesses generally have stores to do business, and they will not run away for a short time, and the cards are the customers' own and can be audited. The audit is not deducted, and the money paid is also right.

Merchants who use pos machines should pay attention to the fact that in order to ensure the rights and interests of funds, the receipt is a transaction voucher, and all transactions must be signed by the cardholder. If you don't issue a receipt, you won't succeed, and you must let the cardholder re-trade.

Extended data:

Because the data has arrived at the issuing bank that recorded the consumption, but the data has not been returned to the pos, the ticket has not been issued.

The actual deduction was unsuccessful. The bank collected this bill before the settlement, but under normal circumstances, the bank will find that the consumption is unsuccessful after 24 hours or 48 hours of reconciliation, and it will automatically correct it, so it will be found that the deduction is unsuccessful in a few days.

The whole transaction process of credit card swiping is as follows: 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. The communication data of any link in the middle is wrong, the transaction is unsuccessful, and the pos machine will not issue tickets.

China Merchants Bank -pos card did not receive the receipt, and the customer received the debit message.
