1. Before using the POS machine, check whether the power is turned on, whether the printer and the host are connected properly, and whether the POS paper is installed.
2. The operator is finished at the end of the day, and should perform day-end processing. Pay special attention to the fact that if the POS machine needs to be replaced for some reason, it must be finished after the end of the day before it can be shut down for replacement.
3. Do not repeat the debit of the cardholder due to repeated card swiping. During the transaction, if the purchase order is not printed, the operator should first select the reprint function. If the reprint cannot be printed out after reprinting, the current transaction function should be queried, the batch number of the transaction and the merchant serial number should be queried, and then Power off, check if the printer is connected correctly, and then re-plug and select to print specific record processing. If you still can't print, check the balance on the POS machine, and then check with the UnionPay Customer Service Center whether the transaction has been corrected. If the reply is indeed successful, you can copy the consumption elements on the POS consumption order, and the cardholder can take the signature. The goods can also be revoked. Do not arbitrarily re-do the transaction again, otherwise the cardholder will be debited repeatedly.
4. If the card fails to be made during the transaction, you need to press the required transaction code button again to avoid other transactions being mistaken for consumption, resulting in repeated debits.
5. Enter the cardholder password. In order to ensure the security of the transaction, the cardholder needs to input the correct bank card password when the public POS machine is trading. If the cardholder's bank card has no reserved password, the operator directly presses the pos machine confirmation button to conduct the transaction, and the transaction is successful.
6. Don't forget to let the cardholder sign the purchase order. If the cardholder's signature is inconsistent with the reserved name on the back of the card or the positive name of the card, you can check with the issuing bank.
7. The type of transaction on the printed purchase order should be carefully reviewed to avoid pre-authorization of the consumption, or to make the return into consumption;
8. The return transaction can be returned in full or in part. If the return is unsuccessful, do not refund the cash at will or let the card holder take the goods away. You can do so according to the POS prompt or contact the UnionPay maintenance personnel.
9. Do not plug or unplug the communication line. The communication interface of the POS machine is a dedicated interface (line port), which cannot be confused with each other.
10. For the card of the debit card and the member bank that has not signed the manual pressure card agreement, the card transaction is invalid, and the card issuing bank will not recognize it. Therefore, do not accept the order.
