POS is a multifunctional terminal. It can be installed in special merchants and acceptance outlets of credit cards, and connected with computers to realize automatic transfer of electronic funds. It has the functions of supporting consumption, pre-authorization, balance inquiry and transfer, and is safe, fast and reliable to use. It is difficult to obtain basic business information for bulk transactions, and the introduction of POS system is mainly to solve the blind spot of retail information management. An important part of chain branch management information system.
Points for attention in the use of POS machines:
1. Before using the POS machine, it is necessary to check whether the power supply is connected, whether the printer and the host computer are connected normally, and whether the POS printing paper is installed.
2. At the end of business every day, the operator should perform "day-end treatment". It is especially important to note that when the POS machine needs to be replaced for some reason, it must be turned off and replaced after the "day-end treatment" is completed.
3. Don't charge the cardholder repeatedly because of repeated swiping. During the transaction, if the purchase order is not printed, the operator should first select the "reprint" function; If the voucher cannot be printed after re-printing, he should select the function of "Query Current Transaction" to query the batch number and merchant serial number of the transaction, then turn off the power supply, check whether the printer is connected correctly, and select to print a specific record for processing after re-plugging.
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 reversed. If the reply is really successful, you can copy the consumption elements on the POS consumption list, and the cardholder can take away the goods with his signature or cancel the transaction. Don't swipe your card again at will to redo the transaction, otherwise it will deduct the account for the cardholder repeatedly.
4. If you fail to swipe your card during the transaction, you need to press the required transaction code key again to avoid mistaking other transactions for "consumption" and causing repeated deductions.
5. Enter the cardholder's password. In order to ensure the security of transactions, cardholders need to enter the correct bank card password when they trade at public POS machines. If the cardholder's bank card has no reserved password, the operator directly presses the "OK" key of the POS machine to conduct the transaction, and the transaction is successful.
6. Don't forget to ask the cardholder to sign the shopping list. If the cardholder's signature is inconsistent with the reserved name on the back of the card or the letter of the name on the front of the card, you can check with the issuing bank.
7. The transaction type on the printed purchase order should be carefully reviewed to avoid changing "consumption" into "pre-authorization" or "return" into "consumption", resulting in wrong accounts.
8. Return transactions can be returned in whole or in part. If the return is unsuccessful, do not refund the cash or let the cardholder take the goods at will. You can handle it according to the POS prompt, or you can contact the maintenance personnel of UnionPay.
9. Don't just plug in the communication line. The communication interface of POS machine is a special interface (line port), so don't confuse each other.
10. For debit cards and cards of member banks that have not signed a manual card pressing agreement, the card pressing transaction is invalid and the issuing bank will not recognize it. Therefore, do not accept pressing cards.
