Urgent need [hotel front desk card POS machine specific operation process and use precautions? ] The more detailed the better.

There is a paper jam in the wild card POS machine, so it can't be reprinted. It can only be reprinted after typing.

(A) the correct operation 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 conducting transactions in public POS. If the cardholder's bank card does not have a password reserved, the operator directly presses the "Confirm" button of the POS 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 the pressure card.

(2) properly keep the POS machine.

1. Don't open the POS machine shell.

2. Don't put the POS in a damp place, and don't clean it directly with liquid or spray.

3. Don't use the mobile phone connected to the POS during the transaction.

Please don't turn off the POS machine during the transaction.

5, mobile wireless POS don't use or replace the battery in flammable and explosive environment.

6. Mobile wireless POS may cause interference to wireless communication equipment during use.

7. The built-in battery of 7.POS machine is rechargeable. When removing the battery pack, make sure that the metal contacts of the battery do not touch any other metal objects.

8.POS should be operated on a fixed and stable table. If it is manual operation, be sure to hold the equipment tightly. Equipment falling may cause serious damage to the equipment.
