The correct use of POS machines, many people are mistaken

There are more and more people using POS machines now, but many people's operations are wrong. The following small series tells you the correct operation method:

Before turning on the POS machine, check whether the power is turned on and whether the link between the printer and the host is normal.
2 shutdown check
After properly closing the POS machine, it is necessary to check again for damage.
3 small ticket printing
If the purchase order is not printed, the purchase order can be printed from the beginning. If you can't print, you should select the inquiry and buy and sell at the time. Check whether the sale is over. Check the purchase and purchase serial number. Do not repeat the card to prevent the cardholder from repeating the payment. .
4 pressure sheet needs to be cautious
If the card is not valid, the card issuing bank will not recognize it: the debit card and the member card that has not signed the card pressure agreement, the handling of the bill should be cautious!

7 do not plug the communication line
The communication interface of the POS machine is a dedicated interface, which is not mixed.
8 full or partial returns
If the return is not successful, do not arbitrarily refund the cash or let the cardholder take the goods, you can do the corresponding treatment according to the POS prompt or contact the bank maintenance personnel.
Remember to have the cardholder sign the purchase order and note that the cardholder's signature is the same as the name on the reverse side of the card. The type of purchase and sale on the purchase order also needs to be carefully reviewed to prevent the formation of wrong accounts! Once the sale or error or credit card theft is detected, the sales and purchase documents can be used as evidence to prevent trouble!
The popularity of POS machines and credit cards has facilitated all aspects of our lives, but we should know more about and familiar with POS and credit card related security knowledge. It is recommended that friends know more about the standard process of POS receipts and the security knowledge of credit cards. After all, there are too many black technologies for unscrupulous people, which makes them hard to guard against.

Circle SAD Therapy Lamp

Many people eat and sleep a little in winter and hate dark mornings and short days. This is called "winter blue". Others have more serious symptoms such as sleep disorders, withdrawal symptoms, binge eating, depression, anxiety, and lethargy. These often lead to family, work, and relationship difficulties. This is a perceived problem called seasonal affective disorder (SAD).
SAD is caused by a lack of bright light in winter. The light that enters our eyes stimulates our brain and controls our daily rhythm through the production of hormones. For some people, winter does not have enough light to regulate the hormones that prevent us from getting up and sleeping, being energized, and depressed.
