Credit card, also called debit card, is a credit certificate issued by a commercial bank or credit card company to eligible consumers. It is a card with name, expiration date, number and cardholder's name printed on the front, and a magnetic stripe and signature strip on the back. Swiping a card on a POS machine is the most common way to use a credit card, and it is also a way to swipe a card online. When swiping a card, the operator should first check the validity period of the credit card and the cardholder's surname. Then, according to the issuing bank and the currency to be paid, select the corresponding POS machine, draw the magnetic stripe of the magnetic stripe credit card on the POS machine, or insert the chip credit card into the card slot, connect with the payment gateway such as the bank, and input the corresponding amount. After the remote payment gateway receives the information, the POS will print a receipt (at least two copies) for credit card payment, and the cardholder should sign the receipt after checking that the information on the payment receipt is correct. After checking the signature on the receipt and the signature on the back of the credit card (including the complete name matching and the basic handwriting matching), the operator sends the credit card copy and the credit card payment receipt to the cardholder. At this point, the credit card swiping program on the POS machine is completed.
Credit card installment payment refers to the business that when a cardholder uses a credit card to make a large amount of consumption, the issuing bank pays the consumption funds of the goods purchased by the cardholder to the merchant in one lump sum, and deducts the consumption funds from the cardholder's credit card account in stages according to the cardholder's application, and the cardholder repays the money according to the monthly recorded amount. In the past, credit card installment mainly included bill installment and single consumption installment, and banks usually charged corresponding handling fees according to the number of installments. Whether it is bill installment or single consumption installment, the premise is to generate consumption behavior first, and then the bank will set installment repayment for the generated credit loan. Mail order installment means that the cardholder receives the installment mail order catalog manual sent by the issuing bank and chooses from the limited goods. Then the bank orders in installments through online installment mall, telephone or fax installment application form, etc. Generally, there is no handling fee for mail order installment regardless of the number of installments. However, due to the long ordering cycle and relatively complicated return, it is recommended to compare before buying.
