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 bank, and input the corresponding amount.

After receiving the information of remote payment, POS will print a credit card payment receipt (at least two copies), and the cardholder will 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 full name and basic handwriting), the operator sends a copy of the credit card and the credit card payment receipt to the cardholder.
