Use

Credit cards are usually only used by the cardholder himself. Lending them to others is generally a violation of the use contract.

Swiping cards at POS machines

Swiping cards at POS machines is currently the most common way to use credit cards, and it is a way of swiping cards online. When swiping a card, the operator should first check the credit card's validity period and cardholder's last name and other information. Then, select the corresponding POS machine according to the card issuing bank and the currency type to be paid, and slide the magnetic stripe of the magnetic stripe credit card on the POS machine, or insert the chip credit card into the card slot, connect to a payment gateway such as a bank, and enter the corresponding amount. . After the remote payment gateway accepts the information, the POS will print out a receipt for payment by card (at least two copies). The cardholder should sign the receipt after checking that the information on the payment receipt is correct. After the operator checks the signature on the receipt and the signature on the back of the credit card (including that the name completely matches and the handwriting basically matches), the operator gives the credit card and a copy of the credit card payment receipt to the cardholder. At this point, the card swiping procedure on the POS machine is completed.

RFID machine taps the card

Tapping the card on the RFID machine is a new type of credit card usage method, and it is also a networking method. When tapping a card, the operator should first check the credit card's validity period and cardholder's last name and other information. Then, select the corresponding card machine according to the card issuing bank and the currency type to be paid, enter the corresponding amount, and place the credit card flatly no more than 10cm above the sensor. The RFID machine will emit a signal after sensing the credit card, and then continue the operation process. After the remote payment gateway accepts the information, the printer (if connected) will print out a receipt for payment by tapping the card, but unlike the previous method, the cardholder does not need to sign. Faster and more convenient than ever. At this point, the card sensing program on the RFID machine is completed.

Manual order pressing

Manual order pressing is usually used when there is no POS machine or the Internet is not available. The order pressing operation must have a pressure-sensitive copy of the "direct purchase order" (at least two copies) and a telephone number. The inspection work before pressing the order is the same as that of POS machine. The operator then prints the card number, name, etc. raised on the credit card onto the purchase form using a credit card pressing device, and writes the amount, date and other information, and then calls the acquiring bank's authorization hotline to report the card information and apply for authorization. , and write the authorization code obtained on the purchase form, and then the cardholder signs it after confirming it is correct. After the operator checks the signature, he hands the credit card and purchase order copy to the cardholder. At this point, the manual order pressing process is completed. Authorization calls are usually made immediately. In some areas with poor communication or good credit ethics, merchants may encounter situations where the merchant will deliver the goods to complete the transaction after pressing the customer's signature. The authorization will be completed in the future, but merchants are at risk of encountering credit card fraud (if a customer uses an invalid card to pay, it will not be discovered immediately if they do not apply for an authorization code immediately).

Online payment

From the perspective of cardholders, online payment is considered to be the riskiest among several credit card payment methods, because people with bad intentions may use Steal user information through phishing, eavesdropping on network information, and fake payment gateways. When paying online, you need to enter the card number, credit card validity period, Visa CVV2 code/MasterCard CVC2 number next to the signature column on the back of the card, online transaction password, sometimes you need to enter your name, verification code randomly generated by the web page, etc. After the input is completed, click Submit to complete the online payment.

TV and telephone transactions

Similar to online payments, card number, validity period, Visa CVV2 code/MasterCard CVC2 and other information are required.

Pre-authorization

Pre-authorization is generally used to pay a deposit, that is, freezing a part of the available credit card limit as a deposit. The process of pre-authorization is similar to that of manual order pressing, but the content of the call requires pre-authorization of the corresponding amount. It does not require payment, and there is no need to press the order. You only need to issue a certificate of receipt of the deposit. Generally, pre-authorization will be canceled by the merchant during checkout. If the merchant forgets to cancel, you can call the merchant to request cancellation. You cannot cancel by calling the authorized agency. Or, wait for the bank to automatically cancel the pre-authorization (usually 7 to 30 days).
