One: POS card swiping
(1) The POS machine reads the magnetic stripe information on the cardholder's bank card through the card reader, the operator of the POS machine inputs the transaction amount, the cardholder inputs the personal identification information (i.e. password), and the POS machine sends the information to the issuing bank's banking system through the UnionPay center to complete the online transaction, give the information of success or failure, and print the corresponding bill.
(2) The application of POS realizes the online consumption of bank cards such as credit cards and debit cards, ensures the safety, rapidity and accuracy of transactions, avoids tedious labor such as manual blacklist inquiry and bill pressing, and improves work efficiency.
Two: RFID camera card
(1) Using a card on an RFID machine is a new credit card usage mode and also a networking mode. When picking up the card, the operator must first check the validity period of the credit card and the cardholder's last name. Then, according to the issuing bank and the currency to be paid, select the corresponding punching machine and enter the corresponding amount. The credit card should be placed flat at the top of the sensor no more than10cm.
(2) After the RFID machine senses the credit card, it will send out a signal sound, and then continue to run the program. After the remote payment gateway receives the information, the printer (if connected) will print a receipt for credit card payment, but unlike the previous method, the cardholder does not need to sign, which is faster and more convenient than the previous method. At this point, the card swiping induction program on the RFID machine is completed.
Three: Manual pressure plate
Manual sheet pressing means that according to the bank card acceptance agreement signed between the acquiring institution and the merchant, the cashier uses the stamping machine to complete the normal consumption transaction through manual sheet pressing. This method is suitable for credit cards (including credit cards and quasi-credit cards), and debit cards do not have this function.
