What is a POS terminal machine?

POS (Point of sales) means “point of sales”, the full name is point of sale information management system, is a terminal reader equipped with barcode or OCR code technology, with cash or barter line cashier function.

It can be installed in the designated merchants and acceptance outlets of the credit card to connect to the computer to form a network to realize the automatic transfer of electronic funds. It has the functions of supporting consumption, pre-authorization, balance inquiry and transfer, etc. It is safe, fast and reliable. It is difficult to obtain basic operating information in large transactions, and the introduction of POS systems is mainly to solve the blind spots of information management in the retail industry. An important part of the chain store management information system.

How does the POS terminal machine work?

The basic principle of the POS system is to first create the product information in a computer file. Through the computer cash register connection structure, the barcode on the product can be directly read through the optical reading device on the cash register device (or directly input the code from the keyboard) immediately Can display product information (unit price, department, discount…) to speed up the speed and accuracy of the cash register. Each product sales detail data (sale price, department, time period, customer level) is automatically recorded, and then sent back to the computer by the online structure. Various sales statistical analysis information can be generated through computer calculation and processing as the basis for operation and management.

The POS terminal machine reads the cardholder’s magnetic stripe information on the bank card through a card reader. The POS operator enters the transaction amount and the cardholder enters personal identification information (ie password). The POS sends the information through the UnionPay center. The card-issuing bank system completes online transactions, gives information about success or failure, and prints the corresponding bills. The application of POS realizes online consumption of bank cards such as credit cards and debit cards, ensures the safety, speed and accuracy of transactions, avoids the cumbersome labor of manually querying blacklists and pressing orders, and improves work efficiency.

The POS terminal machine reads the user information in the magnetic stripe and sends a deduction request to the payment management system platform (UnionPay) in a wired or wireless manner, and finally returns the processing result after the UnionPay platform completes the information confirmation check. The emergence of POS machines has greatly changed people’s payment habits. In particular, mobile POS machines that use wireless communication technologies such as GPRS modules have further improved the convenience of payment.

The design requirements of the magnetic stripe card module meet the needs of three-track magnetic cards, that is, this module must be able to read 1/2, 2/3, 1/2/3 magnetic cards. The communication interface circuit is usually composed of interface circuits such as RS232 interface, PINPAD interface, IRDA interface and RS485. The RS232 interface is usually the POS program download port, the PINPAD interface is usually the interface between the host and the password keyboard, and the IRDA interface is usually the infrared communication interface of the mobile phone and the landline. Interface signals are usually composed of a sending signal, a receiving signal and a power signal.

MODEM board is composed of central processing module, memory module, MODEM module and telephone line interface. First, the POS will first detect the /RING and /PHONE signals to determine whether the voltage on the telephone line can be used. The switch returns a dialing tone, the POS dials, the sending light flashes, and the dialing starts. The communication protocol determines the switch and After the signal handshake confirmation between POS, the data exchange of POS starts, and the signal is sent and received through the MODEM circuit; after completion, hang up and end the process.
