POS(point of sale, also called EPOS in Europe, that is, electronic products at the point of sale) means "point of sale" in Chinese. It is called point-of-sale information management system, which is a terminal reader equipped with barcode or OCR code technology, and has the function of cashing cash or barter exchange. Its main task is to provide data services and management functions for commodity and media transactions, and to carry out non-cash settlement. It is an electronic system widely used in retail, catering, hotels and other industries. Its main function is to count the sales, inventory and customer purchase behavior of goods. Through this system, operators can effectively improve their operating efficiency, which can be said to be an indispensable tool for modern retail industry.
POS is a multifunctional terminal, which can realize automatic transfer of electronic funds by being installed in special merchants and credit card acceptance outlets and connecting with computers. It has the functions of supporting consumption, pre-authorization, balance inquiry and transfer, and is safe, fast and reliable to use. It is difficult to obtain basic business information in bulk transactions, so the introduction of POS system is mainly to solve the blind spot of retail information management. An important part of chain store management information system.

Principle analysis
Basic principle of pos machine
The basic principle of POS system is to first create commodity information in computer files, and through the online structure of computer cash register, directly read the barcode on the commodity through the optical reading device on the cash register (or directly input the code through the keyboard), and immediately display the commodity information (unit price, department and discount), thus speeding up the cash register speed and accuracy. The sales details of each product (price, department, time period and customer level) are automatically recorded and then sent back to the computer by the online architecture. All kinds of sales statistics and analysis information can be generated by computer calculation and processing as the basis of management.
The POS machine reads the magnetic stripe information on the cardholder's bank card through the card reader, the POS machine operator inputs the transaction amount, and the cardholder inputs the personal identification information (i.e. password). POS sends information to the issuing bank system through the UnionPay center, completes online transactions, gives information about success or failure, and prints corresponding bills. The use 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 the tedious labor of manually querying blacklists and pressing bills, and improves work efficiency.
The design requirements of magnetic stripe card module meet the needs of three-track magnetic cards, that is, the module should be able to read magnetic cards with 1/2, 2/3 and 1/2/3 tracks.

Domestic development
develop
Domestic Internet innovative third-party payment enterprises integrate the use of electronic signature with POS card swiping system, and realize the green and environmentally-friendly paperless POS receipt service. Using electronic signature can not only effectively save time, money and paper, but also help to improve service efficiency and customer satisfaction, simplify business processes and improve work efficiency. Using the electronic signature provided by payment, there is no need to upload the receipt, which not only avoids the extra workload, but also avoids the loss of the authenticity of the transaction and the settlement for the merchant caused by the loss of the receipt. There are a series of digital "anti-counterfeiting" behind the electronic signature of payment, which can prevent the cardholder's signature from being stolen or tampered with.
safety performance
On the basis of optimizing and upgrading the POS acquiring control ability of enterprises, the rights and interests of consumers and cardholders such as information security and capital security will be further protected from infringement. At the same time, the use of payment electronic signatures, through close cooperation with integrators, ensures that electronic signatures meet the requirements of the national electronic signature law, thus having absolute legal effect.
equipment component
Pos mechanism
A complete set of POS machines, in addition to hardware, also need a set of collection software. The software includes the functions of entry, sales, statistics, printing and cash box control. In fact, it is a dedicated small database application software.
POS is divided into brand POS and DIYPOS. The price of DIYPOS will be much lower, because the price of peripherals used fluctuates greatly. The recent price of POS is 3000~3500. DIYPOS is different from computer, the chassis is different and the display is different, but the computer can realize POS function. Connecting a computer with a POS peripheral can realize the POS function, but the style is ugly.
POS peripherals include:
Customer display, divided into LED and VFD-for customers to see, display the amount received, and change the amount.
Bill printer-A printer that prints receipts. There are two kinds of printers: stylus printers and thermal printers. The price of stylus printers is relatively high, ranging from 300 to 500 yuan. Don't buy printers below 300 yuan, the failure rate is very high.
Card reader-a device for swiping magnetic cards, which is mainly used for membership points and stored values of members in the store.
Scanning equipment-equipment for scanning commodity bar codes, which can be divided into scanning gun and laser platform according to style. It is recommended to use a scanning gun. Scanning transmitter can be divided into infrared ray and laser, and infrared ray is called CCD.
operational approach
New touch screen pos machine
1. Before using the POS machine, it is necessary to check whether the power supply is connected, whether the printer and the host computer are connected normally, and whether the POS printing paper is installed.
2. At the end of business every day, the operator should perform "day-end treatment". It is especially important to note that when the POS machine needs to be replaced for some reason, it must be turned off and replaced after the "day-end treatment" is completed.
3. Don't charge the cardholder repeatedly because of repeated swiping. During the transaction, if the purchase order is not printed, the operator should first select the "reprint" function; If the voucher cannot be printed after re-printing, he should select the function of "Query Current Transaction" to query the batch number and merchant serial number of the transaction, then turn off the power supply, check whether the printer is connected correctly, and select to print a specific record for processing after re-plugging.
If you still can't print, check the balance on the POS machine, and then check with the UnionPay customer service center whether the transaction has been reversed. If the reply is really successful, you can copy the consumption elements on the POS consumption list, and the cardholder can take away the goods with his signature or cancel the transaction. Don't swipe your card again at will to redo the transaction, otherwise it will deduct the account for the cardholder repeatedly.
4. If you fail to swipe your card during the transaction, you need to press the required transaction code key again to avoid mistaking other transactions for "consumption" and causing repeated deductions.
5. Enter the cardholder's password. In order to ensure the security of transactions, cardholders need to enter the correct bank card password when they trade at public POS machines. If the cardholder's bank card has no reserved password, the operator directly presses the "OK" key of the POS machine to conduct the transaction, and the transaction is successful.
6. Don't forget to ask the cardholder to sign the shopping list. If the cardholder's signature is inconsistent with the reserved name on the back of the card or the letter of the name on the front of the card, you can check with the issuing bank.
7. The transaction type on the printed purchase order should be carefully reviewed to avoid changing "consumption" into "pre-authorization" or "return" into "consumption", resulting in wrong accounts.
8. Return transactions can be returned in whole or in part. If the return is unsuccessful, do not refund the cash or let the cardholder take the goods at will. You can handle it according to the POS prompt, or you can contact the maintenance personnel of UnionPay.
9. Don't just plug in the communication line. The communication interface of POS machine is a special interface (line port), so don't confuse each other.
10. For debit cards and cards of member banks that have not signed a manual card pressing agreement, the card pressing transaction is invalid and the issuing bank will not recognize it. Therefore, do not accept pressing cards.
Cashiers can use the cash register to collect money, return goods, exchange goods, make inquiries, discount and cancel transactions, among which the functions of return goods, exchange goods and discount can be set to be controlled by the manager. The basic operation flow of cashier's daily work can be divided into startup, entering sales, saving spare parts, executing sales, closing accounts, quitting sales and shutting down.
Determined by the sales function of the system, the cashier must enter his password correctly on the computer, and can enter the cashier sales state normally after being confirmed by the system. During the sales process, all the accounts will be automatically recorded under the cashier's account until the sales exit and disembarkation. Payment methods of sales settlement can be divided into RMB, cheque, credit card, gift certificate, etc.
operation sequence/order
Sales operation
Pos machine sales
① Scan and read the barcode information of commodities with a scanner.
At this time, the name, quantity and price of the goods for sale can be seen on the cashier screen, and the price of the goods can also be displayed on the customer display screen.
(2) Other commodities can repeat the above operations. When there is only one similar commodity, it can be scanned directly.
(3) In the process of collection, you can press the Subtotal button to display the subtotal amount of the goods at any time.
(4) When the final sales amount is confirmed, you can press the Total button to settle the collection.
Payment type/method
Payment methods are divided into cash, check and credit card for customers to choose from.
① Cash payment
If the customer's payment is equal to the purchase amount, you can press Enter directly; otherwise, press Enter after entering the paid amount. At this time, the system will automatically print the bill, open the cash drawer and display the amount of money that should be given to the customer. After the cashier receives the money, changes the money and closes the cashier drawer, the screen will automatically return to the sales state, and the sales process is over.
② Check payment
When paying by check, the system will ask for the check number. After entering the check number, the system also needs backup. Put the back of the check on the plane of the printer, press Enter, and the system will automatically print the backup book and bill. Open the cash drawer and the cashier puts the check in the cash drawer. After closing the cash drawer, the screen returns to the sales status and the sales process ends.
③ Credit card
When using credit card for payment and settlement, if the mall and the bank do not realize real-time transfer, the system will continue to ask about the type of credit card within the limit allowed by the bank or after authorization. Press Enter after selection, and the system will continue to ask for the card number. Brush the card number in the magnetic card reader of the cash register, and the screen will return to the sales status. The sales process is over, and the next step is to go through the formalities of pressing cards and signing.
Cashiers have to check out before they leave work every day. Input the cash, check amount and credit card amount in the cash drawer into the cash register, and the cash register will record the cashier's work at this stage and print out the cashier's sales report, reflecting the profit and loss of income, so as to carry out handover, handover, payment and settlement.
In the past, the conventional cash register in the retail industry could only handle simple sales operations such as cashier, invoice and checkout. The management information obtained is extremely limited, limited to the basic statistics of total sales and departmental sales.
For general retail stores, there are no basic business information such as gross profit analysis, single product sales data, unsalable goods, commodity inventory and turnover rate of tens of thousands of commodities. The introduction of POS system is mainly to solve the blind spot of retail management mentioned above.
POS system can not only provide accurate sales information, but also grasp the inventory of all goods in the store through sales records for reference by purchasing departments or link with EOS system.
POS settlement
Settlement through POS system should go through the following steps:
Pos machine settlement
(1) The barter cashier system of the local barter agent or special customer inputs the purchase or consumption amount of the buyer member into the POS terminal.
(2) The card reader (POS machine) reads the authentication data of the magnetic stripe on the advertising barter card and the member number (password) of the buyer.
(3) The settlement system sends the input data to the central supervision account.
(4) After the settlement data processed by the advertising barter cashier system is confirmed, it shall be signed by the buyer's member. The buying and selling member and the barter agent or special merchant each keep a receipt stub, and the barter agent or special merchant will mail the receipt stub to the barter company.
(5) After the barter company confirms that the buyer has received the goods or media services, the settlement center will allocate the barter quota. Complete the settlement process.

Decoding technology
Server decoding
It is to connect a dialer in front of the pos machine to change the telephone line number, so that you can see the number of your registered POS machine after the data is sent to UnionPay or the banking system, so that you can use a fixed POS in other places or anywhere, and then send the information to the bank through transparent transmission. Generally speaking, the server is simple to set up and mainly uses its transparent transmission technology to modify the phone number.
Pos decoder
It is a palm-sized box, which can be used for decoding of all fixed pos machines. You need to have a fixed telephone line in the POS machine, one tied to the bank and the other unbound, and then add a dialer to transfer money. Your machine can be used all over the country. Because the cost of this equipment is not high, the cost of decoding is relatively low. Because it is fixed-line transmission, the signal loss is small, and secondly, there is no risk because there is a binding number to send data to the bank. Generally speaking, the price is average and the signal is stable. It is used more at this stage.
Background decoding
That is, you need to go into the background of the machine and change the parameters. This method first requires that the machine itself has a background channel, and then you need to get the password and password for inputting background parameters. But some machines can't be changed even if they enter the background, so they have to decode in other ways.
The simplest method, but it is very difficult for the decoder to have no real skills. The disadvantage of this decoding is that the parameters of POS machine need to be changed. You can simply think about the harm of changing the parameters of POS machines.
Psam and sam cards
The bank put a key setting in the machine, which contains all the parameters of the system. The new machine has this setting. There is no way to decode this without professional knowledge and professional equipment. Generally, only people in the bank can decipher it.
In short, the parameters of the POS machine itself must not be changed, otherwise it is equivalent to picking up sesame seeds and losing watermelon. Secondly, the control after decoding should be in your own hands. If others can turn off your decoding at any time, and more importantly, if you can read your signal and meet malicious elements, the loss will be disastrous. If the banking system is upgraded or something, your POS will be finished. More importantly, you can't give the POS to others easily, otherwise the consequences will be unimaginable.
Cost adjustment
According to the notice of the National Development and Reform Commission, the bank card processing fee was officially adjusted from June 9, 20 16. For the restaurant with the highest original rate, the handling fee was reduced from 2% to 1.25%.
According to the adjusted scheme, the overall rate of card swiping is reduced by 53% to 63%.
According to the new standard, from 2065438+June 9, 2006, the catering rate decreased from the original 1.25% to 0.6%.
The charge for swiping cards in department stores decreased from 0.78% to 0.6%, and that in supermarkets decreased from 0.5% to 0.38%.
The public welfare category is still 0%.
Real estate and cars used to be 10 yuan. Now, with reference to the catering and entertainment charging standards, the single rate is raised.
Vulnerability event
Pre-authorization for cashing in credit cards with POS machines broke out on a large scale, and banks, UnionPay and third-party payment companies triggered pre-authorization risk events. The cash involved is about 2 billion yuan, and the funds of the merchants involved have been frozen. Banks collect relevant cash funds and work together to minimize the possible risk losses caused by the incident. [ 1
