With the rise of unmanned retail, the financing market for new retail is booming. Vending machines have become more and more common in China in recent years, such as in public space subway stations, airports, shopping malls, or even can be seen in our company rest area. But how do vending machines work?
New saier is developed in cooperation with some well-known brands companies, such as ICT and ITL, which can recognize the currencies of more than 200 countries around the world. At present, the machines exported by New Saier are working perfectly in many countries, especially the orange juice vending machine. In Australia and South America, the daily sales volume is as much as 30-50 cups, the investment customers can get back the cost within 3-6 months.
Before introducing new saier vending machine, let us first understand the working principle of the vending machine.
The general principle and process of the work of the vending machine is:
.Insert banknotes or coins, and the currency recognizer performs recognition.
.Select goods, press the button of goods selection, the vending machine program will add or subtract cash based on the price of the goods.
.In process, if the amount inserted is insufficient, there will be a prompt, if the amount is sufficient, it will be in process directly.
.Waiting for the customer’s further operation, if you choose to change without buying other things, the vending machine will automatically change coins according to the calculation result just now, and the shopping is complete.
After the goods are selected, the vending machine program will initiate a payment application QR code (WeChat, Alipay or other electronic payment) to the terminal server, and the QR code will be directly displayed on the vending machine display.
After the customer scans the code, the terminal server will check whether the payment account has received the payment. If it is received, the terminal server will issue a shipment instruction to the vending machine, and the vending machine will ship the goods according to the instruction.
Smart vending machines have many functions and their principles are complex. Some do not require payment and can be shipped according to the entered delivery code. The principle is that the customer enters the delivery code or lottery code, and the vending machine sends the delivery code to the terminal server, and the terminal server picks up the goods. The code is verified, and the corresponding shipping instruction is sent to the vending machine, and the vending machine outputs the corresponding product according to the instruction.
However, QR code payment is not popular in foreign countries. At present, except China, other countries still use banknotes or coins for purchase. Most of the European countries and American countries are more accustomed to using credit cards.
So how does the vending machine identify the authenticity of the coin?
The identification of coin denomination and authenticity is a very complicated process. The coin identification module in the vending machine is a very accurate instrument, which is mainly composed of a circuit board, a coin chute and a coin sorter.
When you put a coin in the vending machine, the coin will first pass through two sets of light sensors, which can measure the diameter of the coin.
The light sensor consists of an LED light emitting device and a light receiving sensor. The green part represents the LED light-emitting diode, the light it emits will be received by the opposite light receiving sensor. When the coin passes between the two, the light is blocked, and the sensor generates a corresponding signal.
When the coin passes the sensor, the light will be blocked. The control circuit board will calculate the time when the coin blocks the light and the time difference between the two sets of sensors, and then the diameter of the coin can be measured. The diameter of a dollar coin is larger than that of a fifty cent coin, and it takes longer to block the light of the sensor. Not only that, the light sensor can also accurately measure the diameter of the coin to determine whether it is a circulating coin, which is the first step in distinguishing the authenticity.
The real coin adopts the nickel-plated steel core process, which has its special electromagnetic characteristics. The specially designed high-frequency oscillation circuit can effectively distinguish the electromagnetic impedance of the metal material and further screen the authenticity. Specifically, the coin will pass through an electromagnet composed of two copper coils, whose function is to detect the metal composition and electromagnetic spectrum characteristics of the coin.
Metal cutting magnetic lines of force will induce current, and the current will generate a magnetic field. According to the principle of magnet electric mutual conversion, when the copper coil has current, it will become an electromagnet, forming a fixed magnetic field. When the coin passes by, the magnetic field will be cut and the copper will be changed The magnitude of the current in the coil.
In addition, different metal components have different effects on the magnetic field in the copper coil. The single-chip microcomputer can determine the coins corresponding to different metal components according to the change of the induced current in the copper coil.
As long as the coin passes through the above two identification devices, the vending machine can sense the denomination of the coin in less than one second, and then guide them to the corresponding coin slot to realize sorting and storage according to the denomination.
Of course, there is a very low probability that the recognition device will not recognize the real currency or accurately recognize the counterfeit currency, then it will re-enter the refund port. This is why we sometimes put in coins and then back out. If it’s real coins, just reinvest it, but if it’s counterfeit coins, don’t waste energy. Counterfeit currency vending machines won’t accept them.
After the machine recognizes and counts the amount, it will automatically ship. If you need to change, the coin storage slot will slowly release the coins one by one according to the corresponding amount. Therefore, the sound of change coins is the sound of “puff” and “puff” at intervals, rather than “crash” falling together.
Now, we will take a look at New Saier’s orange juice vending machine that are exported to Europe countries. How they customize different payment method according to customer requirements.

If base on the paper money payment mode, how does the vending machine identify the authenticity of the paper money?
Irradiating the fluorescent characters on the renminbi with a certain wavelength of infrared laser will cause the fluorescent characters to produce a certain wavelength of laser light. Through the detection of this laser, the authenticity of the banknote can be distinguished. Due to the difficulty of imitation, it is very accurate to identify fakes.
Some parts of the large-denomination real banknotes (20 yuan, 50 yuan, 100 yuan) are printed with magnetic ink, and the magnetism of the banknote is detected by a set of magnetic heads, and the magnetism of the circuit is analyzed to distinguish the authenticity of the banknote. In the magnetic detection, the magnetic head and the banknote are required to rub well. If the head is too high, the impact signal will be large, causing false alarms; if the head is too low, the signal will be weak, causing false alarms. The detection needs can be met by controlling the height of the magnetic head (guaranteed by processing and assembly) and installing a banknote pressing rubber wheel above the magnetic head.
Infrared penetration detection
The working principle of infrared penetration is to use RMB paper which is stronger and denser and the ink thickness printed with gravure printing technology is higher, so the infrared signal absorption ability is stronger to distinguish the authenticity of banknotes. There is a certain difference between the paper characteristics of RMB and counterfeit banknotes. When infrared signals are used for penetration detection of banknotes, their absorption capacity for infrared signals will be different. Using this principle, it is possible to realize counterfeit identification. It should be noted that the color and thickness of the ink will also cause differences in infrared penetration. Therefore, it is necessary to perform mathematical operations and comparative analysis on the signals of infrared penetration detection.
The working principle of fluorescence detection is to detect the paper quality of the renminbi. The renminbi is made of special paper (containing more than 85% of high-quality cotton), and counterfeit banknotes are usually made of plain paper that has been bleached. The bleached paper will have a fluorescence reaction (blue light with a wavelength of 420-460 nm is diffracted under the excitation of ultraviolet rays) under ultraviolet light (blue light with a wavelength of 365 nm), but there is no fluorescence reaction on real banknotes. Therefore, by irradiating the banknote with an ultraviolet light source and simultaneously detecting the fluorescence reflection of the banknote with a silicon photocell, the authenticity of the banknote can be judged. In fluorescence detection, you need to pay attention to the shading of the detection space, otherwise outside light entering the detection space will cause false alarms. In order to eliminate the interference of ambient light on the identification of counterfeit, a set of color filters with the same transmission wavelength as the fluorescence reaction wavelength of the counterfeit banknotes must be installed on the surface of the silicon photocell.
Then let’s take a look at this orange juice vending machine of new saier, which is exported to Australia, which denominations of banknotes can be recognized.

The development of vending machines towards electronic payment is a major trend. Perhaps coin-operated payments will be completely eliminated in the near future, because the new face-based payment is so advantageous that you can buy things without a mobile phone. As a powerful vending machine manufacturer in the industry, Changzhou New Saier has developed various unmanned self-service devices that can support cash, mobile phone code scanning and face payment!
