How is “unmanned supermarket” working and safe?

With the continuous development of technology, the concept of “no one” has been applied more and more in various industries. From the purchase to the payment, the customer-only supermarket (referred to as the unmanned supermarket), which is completed by the customer alone, is one of them. In 2018, this form of shopping has landed in many cities. It is reported that there are nearly one hundred unattended convenience stores that are currently undergoing technical tests nationwide.

Unmanned supermarkets can be said to have emerged as the times require. On the one hand, rising labor costs and outrageous rents have made convenience store profits a big problem. Especially in convenience stores in the business district, profitability is even more difficult. On the other hand, the iterative Internet of Things, face recognition, and mobile payment technologies provide technical support for unattended convenience stores, which coincides with the new retail emphasis technology. It is undeniable that the unmanned supermarket has the advantage of being favored by the capital. The intuitive feeling is that the labor cost and the rental cost have fallen sharply. No matter how the retail format changes, improving operational efficiency is an eternal goal. Unmanned supermarkets can save manpower and reduce rental costs.

Before entering the store, the user needs to scan the QR code through Taobao or Alipay to obtain an identity code for entering the unmanned store. After passing through the gate, you can see that there is a camera on the top of the store. The area is divided into daily merchandise purchase area, dining area and rest area. In the daily merchandise purchase area, users are free to purchase goods. Subsequently, the user passes through the shopping channel, and when exiting the channel, Alipay automatically deducts the transaction amount from the bank card.

Before entering the payment channel, the sensor on the door will automatically identify you (mainly linking the user's Taobao and Alipay information). In the channel, the user does not need to display the product deliberately to the camera, nor scan the product code. Through the sensor and the camera, the system can automatically identify the product, even if the product is put into the bag and stuffed into the trouser pocket. . The only slight discomfort is that after entering the channel, the door will automatically close and the user will stay in the fully enclosed space for about 5 seconds.

In the dining area, users can directly order and checkout through the smart screen in front of the small bar. During the meal, when you walk to the big screen on the left side, you can see your current order status through visual recognition technology. In the rest area, the desktop is a large display. There is a camera on the top of the desktop. When the user sits down, the system will automatically recognize the face and the desktop display will automatically log in to the Taobao account. Subsequently, all the items on the desktop display can be dragged into the Taobao shopping cart. The maximum limit for automatic withholding in unmanned coffee shops is 5,000 yuan per person per day.

The first thing to talk about is RFID technology, which summarizes the technical aspects of shopping in an unmanned supermarket in one sentence, that is, by adding RFID tags (commonly known as electronic tags) to each item, and then using radio frequency sensors, pressure sensors, etc. The signal automatically recognizes the target object and acquires relevant data, performs non-contact automatic identification, and completes the sale of the product.

For the identification of goods, there are currently no more supermarkets using RFID tags. RFID, called radio frequency identification, is a communication technology that uses radio signals to identify specific targets and read and write related data without having to identify the physical contact between the system and a particular target. Wireless radio is generally microwave and is suitable for short-distance identification communication.

Each item is affixed with an RFID tag to identify and settle the item purchased by the customer in the "Payment Tunnel". RFID is a mature and inexpensive solution, and retail giant Wal-Mart has used similar technologies to improve the efficiency of supply chain management. When the customer leaves the store, the sensor scans the RFID tag and reconfirms the item purchased by the consumer, and automatically settles the amount on the consumer's account. Of course, it also has some problems, it can not identify the special materials such as glass, so there are merchants such as wheat smart convenience store, then use the mobile phone to scan the QR code on the shelf or directly scan the barcode on the product package to complete the mobile payment of the goods. Thereby avoiding the drawbacks of RFID. But at the same time, RFID technology also has problems such as non-uniform standards, high cost, and data collision. If you want to embark on the fast track of the Internet of Things, RFID manufacturers still need to cultivate.

In the dining area and lounge area of ​​unmanned convenience stores, image recognition technology is applied. There is no doubt that image recognition technology can be said to be the strength of security companies. In this convenience store, the application of image recognition technology is actually relatively basic, only applied to face recognition technology, and only as an access port, the actual participation feeling is too low.

No matter what kind of unmanned retail solution, you must first solve the C-side user experience problem, and then reduce the labor cost for the B-end customer. Because entering the store does not depend on the consumer, no consumer is empty talk. The future of unmanned goods should remove all media, consumers only need to rely on themselves to complete the shopping. Even if consumers walk into the store naked, they can successfully buy goods. To do this, we must first address the identity issue. Face recognition, fingerprint recognition, iris recognition technology, etc. can be realized. Which kind of identification technology is selected depends on the specific situation, and anyway, it is related to security. In the unmanned convenience store, in addition to accurate identification, we must continue to track consumers and analyze consumer behavior. This can be achieved through image recognition technology. For the analysis of dynamic images, the security industry can be said to be the best, especially Hikvision, Dahua shares and so on. After the user selects the product, he enters the specific settlement area. At this time, it is the turn of the RFID technology to play, calculate the total amount of goods through RFID, and then match the user payment account completed by the biometric technology certification, and easily complete the shopping.

Face recognition is one of the most common technologies in unmanned supermarkets. For example, in the consumption process of AmazonGo (Amazon Unattended Supermarket), consumers use mobile phones to enter the store like a subway card. At the same time, the camera at the entrance will carry people. The face recognition and recognition technology is mainly a face recognition system named AmazonRekogniTIon developed by Amazon. This is an artificial intelligence for deep learning that analyzes photos, details the content of the photos and related objects, and also scans the gender, facial expressions, emotional state, clothing, and even the beard of the characters in the photos. Make judgments.

Internet of Things payment technology and big data analysis are also applied. In terms of shopping settlement, if the wheat intelligent convenience store needs customers to scan the code settlement, the Hangzhou Ali unmanned retail store will go further in this respect. In Hangzhou, this 200-square-meter unmanned retail store can accommodate about 50 people to shop at the same time. After the customer scans the code through the mobile phone, he can purchase it at the store at will. After passing the store, he passes a “payment gate”. After the product is identified, the user is automatically deducted and paid in a few seconds. And this is the embodiment of IoT payment technology.

The payment gate of the Ali unmanned retail store is the practical application of the Internet of Things payment technology. Ants and gold-related personnel told the media that the door-to-door scan is to bind the identity, and the second is to authorize a small amount of deduction. Each unmanned retail store has an authorization and binding behavior before entering the store, in order to turn people into a mobile ID. The authorization of the small amount of deduction is the mystery of the customer to complete the automatic settlement of the goods when paying the door.

Quan Bin, vice president of the Wheat Commune, believes that for businesses like the Wheat Smart Convenience Store, many technologies are hidden in the backstage of real-time monitoring of offline physical stores, and this link is also to complete big data on stores and consumer behavior. An important part of aggregation, processing and analysis.

Unmanned convenience stores are ahead of traditional convenience stores by virtue of their technological advantages, providing space for more competitive product pricing; through technology, not only solves the problem of labor costs, but also fully automated settlement mode can eliminate traditional convenience store queues. Payment link to provide a more convenient shopping environment. In addition, through this series of technical means, the consumer behavior and trajectory of customers entering unmanned supermarkets is also more visible and transparent. The online consumption data is also for retailers in the development of consumer data for consumer data and the management of commodity categories. Provides sufficient basic data.

Face recognition, 360-degree dead angle monitoring, big data collection and analysis of consumer behavior, etc., from the door to the door, all actions can be digitized and captured.

These high-tech means also turned a small unmanned convenience store into a "real-life laboratory" for scientific experiments on consumer behavior.

In summary, enter the store (biometric technology) - purchase (image recognition technology) - settlement (RFID technology, biometric technology), interlocking, and security is inseparable!

In addition to working principle, its anti-theft is also closely related to security. Unmanned supermarkets are mostly small shops. Because these convenience stores usually have a small turnover and a high proportion of labor costs. However, due to the large turnover and the relatively small impact of labor costs, the main pain points of the large supermarkets are the supply chain and procurement system. In addition, the consumer structure of large-scale supermarkets is more complex, including many elderly people, and their acceptance of new technologies for unmanned settlement systems is low. At the same time, in the small-scale scene, the image recognition technology is highly acceptable for the investment of high capital and high technology and its accuracy. Once the area is enlarged, it will face problems such as high cost and low accuracy. Therefore, the most urgent need for unmanned sales systems is small convenience stores, and small stores are just an important market for the security industry. What is more special about unmanned supermarkets is that their operating models are completely dependent on the integrity of consumers. Therefore, the risk is relatively higher, and the demand for security will be higher.

Whether it is an unmanned supermarket, an unmanned convenience store, or other unmanned retail stores and shared retail outlets. Since it is unattended and self-service shopping, the whole process of users entering the store, selecting goods, and leaving the store (checkout) has system support for intelligent solutions.

In general, unmanned stores have three technical solutions and their hardware and software configurations. The first is to use machine vision, biometrics, sensor fusion technology and equipment deployment to solve user identification, product identification and intelligent cash register; the second is to use mature RFID tag identification technology and equipment deployment to solve commodity identification and intelligent cash register; The third is to use a lower cost QR code technology to solve commodity identification and intelligent cashier. Regardless of the overall solution adopted by unmanned stores, the risk of theft is generally solved by deploying smart cameras, smart sensors and other hardware.

Judging from the case of landing operation, unmanned supermarkets are inevitably involved. It has been reported that the only six-day fruit box opened in Shanghai, "has not lost to the quality of the people, but lost to the continuous high temperature", so that the high temperature to "heat dead". Of course, after the addition of air conditioning and sunshade curtains, the “hot” candy box returned again and re-accepted.

Although it was only a case of a fruit box, it was no one to boast of Haikou. Other unmanned supermarkets and unmanned shops did not have similar or related conditions. Unmanned supermarkets like “glass boxes”, even with air conditioning and sunshade curtains, some unresolved pain points still exist, such as temperature and humidity management of air conditioners and sunshade curtains, light and dark of lighting system during normal business hours of 24 hours. Management, no-time air conditioning lighting energy management and security alarms in emergency situations, there are still many problems to be solved.

Conclusion: With the advancement of science and technology, the more accurate and convenient monitoring and recognition payment, combined with the saving of manpower and rental costs, unmanned supermarkets will undoubtedly become a new trend of offline sales in the future. Although there are still many problems in the interior of the building that need to be further resolved at this stage, it is believed that in the near future, no-supermarkets will be promoted to bring people smart and convenient shopping life. Unmanned supermarkets will be promoted to bring people a smart and convenient shopping life.
