1. Project background
In recent years, the upgrading of consumer demand in my country and the emphasis of merchants on customer privacy and consumer experience in the consumption process have caused traditional short-range identification methods such as M1 cards to be criticized. Especially in some star-rated hotels, membership clubs, brand stores, amusement parks and other places, these consumer places receive VIP guests, hoping to be as fast, comfortable and humane as possible when access is prohibited and services are provided.
At the same time, security considerations are also indispensable. Most dignitaries need a relatively secret consumption space and do not like popular amusement methods. Therefore, the personnel access control systems in these consumer places often need to take into account the needs of these two aspects.
2. VIP customer management application program
Radio Frequency Identification TechnologyRFIDIt is a non-contact automatic identification technology, which automatically recognizes the target object and obtains related data through radio frequency signals. The identification work does not require manual intervention. It can work in a variety of harsh environments. The distance between reading and writing tags is up to several meters to hundreds of meters. , Can be used in access control, attendance, warehousing, logistics, clothing and other fields.
From the perspective of speed and comfort, the access control of gate personnel in such consumer places is basically medium-distance (about 1.2 meters) electronic tags (mainly passive tags) are more suitable. Passive tags for high-speed communication are not only very suitable for reading and writing operations. Ideally, multiple tags can be read at the same time, no need to wait in line, and no need for VIPs to approach the card reader, thus creating a fast and comfortable consumption atmosphere. On the other hand, from a security point of view, the consumption of these VIP venues has generally been fully electronic, and it is impossible to pay cash in all consumption links. Supermarkets do not want VIPs to have the idea of consuming a considerable amount of money on shopping. Want to use an efficient way to record the consumption location, habits and amount of VIPs, establish the customer’s consumption profile, provide guidance plans for subsequent customer services, and easily achieve customer incentive goals such as cumulative discounts on consumption and lottery draws.At this time, the electronic VIP card is more suitable to use short-distance passive tags: the mature low-frequency tag security performance has been
It provides a solid technical foundation for the security of the payment process. As a result, an “electronic label” membership card developed by Suzhou Xinhui IOT Technology Co., Ltd. to better serve customers came into being. One card can fully satisfy the two applications and is sold exclusively for supermarkets and brand chains. The store provides a brand-new customer management method.
The most basic RFID system consists of three parts:
1) Electronic tags (Tag): Composed of coupling elements and chips, each tag has a unique electronic code (UID), attached to the object to identify the target object; when illuminated by radio frequency signals, it can reflect back and carry a digital code The radio frequency signal of the information is processed and identified by the reader, and can be reused, and the number of repeated erasing and writing is up to 100,000 times.
2) Reader: Sometimes called an interrogator, a reader or a readout device, it is used to generate and transmit radio frequency signals and receive the radio frequency signals reflected by the electronic tag, and obtain the tag after processing Data information, and sometimes a device that can write label information, can be designed as a handheld or fixed type;
3) Antenna: Transmit radio frequency signals between the tag and the reader. Can be set to built-in or external.
The system uses RFID card issuers to authorize customer membership according to the characteristics of the consumption patterns of well-known brand members. From the moment the customer enters the store, the RFID detection system at the door will identify the member’s identity and level, including personal consumption habits, personal preferences, and past consumption records. After waiting for information, the clerk immediately provided targeted shopping guides to cater to the psychology of customers, make VIP customers more distinguished, change the past simple discount membership management methods, improve service quality, and fundamentally achieve the purpose of promoting sales. The system automatically analyzes customer consumption habits and grasps potential needs based on the consumption records and fitting conditions of member customers, which not only consolidates the relationship between member customers, but also provides an accurate basis for market decision-making.
Three, VIP member customer management
When a VIP enters a supermarket or specialty store within 1 meter, the system can automatically search for the person based on the unique number of the passive tag carried with him, and display the person’s related information and welcome message on the wall of the supermarket. At the same time Display customer information (such as name, preferences, points status, past purchase records, etc.) on the front desk service computer and prompt relevant service personnel to prepare for service in advance.
VIPs need to save personal valuables after entering the supermarket or specialty store, and the security of high-frequency tags can be used to realize the electronic management of valuables storage cabinets. In subsequent consumption activities, the dual-frequency card can be used as an e-wallet for transfer records, and can be used for discounts, gifts, and consumption points reward activities according to the prior agreement. The electronic tag has large capacity, reasonable partition and high security level, which is very suitable for all aspects of electronic wallet requirements.
In some large supermarkets, VIPs generally do not carry their mobile phones during consumption, and friends who are familiar with them all look for them through the supermarket service desk. At this time, the microwave active card can play the role of personnel positioning. The long-distance readers placed at some aisles and entrances can feed back all the VIPs passing by to the back-end system one by one, so that the person can be quickly located when needed. If the VIP does not want to be disturbed in any way, he can also ask the supermarket to filter all his whereabouts records in advance.
Mobile long-distance readers can play an important role in quickly providing instant consumer demand for VIPs. The mobile reader (PDA) is carried by the waiter and listens to the consumption needs of the VIPs at any time. It can record the VIP’s demand list on the spot and send it to the backend in real time. After the backend gets the list, you can immediately prepare related matters. This service is fast, accurate, not prone to errors and delays.
As a leading domestic supplier of RFID products and solutions, Suzhou Xinhui IoT Technology Co., Ltd. completed the VIP membership identification system project of a large shopping mall in Wuxi in June 2012. This system uses advanced radio frequency RFID technology to manage member identification, personnel flow management, regional statistics and positioning, and track data mining to achieve precise management of customer service.
In response to customer management needs, Xinhui IoT installed a total of 82 UHF RFID readers and 328 antennas for the 10-story building of the mall, which are used to collect data on VIP personnel cards, and realize regional positioning and positioning according to certain algorithms. Track management.
As we all know, UHF RFID tags are very sensitive to human bodies, metals and other substances, and the reading distance and accuracy will be greatly affected. This project integrates label design technology, reader antenna design, reading control and other technologies, and realizes that when the VIP card is placed in the wallet and the wallet is placed arbitrarily, the reading rate of the card can reach more than 95%, and the reading distance More than 3 meters. So far, 100,000 VIP membership cards have been issued. At the same time, the RFID middleware software independently developed by Xinhui IoT and with independent intellectual property rights is used in the project, which very well realizes the coordination of multiple RFID readers in dense environments, and solves the multi-reading encountered in the implementation of large-scale RFID systems. The problem of mutual interference between writers; at the same time, the middleware has functions such as equipment online management and massive data management.
