1. Industry background
In the clothing industry, there is the problem of inventory at the exclusive counters of specialty stores. As the clothing industry, because the products sold every day are branded clothing with relatively high value, the daily inventory of goods is very important, and the inventory of goods , Can understand the sales situation of various types of products in time, help to complete the company’s digital analysis of the market acceptance of various products, and can also check the number of clothing to reduce product loss, management errors and other issues. However, the current clothing inventory work is basically done manually, and the actual situation of clothing products is mixed in variety and large in quantity. A large number of products are counted by a small number of sales personnel, which results in a huge amount of time-consuming inventory work. Data shows that it takes an average of five hours for an ordinary specialty store to take an inventory of the products in the store. The problem of inventory efficiency has led to the inability of each specialty store to inventory products daily or weekly. At the same time, the flow of people in the store is very large, and the quality of internal staff and other human reasons have caused clothing thefts to occur frequently. In response to the above problems, Beijing Tianyi Zhonghe Company has launched a set of management technology based on RFID technology to inventory and other clothing. solution. Today, with the rapid development and application of RFID technology, RFID electronic and information management of clothing is an important means to strengthen inventory management, sales management, and improve management efficiency. The electronic and informatization of clothing management will greatly improve the efficiency of the storefront (inventory, inventory, and storage), reduce the rate of theft, and increase the turnover rate of funds.
2. Scheme principle
The electronic tag is made into the form of a clothing tag, and a chip is implanted in the clothing tag. This chip has a unique 64-digit ID code in the world. There is also an integrated circuit in the tag to establish a unique ID code and information in the tag. The corresponding relationship. Each tag has a corresponding display. The connection between the electronic tag and the clothing is designed as a return circuit, and it will alarm as long as it is cut short or is forcibly removed.
At the same time, the use of RFID technology for clothing identification will also improve inspection efficiency and realize the collaboration, transparency and visualization of supply chain management through RFID. According to our company’s understanding, this new technology is still new in China. We use this advanced technology to automate the management of inventory, transportation, and sales processes in the apparel industry.
The RFID electronic clothing tag is embedded with a smart “core”, which is connected to the back-end computer through the data reading of the electronic tag. The computer binds each ID code to some clothing parameters, so that when a certain When an ID is coded, the corresponding clothing and related information of the clothing will be displayed on the computer. Secondly, the clothing tag can be verified by a handheld reader, which is extremely efficient, with a reading and writing rate of 0.3 seconds per time, and completely solves the multi-purpose phenomenon of one card. In addition, the clothing tag system is all computers connected to the Internet, which effectively solves the problems of statistics, heavy workload, and high error rate.
2.1 Features and advantages of RFID smart electronic tags
The variety of RFID products continues to be enriched. At present, the prospect of active electronic tags in the clothing industry is great, the cost of electronic tags is continuously reduced, and the scale of applications is rapidly expanding. Compared with other automatic identification technology products, RFID has the following advantages:
1 Safe and free: 2.4Ghz global open microwave frequency band, no need to apply and pay. Low power consumption, long service life, low average cost, safer, healthier, and no radiation damage.
2 Fast reading and writing speed: using non-contact mode, no directionality requirements, once the tag enters the magnetic field, the reader can read the information in it instantly, usually within a few milliseconds to complete a read and write. The anti-collision mechanism adopted enables it to process multiple tags at the same time to realize batch recognition. The maximum simultaneous recognition can reach so many per second, and it can be recognized in motion.
3 High data security: RFID is a unique identification internal code that is fixed in the chip before leaving the factory in accordance with the internationally unified electronic product code encoding system and does not repeat 4o bits. It cannot be copied or changed. This technology is difficult to be counterfeited or invaded, and it is safer to use domestic chips.
4 Superior physical performance: It can store permanent data and non-permanent data. The information in the rewritable memory can be changed freely. The data can be dynamically updated, used repeatedly (erased and written 10,000 times, read unlimited), has a long service life (10 years or 100,000 reads and writes), resistant to high and low temperatures, and can adapt to various working environments and working conditions, especially suitable for oil pollution , Dust, radiation and other harsh environments.
5 Convenient reading and writing: Data reading does not require a light source, and can even be carried out through the outer packaging. When the active tag with its own battery is used, the effective identification distance can reach more than 100m.
6 Anti-collision: There is a fast anti-collision mechanism in the electronic tag, which can prevent data interference between cards. Therefore, the reader can “simultaneously” process multiple non-contact radio frequency cards, which can process more than 200 at a time, without a light source, and can even read data through external materials.
Major shopping malls and brand stores use RFID to realize the coordination, transparency and visualization of supply chain management, and use electronic tags to realize the automation of anti-theft economic management.
2.2 Problems that can be solved by the automation of electronic label store management
1. For specialty stores with high passenger flow, expensive clothing, and low-quality staff, it can effectively solve the problem of clothing being stolen and stolen.
2. Multi-specialty store collaboration: For the needs of circulation, the products of clothing industry companies are often distributed in different warehouses, so that they can be transferred, distributed, and replenished. The inventory of each warehouse needs to be monitored every day to ensure Timely supply. Through warehouse management automation, the inventory of each warehouse can be checked at any time, so that the logistics process of products can be tracked in time.
3. Receipt, delivery, and inventory operations in specialty stores: The most important task in management is to ensure that the booked quantity is consistent with the actual quantity. The use of electronic tags can easily achieve the accuracy of the goods receipt record and the delivery and distribution of goods. The automation of the inventory, so that there will be no omissions or loss of inventory.
4. First-in, first-out: Each product has its use period. Due to the many types of products, it is difficult to ensure that the products are accurately first-in-first-out through manual records and custodian records in actual management. Through the single tracking technology, a clock can be built in for each product, and the intact state of each product can also be recorded, so that the goods can be shipped out of the warehouse within the specified time limit.
5. Out-of-stock alarm: When a certain product is short in the store, it can not only automatically alert the alarm, but also subdivide into details of product composition such as model type, color, and size. That is: if a certain size of a certain style is broken, the staff can be immediately reminded to replenish the goods in time.
6. Statistics of unsalable products: The backlog of products in the clothing industry is a very headache. Through statistics of unsalable products, the residence time of each product (subdivided into models, colors, and sizes) can be obtained, and which products can be quickly discovered Slow sales and out-of-season can easily provide price reduction decisions or exchanges to accelerate product sales and capital turnover.
2.3 Use electronic tags to realize sales automation
Clothing products are a kind of fashion products. Many factors such as the season of sale, the location of the sale, the taste of consumers, the fashion trend, the price of the product, and many other factors will affect the sales of the product. Therefore, real-time tracking of sales status is a very important management content for apparel companies. Problems that electronic label sales automation can solve.
1. Sales statistics: The statistics of daily sales reports are very important to the sales department of an enterprise. It requires accurate results as quickly as possible. Sales statistics include: statistics by style, color, location, size, etc., which can help the sales department allocate and replenish goods in time.
2. Counter sales automation: The use of electronic tags can realize the functions of the portable POS machine in the monopoly counter, and can complete the sales, return, counter inventory, inventory, collection and other sales automation functions; at the same time, it can generate various statistical reports on the day , And send it to the headquarters or local office for sales analysis.
3. Analysis of broken code sales: different products sell well in different locations, and the demand for different sizes will not be the same. It is necessary to replenish goods in time when the code is broken. Sales statistics and analysis can be used to increase the possibility of code breaks that are expected to occur so that timely replenishment can be notified.
4. Allocation between counters: Sales conditions are different between different locations. Allocation between different counters can speed up the circulation of products and maximize the number of sales. Some varieties are not easy to sell on certain counters, but if you change a location (or a counter), it will become a good selling variety. This can effectively reduce the number of unsalable varieties on the counter.
5. Return control: In the market competition, each specialty store is improving the quality of service, allowing customers to return goods. Through statistical analysis of returned goods, product quality problems can be accurately identified, and the responsible department, responsible unit and responsible person can be held accountable.
6. Counter inventory and finding goods: Counter inventory and finding goods is a very tedious and error-prone task for each specialty counter. The use of handheld readers or data collectors can easily achieve counter inventory and find goods, improve work efficiency, and will not cause any inventory errors (especially after using a single unique encoding method), and the inventory results can be quickly sent to the superior unit.
7. Shopping mall reconciliation: Generally, the goods sold in the specialty counters are collected by the mall uniformly, so reconciling and collecting money with the mall is a headache for corporate accountants every month. Using the sales automation system, the daily sales records in the data collector are automatically corresponded to the various accounts of the shopping mall, so that the reconciliation work is clear at a glance.
8. Dynamic statistics of best-selling products and favored products: According to the degree of attention and favorability of a certain product by all customers, real-time tracking is carried out according to the sales status, and mathematical models can be established to analyze consumer preferences to better sell.

3.1 Basic concepts of RFID
RFID is the abbreviation of “Radio Frequency Identification” in English. In Chinese, it is called radio frequency identification, inductive electronic chip or proximity card, proximity card, non-contact card… etc. It is a kind of non-contact automatic identification technology. RFID technology is a non-contact automatic identification technology. Its basic principle is to use radio frequency signals and their spatial coupling and transmission characteristics to realize automatic machine identification of stationary or moving objects to be identified.
3.2 RFID working principle and system composition
RFID working principle: After the electronic tag enters the magnetic field, it receives the radio frequency signal from the reader, and uses the energy obtained by the induced current to send the product information stored in the chip (passive tag or passive tag), or actively send a certain frequency Signal (active tag or active tag); after the reader reads and decodes the information, it is sent to the central information system for relevant data processing.
RFID system hardware mainly includes two parts: electronic tag and reader.
(1) Electronic label
The electronic tag is the real data carrier of the radio frequency identification system. In general, an electronic tag is composed of a tag antenna and a dedicated chip for the tag. According to the different power supply modes of electronic tags, electronic tags can be divided into active tags and passive tags. The active electronic tag contains a battery, and the passive radio frequency tag does not have a built-in battery.
(2) Reader
A typical reader includes a high-frequency module (transmitter and receiver), control unit and reader antenna. In addition, many readers have additional interfaces (RS232, RS485, Ethernet interface, etc.) to transmit the acquired data to the application system or receive commands from the application system.
