1. System overview
Competition in the apparel industry is becoming more and more fierce. To be invincible in the market competition, the apparel industry must continuously improve production efficiency and shorten the capital turnover time. According to market research and analysis, through informatization of the entire clothing industry, production efficiency can be greatly improved and capital turnover time can be shortened. At present, most of the clothing industry is all manual work, without any informationization, which leads to poor feedback of the entire information. When problems occur, they cannot be discovered and dealt with in time, which leads to the situation of idle work in many links. At the same time, the situation of product sales can not be grasped in time, leading to the out-of-stock of the best-selling products and the under-sales products, which also reduces the profit.
RFID technology can be informatized from clothing production, product processing, quality inspection, warehousing, logistics and transportation, distribution, and product sales, providing users with real-time dynamic tracking and query throughout the process; achieving information processing, system operation status, and business operation quality Monitoring and management, while providing real, effective, and timely management and decision support information for managers at all levels, providing support for the rapid development of the business, will be able to solve all problems, from now on comprehensively reduce costs, increase profits and competitiveness.
2. System structure and function
Clothing has the requirements of anti-counterfeiting, anti-theft, logistics distribution management and specialty store or store management. In the production process of clothing, an RFID card issuer is used to write some important attributes of a single piece of clothing into the RFID tag and the tag is attached to the corresponding On clothing, the uniqueness of the label can be used as a clothing anti-counterfeiting identification. The electronic tag attached to the packaging box can be used for distribution and adjustment during the delivery process. At the same time, the customer can take out the clothing abnormally through the RFID reader installed at the door. Wait for the situation to report to the police and prevent theft.

2.1 Clothing anti-counterfeiting function
In the clothing production process, use the UHF card issuing machine to write some important attributes of a single piece of clothing such as: name, grade, article number, model, fabric, lining, washing method, implementation standard, product number, inspector number, etc. Enter the corresponding electronic tag and attach the electronic tag to the garment. The attachment method of the electronic tag can be: implanted in the clothing, made into a nameplate or tag, or adopts a recyclable anti-theft hard tag, etc. Each piece of clothing is given a unique electronic tag identification that is difficult to forge, which can effectively avoid counterfeiting and well solve the problem of clothing anti-counterfeiting.
2.2 Warehouse management
Due to the feature of RFID technology that can identify multiple tags at the same time under non-contact and non-visual conditions, that is, dozens of full boxes of clothing with electronic tags can be accurately read all of their logistics data at one time through an RFID reader , Which greatly improves logistics efficiency. If RFID technology is used to realize the warehousing management, the warehousing management of the logistics distribution center, and the warehousing management of the retail store, the entire supply chain of “shop replenishment demand—distribution center—manufacturer” can be realized. Optimal management of the process.
The use of RFID technology in warehouse management can realize the visual management of all management units, which can greatly shorten the packaging, handling, inventory, and statistics time, thereby reducing cargo damage, accelerating capital turnover, and greatly improving the efficiency of warehouse management.

2.2.1 Warehouse management
When garments are produced from the factory and go through the storage procedures, the staff put the goods on a forklift and send them to the back-end warehouse. If possible, a reader and antenna can be installed on each forklift to identify the RFID tag data. When the forklift brings the goods to the warehouse, it is read by the reader at the door of the warehouse and the tag information is sent to the warehouse The management system records the detailed information of the goods received.
In the warehouse, goods are placed on containers according to their type, such as style or brand. Bar codes are affixed to the shelves for easy identification. In daily life, employees use RFID devices to read cargo labels and shelf barcodes, and associate the goods with the stored shelves. The handsets are embedded with barcode scanners, and the containers use barcodes instead of RFID tags to avoid obtaining them at the same time. The ID numbers of several containers.

2.2.2 Outbound management
Before being treated as RFID technology, the clothing delivery process was handled manually. That is to say, when these garments arrive at the distribution center from the manufacturer, the staff must manually check them one by one, and when the garments are sent to the clothing store, they must be packaged one by one and recorded manually, which results in many errors.
After using the RFID application, the manufacturer’s label is affixed to the clothing item to be sent and verified before delivery, and then an advance shipment notice is issued to the retailer. After the packaged clothing arrives at the distribution center, it will be placed on the conveyor belt. During the transmission process, these labeled packaged clothing will be read by the channel RFID reader. The data after reading is sent to the system, and the software will confirm the ID information. In the event of an incorrect or missing system, a warning will be issued to remind employees to check the clothing goods in the box. After the clothing is repackaged, it is shipped to the clothing store. Before being loaded on the truck, the staff will read the ID number on the tag in the RFID channel according to the packing list, and finally send the advance shipping notice to the clothing store.
Through this process, 15,000 pieces of clothing items can be verified per hour in only one RFID channel. The automation of the verification process can reduce the time a single product spends in the supply chain by 5 to 7 days.

2.3 Warehouse inventory to avoid out of stock and broken codes
For manufacturers and clothing stores, both RFID readers can be used for warehouse inventory. Customers can automatically analyze the tags read by the readers to know the actual clothing of a certain style, color, and model. Quantity, so as to ensure the balance of inventory, and timely replenishment, to avoid the phenomenon of out of stock or broken codes of a certain clothing in the clothing store, and to ensure the normal needs of customers.

Three, logistics management
The benefits of RFID technology in clothing logistics are reflected in the efficiency of logistics management, logistics costs, and delivery control.
The application of RFID technology realizes the standardization of clothing logistics operations, shortens operating procedures and operating time, reduces labor costs, thereby reducing operating costs, increasing the throughput of logistics links, increasing the transparency of supply chain management, and improving logistics management efficiency.
At the same time, the use of RFID can minimize the delivery error rate. Delivery errors mainly refer to the shortage of original boxes and packing box errors. Both of these problems can be minimized by using RFID technology.

Four, store anti-theft
The RFID reader has a relay output function inside, that is, when the reader reads a tag or a tag with a specific format, the reader closes the relay, which triggers the closure of the external relay and starts the alarm or alarm indicator. For RFID Label anti-theft has the following situations:
4.1 Labels in clothing stores need to be recycled
In this case, the reader installed at the door of the clothing only needs to read the tag to trigger an external alarm.
4.2 The label of the clothing store is not recycled
In this case, the clothing store can use the RFID reader to rewrite the label on the clothing that the customer is about to buy, and define a byte of data. When the byte is 0, it means that it has not purchased, and when it is rewritten to 1, it means that it has been purchased. , When the reader at the door reads an unwritten label, it triggers an external alarm to alarm, and when it reads a rewritten label, it does not trigger the external alarm to alarm.

Five, VIP customer management
Clothing stores or clothing factories can use RFIB tags to apply for a membership card for VIP customers, and use RFID readers to automatically call up VIP customer related information, including the business direction of the VIP customer, the previous visits of the VIP customer, and the appointment and negotiation items of the VIP customer And so on, based on this information, you can fully understand VIP customer information and conduct targeted conversations.
Six, system advantages
The advantages of using RFID to intelligently manage clothing are shown in the following three aspects:
6.1 Intelligent supply process management
(1) Order matching: Purchase orders are often delivered multiple times, and orders are frequent. In order to ensure that the order and the arrival of the goods will not cause confusion, they must be matched one by one, and the arrival of each order can be checked at any time. The materials ordered are marked with electronic tags to facilitate the inventory and investigation of the supplier’s product quality problems.
(2) Supply cycle control: In order to ensure the needs of production and sales, and to reduce the inventory backlog of materials, the time of supply must be controlled. Through the supplier’s unique number and service quality certification, the supply time of each material is accurately calculated, and orders can be ordered as needed to ensure immediate production.
(3) Quality tracking: By matching the quality inspection form to the electronic label of the purchased product, the quality responsibility of the supplier can be effectively investigated.
(4) Entrusted processing control: Many manufacturers only operate brands, and generally entrust OEM manufacturers to manufacture and produce, and assign them to various OEM manufacturers to paste on the products through pre-made electronic tags. It is easy to count during acceptance. Any quality problems found in the sales process can be directly investigated to the original manufacturer, and the remaining materials after commissioned processing can also be quickly calculated.
(5) Cargo tracking in transit: Clothing products are commodities with a fast turnover rate. They are often put on the market quickly once production is completed and distributed to counters in various places. During the transportation process, commodities account for a relatively large proportion (including those in various regions). Time transfer). The use of electronic tags as unique identification can accurately track the goods in transit, and can strictly guarantee the arrival time and quantity of the goods.
(6) Payment reconciliation: Many manufacturers use the method of multiple orders, batch orders, and payment at the end of the month. Reconciliation of payables is a very important task. The one-to-one automatic matching method of the unique identification of the order and the unique identification of the payment voucher can make the reconciliation clear and easy, and can automatically calculate the amount payable.
6.2 Intelligent warehouse management
(1) Multi-database collaborative operation: For the needs of circulation, the products of garment industry enterprises are often distributed in different warehouses in various places, so as to transfer goods, allocate goods, and replenish goods. There are also many types of warehouses, such as: finished product warehouse, raw material warehouse, circulation warehouse, turnover warehouse, scattered small warehouses, etc. The inventory of each warehouse needs to be monitored daily 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.
(2) Warehouse receipt, delivery, and inventory operations: The most important task in warehouse 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, The automation of distribution prevents omissions and losses in inventory.
(3) First-in, first-out: Each product has a lifespan. Due to the many types of products, it is difficult to ensure accurate first-in, first-out products through manual records and custodian records in actual warehouse 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.
(4) Out-of-stock alarm: When there is a shortage of a certain product in any warehouse, not only can the alarm be automatically prompted, but also the details of product composition such as model type, color, and size can be subdivided. That is, if a certain size of a certain style is broken, the custodian can immediately be reminded to replenish the goods in time.
(5) Statistics of unsalable products: The backlog of products in the clothing industry is a very headache. Through the statistics of unsalable products, we can get the staying time of each product (subdivided into model, color, size), and we can quickly find out which ones Products that are unsalable or out of season can easily provide price reduction decisions or exchanges to accelerate product sales and capital turnover.
6.3 Intelligent sales management
(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 functions of sales, return, counter inventory, inventory, collection and other sales automation operations; at the same time, it can generate various current-day statistics The report is sent 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, various manufacturers are improving the quality of service and 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. Therefore, 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.
