Compared with the traditional magnetic card, IC card or barcode recognition method, RFID has the characteristics of long-distance and non-contact identification, and has strong adaptability to the environment. Through reasonable design, it can work in various harsh environments and has excellent recognition effect. RFID identification work does not require manual intervention, and is suitable for realizing automatic data collection of the system. At the same time, it can recognize high-speed moving objects and recognize multiple electronic tags at the same time, and the operation is quick and convenient. RFID truck frame management application technology is precisely using RFID technology to manage these points.
 

Smart retail cabinets can be opened and taken, that is, take away, each layer is replaced by an UHF RFID antenna, and an RFID electronic tag is attached to each product for automatic real-time reading. The quantity and attributes of the goods in the vending machine.
The specific shopping process is: Step 1: The user downloads the APP (or WeChat, Alipay applet) with the smart phone. After registration, the user has the right to open the vending cabinet door lock by scanning the QR code. After opening the door, the user can directly take the smart. Goods in the vending cabinet. The second step: the selection of goods, not much to say here, the selection process is no different from ordinary supermarkets or ordinary sales containers. The third step: closing the door payment, closing the door after the purchase of the goods, the smart retail cabinet starts the internal inventory program, using fixed RFID reader to identify the RFID electronic tag inside the cabinet, the end of the inventory can know what the user is taking, on the mobile phone the settlement is completed on the APP.
 

The bottlenecks and opportunities that RFID technology will face in IoT applications. In the definition of the Internet of Things, RFID, sensors, and barcodes are used to acquire object information anytime and anywhere, and then the object information is transmitted accurately and accurately through the network. Finally, the cloud is used for analysis and processing, and then various intelligent objects are implemented. Control and management has become an important foundation for many smart applications in recent years. For example, in the home Internet of Things application, the faulty refrigerator can be identified through the sensing device, and the fault message can be transmitted to the remote service server, so that the maintenance personnel can take the initiative to the household to perform the refrigerator repair.
 

Traditional supermarkets provide us with convenience, but it is not difficult to find out, such as the supermarket price tag replacement is not timely or error, the supermarket goods are frequently stolen, the variety of perishable goods can not be monitored and replaced in time, etc. With the maturity of the Internet of Things technology, these problems will be well resolved.
1. Intelligent price tag system
The price tag in the smart supermarket will be replaced with an LED display, and an RFID tag will be attached to each item, and an UHF RFID antenna and a microcomputer processor will be installed on the shelf. When the tally is placed on the shelf, the multiple RFID reader detects the item and contacts the price control system to return the latest price to the on-board microcomputer processor, which is then quickly displayed on the LED display.
2. Inventory control system
When a consumer attaches an RFID tag-equipped product to a shopping cart with an RFID reader device, the system uploads the information to the Internet of Things control system, and the system immediately analyzes the sales speed and sales status of the product, and contacts the season. A series of dynamic factors, such as festivals and stocks, have developed a scientific supply plan and strive to “zero inventory” of commodities.
3. Smart shopping cart
Install a microcomputer processor with an electronic antenna on the shopping cart. When the RFID-changing product leaves the shelf and is placed in the shopping cart, the product has been recorded by the shopping cart. When you finish shopping, just take out the product. The bank card is lightly brushed at the location of the supermarket, and the settlement is completed, eliminating the need for the cashier to scan each handheld terminal.
 

The UHF RFID market has a wide application scenario, and has the advantages of being able to read multiple tags at one time, recognizing a long distance, transmitting data speed, reliability and longevity, and withstanding outdoor harsh environment. Can be used for asset management, production line management, supply chain management, warehousing, anti-counterfeiting traceability of various items (such as tobacco, alcohol, medicine, etc.), retail, vehicle management, etc.
Vehicle management

The intelligent bucket management system is based on RFID technology and consists of modules such as antennas, card readers, tags, and application systems.
The principle is as follows: the card reader sends a modulated signal of a certain frequency containing information through the antenna; when the tag enters the working area of the RFID tag reader, the antenna generates an induced current through coupling, thereby providing a corresponding tag for the tag. At this time, the tag determines whether to respond according to the information sent by the UHF RFID reader, whether to send data; when the card reader receives the signal sent by the tag, after demodulation and decoding, the tag is internally The data is identified and sent to the application.
 

Utilizing the many different characteristics of UHF RFID, people have developed a series of applications in logistics management, electronic payment, anti-counterfeiting, security access control, intelligent transportation, electronic business cards, traditional media development, rapid access, animal and plant management, indoor Fields such as navigation have been widely used.
1. Logistics
The Internet of Things, first of all, rises in the logistics industry. In order to overcome the shortcomings of traditional logistics, the logistics system now uses a combination of radio frequency identification devices, sensors, GPS (Global Positioning System) and the Internet to form a large network for intelligent logistics management.
Because the UHF RFID reader and tag has the characteristics of reading and writing, no direction, no damage, long-distance reading, and simultaneous reading of multiple items, it can greatly improve the record collection speed and accuracy of the information of the inbound and outbound products, and reduce the artificial errors, improve the speed and accuracy of the inventory.
 

Power plants, coal yards, garbage dumps and other units will have a large number of materials transport vehicles entering and leaving every day. It is necessary to carry out procedures such as parking, registration, weighing, etc. The operator manually records the data into the computer, which is time consuming and has a large error rate. It is also easy to breed human fraud and cause a lot of economic losses to the company. The RFID weighing tag is placed on the car, and the relevant data is read by the UHF RFID reader to correspond to the vehicle, which provides great convenience for the staff.
The system includes long range RFID readers, antennas, tag cards, electronic truck scales, main engines, signal lights (red, green), automatic gates, ground sense coils, infrared instruments and supporting management software.
When the green signal light is on, the weighing vehicle enters the lane, and after the vehicle enters the lane, the red signal light is on, prohibiting the next vehicle from entering the lane. The vehicle passes through the induction coil to generate a sensing signal. After the Ethernet RFID reader reads the card, the card information is uploaded to the host database, and the vehicle information is called out.
