Because of Portable Handheld RFID Reader, we can pass through some daily channels and pass the ticket inspection efficiently, saving a lot of time; Because of the Portable Handheld RFID Reader, during this period, the medical staff can carry out data collection in many scenes without contact and with high efficiency, greatly improving the work efficiency of fighting the epidemic and saving people. The work to be completed in 2008 includes: the draft standard for 840-845mhz and 920-925mhz frequency tags, the test method for the basic electrical characteristics of 13.56mhz/ RFID tags, the test method for 13.56MHz RFID readers / writers, and the draft standard for the test method for the physical characteristics of RFID tags. As a data carrier, electronic tags can play the role of identification, object tracking and information collection. In foreign countries, electronic labels have been applied in a wide range of fields. The RFID system composed of electronic tag, Handheld RFID Reader, antenna and application software is directly connected with the corresponding management information system. Quick search and positioning of goods: when it is necessary to search for a certain goods, enter the relevant goods information in the handset, and scan the goods within a certain range. When the goods are scanned, the intelligent warehouse management system will send a prompt to facilitate the quick search of the goods.

The application of radio frequency identification (RFID) can fundamentally solve the above problems. Based on radio frequency identification (RFID) technology and according to the actual situation and needs of warehouse management, oprfid technology has developed an RFID intelligent warehouse management system.

RFID is the abbreviation of radio frequency identification, namely radio frequency identification. It is a non-contact automatic identification technology. RFID can be traced back to the Second World War (about 1940). At that time, its main function was to distinguish the enemy from the British aircraft. In recent years, with the development of large-scale integrated circuit, network communication, information security and other technologies, as well as the promotion of Wal Mart, the world's leading retailer, RFID has been rapidly applied to smart grid, transportation, logistics industry, medical health, fine agriculture and animal husbandry, finance and service industry, industry and automatic control, smart home, environment and security detection, public security, national defense, smart city and other industries and fields. UHF Handheld RFID Reader is to automatically identify the target object and obtain relevant data through RF signals. It is mainly composed of electronic tag, reader and antenna. Tags are composed of coupling elements (also known as antennas) and chips. Each tag has an electronic code (EPC), and the chip can store specific serial numbers and other information. The reader is the bridge between the tag and the software system. On the one hand, it reads the tag information, and on the other hand, it communicates the reading results with the software system. The antenna exists in the tag and reader and is responsible for data transmission from the tag chip to the reader and then to the software system.

RFID technology is divided into low frequency, high frequency, ultra-high frequency, active, etc. RFID technology has the characteristics of non-contact, fast scanning, high identification efficiency, not easy to be damaged, suitable for harsh environment, convenient operation, fast reading and writing speed, large amount of information storage, one card multi-purpose, anti-collision, good security encryption performance, reusability, tracking and positioning, etc.

Android Handheld RFID Reader is the single product stage, that is, each product has a dedicated RFID tag. As each product has its own logo, it can realize the minimum unit management of commodities, and play a great role in retail links, anti-counterfeiting, anti-theft, and consumer behavior analysis. It not only increases the number of goods processed in a day, but also monitors all information of goods. Among them, there are various forms of application. Labels can be pasted on goods and read and written by readers on forklifts and at corresponding positions in warehouses; Barcode and electronic label can also be used together. Sales channel management, the establishment of strict and orderly channels, and the efficient management of purchase, sales and inventory are the strong needs of many enterprises. The product is embedded with an electronic label during the production process, which contains a unique product number. The manufacturer can monitor the flow of the product with an identifier. Wholesalers and retailers can identify the legitimacy of the product with a reader provided by the manufacturer. The rapid development of e-commerce, Internet of things and other fields is undoubtedly the driving force of warehousing and logistics. Nowadays, the storage management mode has shown an intelligent trend. RFID technology will greatly improve the level of warehousing and logistics management, and can speed up the information construction of warehousing and logistics management.

By using RFID technology, improve the efficiency of warehouse management and provide the accuracy of WMS system data. The main objectives are as follows:

Reduce human operation leakage, improve management level and reduce potential safety hazards;

Real time data acquisition, keeping the consistency of items and records in time;

Reliable and stable data acquisition and accurate data;

The statements are manually sorted and summarized and then completed by computer;

Improve the efficiency of data management, timely register the detailed accounts of various safety tools and instruments, and achieve the consistency of accounts, materials and cards;

The Android Handheld RFID Reader system is flexible and has expansion function;

The Android Handheld RFID Reader system is practical and easy to operate for users with different levels of professional quality.

However, for most small and medium-sized warehouses, Android Handheld RFID Reader with complete functions and easy operation are generally preferred. There are obvious differences between the two. In the agricultural field, the Internet of things is widely used, such as surface temperature detection, poultry living conditions, crop irrigation monitoring, soil pH change, precipitation, air, wind force, nitrogen concentration, soil pH and land humidity, to make reasonable scientific estimates for farmers in disaster reduction, disaster resistance Scientific planting and other aspects provide great help to improve the comprehensive benefits of agriculture. Intelligent transportation, with image recognition technology as the core, makes comprehensive use of radio frequency technology, tags and other means. All the goods in the warehouse are transferred and stored in pallets. Through the electronization of pallets, the identity of each pallet can be identified, and the real-time tracking of storage and transfer positions can be realized. Combined with the electronic (digital) warehouse location management, it can provide the necessary data foundation for visual and intelligent warehouse management.
