Principle and Classification of RFID Handheld Terminal Firstly, Introduction of RFID technology RFID is a kind of non-contact automatic recognition technology, it recognizes object and gets data with the radio frequency signal. It is most used in anti-counterfeiting tracing, warehouse material tracing and workshop producing tracing. RFID is made up by three parts, they are label, reader and antenna. Working frequency of RFID could be divided into LF, HF and UHF. For LF, the frequency is between 30 and 300KHz, 134.2KHz is the most common one. For HF, the frequency is between 3 and 30MHz, 13.56MHz is the most used one. For UHF, the frequency is between 300 and 968MHz, 902-928 MHz is most used scale. Secondly, Characters of RFID   Thirdly, Comparison of RFID and Barcode Penetrability Information Read/write Reading mode Scan Quantity and speed Reuse Barcode NO Small Only Read CCD/Laser Low speed/one NO RFID YES Big Read/Write wireless

Handheld Logistic Express Terminal With the development of social and economy, the competition of logistic express is harder and harder. Requirements are towards diversity and personalization from customers, which brings challenge for logistics companies. It is urgent for logistics to reduce cost and improve efficiency, which affects the development of logistics company. IOT brings the development of logistics companies, which could reduce the cost and time of logistics, as well improve the efficiency of operation. With the usage of IOT, it could build the traceability system, which could track during all processes. Handheld terminal is one kind of IOT, which could be used to position car, monitor products and arrange the dispatch, which could track the products during all processes. Advantages of handheld terminal  (As SEUIC a sample) : --Supports 1D, 2D, RFID, NFC, UHF, GPS, finger-printer and other data collections. --It supports data collection and checking, as well su

Applications of handheld PDA in hospital AUTOID Cruise1 and 9HC are supplied by SEUIC, most used for hospital. Supports usage in water with waterproof .

Application of RFID Handheld Terminal in Library With the development of RFID, RFID handheld terminal is widely used in various industries. Compared to traditional barcode technology, RFID is much automatic, which could improve the efficiency of management. In the library management, RFID handheld terminal could inventory books quickly, which reduce the labor cost. Tagged a RFID label in each book, with the chip and handheld terminal, it could track the information and position by user, which could be borrow or return automatically. When the book input, creates RFID label according to the information of book. With the data, it could print the RFID label with data, and tagged to the books, which could be convenient for checking. RFID handheld terminal collected and uploaded data to the database, which could be tracked with all information in real-time. When reader needs to borrow the book, the system will verify the ID of user, with the verification, user could get into system

City Centers: Handheld Terminal With the development of information and technology, handheld terminal is widely used in various industries, which brings much convenient. Firstly, information acquisition automation Compared to the traditional manual collection, with the usage of handheld terminal, it reduce the time and cost, as well improve the efficiency of data collecting. Secondly, transmission information During the logistics, it could control driver and cars with position, and arrange the route, which reduce the transportation cost. Each product will be inventoried by handheld terminal in each intermediate transit, it keeps the update of products, which could support the check by company and customers. With the usage of handheld terminal, it could control products conditions during all processes. Thirdly, process transparency It could track products during production, such as material, half-finished and finished products, and inventory products in warehouse, with th

Explosion-proof Handheld Terminal With the development of IOT, handheld terminal is widely used in various fields. Petroleum and petrochemical industry is some special, explosion-proof handheld terminal could be used in the management. As the particularity of petrochemical industry, normal industrial handheld terminal could not meet the requirements. With the question, SEUIC has promoted explosion-proof handheld terminal, which could be used for special industries with explosion-proof needs. Explosion-proof handheld terminal are designed specially, with explosion-proof battery circuit, and less current, it could be safe even under the condition of circuit nodes short. Hull of explosion-proof handheld terminal is made from electrostatic prevention, insulation and inflaming retarding material. Explosion-proof handheld terminal are widely used in petroleum and petrochemical industry, gas station, coal industry, mining industry, special gas detection and so on. Characters and adva

Introduction about Protecting Grade of Handheld Terminal IP protection grade is one of the most important standard of industrial handheld terminal, it contains dust protection, external invasion and waterproof grade. IP protection grade is made up by two numbers, first number means grade of dust protection and external invasion grade; second number means airtight degree, such as waterproof. First number of IP protection grade Number Protection Scale Introduction 0 No Protection Can not avoid the outside damage 1 Avoid external invasion with diameter more than 50mm Protect parts away from external things which with big size 2 Avoid external invasion with diameter more than 12.5mm Protect parts away from external things which with middle size, such as fingers 3 Avoid external invasion with diameter more than 2.5mm Protect parts away from external things which with diameter more than 2.5mm, such as wire 4 Avoid external invasion with diameter
