Medical identification  RFID wristband is used to identify and manage patients in electronic medical record system, electronic hospital management system and inpatient management system. Compared with ordinary wristbands, RFID printers can also be used to print and write RFID information. Even if the surface information of RFID wristbands is fuzzy, accurate information can be read through RFID chip . The medical RFID printing wristband can record the basic information of the patient, such as whether the patient has medical taboos, nursing requirements, diagnosis, doctor's order execution records and nursing records, such as whether the patient has received an injection today, whether he has taken medicine today, whether he has had a physical examination today, which can be reflected through the patient's intelligent medical printing RFID wristband, which can greatly improve the efficiency and quality of nursing patients. The advantage of medical RFID wristband is not only that

RFID tags are an important part of the Internet of Things. Using RFID tags, items and fixed assets can be managed quickly, easily and conveniently, saving time and effort. In the RFID fixed asset management system, what is the core? The core of RFID tags 1. Chip: The technology and quality of the chip determine whether the entire RFID fixed asset management system can operate normally. RFID chips are divided into tag chips and reader chips. The chip of the RFID electronic tag integrates all circuits except the tag antenna and matching line, including modules such as RF front-end, analog front-end, digital baseband and memory unit. The basic requirements for chips are light, thin, small, high stability and low price. The development trend of RFID chip design and manufacturing technology will continue to be lower power consumption, longer distance, faster read and write speed, higher reliability and security, and continuous reduction of cost. For domestic RFID chip manufacturers, the m

RFID (radio frequency identification) is an automatic wireless identification and data acquisition technology, which has been widely used in many fields. This paper introduces the performance characteristics of mainstream RFID technology, and analyzes the application trend and technical development trend of this technology in the future. RFID is an automatic wireless identification and data acquisition technology, which has been used for many years and has more and more application fields. Today, smart chips with readable and writable memory that can prevent unauthorized access can be seen in many containers, pallets, product packaging, smart ID cards, books or DVDs. Due to possible applications in the future, RFID is about to usher in a very huge growth period. The global market of this technology, chip, card reader, software and business will grow from US $1 billion in 2002 to US $2.6 billion in 2007. The application will continue to focus on the field of supply logistics. In this f

A typical RFID system is mainly composed of four parts: reader, electronic tag, RFID middleware and application system software. Generally, we collectively call middleware and application software application system. Basic components of RFID Technology 1. Electronic RFID Tags Electronic tag, also known as transponder or smart RFID tag, is a miniature wireless transceiver, which is mainly composed of built-in antenna and chip. 2. RFID Reader RFID reader is a device that captures and processes RFID tag data. It can be an individual or embedded into other systems. RFID reader is also one of the important components of RFID system. Because it can write data to RFID tag, it is called RFID reader. The hardware part of the reader / writer is usually composed of transceiver, microprocessor, memory, external sensor / actuator, input / output interface of alarm, communication interface, power supply and other components. 3. Controller The controller is the command center for the orderly operatio

 With the investment of billions of IOT devices in the market and the growth of trillions of market shares, we have to go through strict consideration in deciding the structural design of edge node sensors or intelligent nodes in order to make the right choice. These micro edge sensors not only provide important data, but also ensure its safety. At the same time, we should adopt the lowest power consumption, cost and occupied space. Some complex processing tasks of edge nodes can be executed in the IOT gateway, which brings not only security intelligence, but also more. The main components of the IOT system include edge node sensors or modules, which are mainly used to collect sensor data. The IOT gateway is used to process and integrate the data of all sensors and maintain the communication connection with the cloud server or other edge nodes. The cloud server is used for non real-time data analysis and storage. Finally, the mobile application is used to render and display the results
