QR code and RFID in the IOT world

Iot, as its name implies, is the Internet of Things. Iot is developed on the basis of the Internet. People are the subjects on the Internet, while Iot is specific things that are extended to human life, such, A car, a bed, a microwave oven, or even a house. Any object can be covered in this network, so as to realize information exchange between things and between people, so as to achieve intelligent identification, positioning, monitoring and management of the object.
One of the core Iot technologies is RFID Radio Frequency Technology, which is an automatic identification technology. It uses RF signals to automatically identify the target object and obtain relevant data. manual intervention is not required for identification. This technology is the key to achieving information exchange between things. RFID technology has been applied in many fields and is also concerned with the development of IOT, especially the application of RFID technology. However, in recent years, RFID has been in an awkward situation, and its root cause is the cost. RFID technology is not only costly, but also requires the cooperation of a complete set of related equipment for its application, which undoubtedly increases the cost. This has become a weakness of many industries.
The stagnation of RFID makes many people see the unlimited market prospect of QR code application. As a result of advances in bar code technology, the QR code achieves information storage in both horizontal and vertical dimensions, which not only increases the information storage capacity, but also enriches the Information Storage types, although the QR code is difficult to compare with RFID in terms of information volume and read efficiency, due to its low cost and flexible application, the QR code has become a new favorite of the market at a time, and it has replaced RFID, therefore, some people think that there is a market survival game between RFID and QR code.
QR codes have a common relationship with RFID. They can all act as item tags, allowing integrated management of object information. Both have their own advantages and disadvantages, but this does not mean that the two have a survival game. Cai lei, CMO of 2weima.com, said: "The QR code and RFID are really good brothers in the Internet of Things world. They have their own highlights. The QR code facilitates people's daily lives, RFID makes up for the shortcomings of the QR code. Even the combination of the two swords can achieve better results ."
With the development of mobile Internet, mobile Internet access has become a necessity for more and more people to live online at any time. However, complicated websites have become a headache. The application of QR codes can solve this problem. You only need to use a mobile phone camera to align with the QR code and get links to related websites, then, you can quickly log on to the website. This application can be combined with SNS and LBS to better improve the user experience and truly enable access to the internet anytime and anywhere, thus connecting online and offline life. For RFID, its advantage lies in its ability to remotely read data and read multiple pieces of object information at the same time. It has a large scope of recognition and can respond to harsh environments. It is very suitable for applications in a relatively large automated production pipeline. Through the RFID system, all stages of the entire product production process are under strict monitoring and management, similarly, in harsh environments such as dust, pollution, cold, and hot, the use of long-distance radio frequency identification technology shows a hero. Such applications give full play to their respective technical features. It can be said that the two are irreplaceable in different applications. The main application highlight of the current QR code is the combination of the Internet and consumer identification to promote market operation. RFID is more inclined to the high-end technical field. First, the cost can be ignored, while meeting the higher technical needs of the relevant fields. In some application industry applications, we can also combine them to play their respective roles and achieve better results. For example, the two-dimensional codes in the transportation system coexist with the radio frequency technology, which enables remote monitoring and convenience for citizens to solve their own traffic problems.
