一、 Those you do not know the knowledge of RFID

In today's ever-changing technology, our lives are surrounded by a variety of smart devices, and most of the devices operate without RFID tags. It is like an invisible assistant in our lives, quietly working around us, so that our lives become more convenient. So, what is RFID tags? How does it work? In what areas has it been applied? How will the future development trend? Let's unveil the mystery of RFID tags!

1. The development of RFID tags

The development of RFID tags has probably gone through the following stages:

1. Initial period (1940s-1970s): RFID technology originated during World War II and was initially used for military purposes. 1948, engineer Léon Theremin invented the world's first passive RFID device, marking the initial technical development of RFID.

2. Development period (1980s-1990s): In the early 1980s, the push for ISO standards led to the standardization of RFID technology. In the 1990s, RFID technology was gradually applied to the business sector, especially playing a key role in supply chain and logistics management.

3. Maturity (2000s-2010s): Over time, the cost of manufacturing RFID tags has gradually decreased, making the technology more economical and practical. Since the 2000s, RFID technology has been widely used in retail, manufacturing and logistics.

Innovation period (after 2020): In the last few years, RFID technology has been integrated with new technologies such as the Internet of Things and Artificial Intelligence to continuously improve and innovate.

2. How RFID tags work

RFID tags usually operate at 13.56MHz, but there are also RFID tags in other frequency bands, such as 433MHz, 915MHz, and so on. It does not need a built-in power supply, but gets its energy by receiving radio waves sent by the reader. When the reader sends a signal of a specific frequency to the tag, the circuitry inside the tag is activated and sends the information stored in the tag back to the reader. This process is like a conversation between two people, where one sends out a sound and the other hears it and responds. There is no need for physical contact between the reader and the tag, only in the range of electromagnetic waves can be communicated.

3. Application areas of RFID tags

RFID tags are used in a wide range of applications and permeate almost every aspect of our lives.

1. Retail industry: used for inventory management, anti-theft and settlement, improving inventory management efficiency and realizing self-service checkout.

2. Logistics industry: Improve the efficiency of logistics, real-time tracking of the location and status of goods, for intelligent warehouse management.

3. Medical industry: to manage patient identity, medical records and drug information, to improve the quality of medical services, for medical device management.

4. Transportation industry: used for automatic vehicle charging, parking lot management, and improving the efficiency of traffic management.

5. Livestock industry: through the implantation of RFID tags in livestock, to check the health status of animals at any time and improve production efficiency.

6. Library: RFID tags embedded in books to easily realize self-service borrowing and inventory management, and improve the efficiency of library operations. Utilizing RFID technology to establish an automatic book return system to simplify the return process.

7. RFID technology is used in guest room access control system to provide more secure and convenient access control. Tag attached to the luggage, you can always track the location of luggage to reduce the risk of loss

8. Smart home: RFID tags are applied to household goods to realize the tracking and intelligent management of goods.

9. Intelligent access control system: RFID technology can be used for home access control system to provide a safer home environment.

4. The future development trend of RFID tags

In the future, RFID technology will undergo an all-round evolution, providing strong support for various industries to move towards a more efficient and smarter direction. The high-precision development of tags will be in the printing industry to give it more accurate information transfer, improve the quality of the printed page. At the same time, the increase in production speed will make RFID tags faster into the production line, accelerate the production process and reduce costs.

In the intelligent aspect, RFID technology will deeply integrate artificial intelligence, through automatic identification, processing and optimization of design or image, promote more intelligent and efficient production process. The development of digitalization will promote RFID tags to achieve comprehensive digitalization, including automation, data analysis and monitoring and other aspects of innovation, to provide more efficient solutions for enterprises.

Eventually, RFID tags will be more widely used in a variety of fields, including retail, manufacturing, industry, etc. RFID for the industries to provide more efficient, more accurate, more intelligent support. This comprehensive development trend will lead RFID technology into a more innovative and widely used in the new era.
