One article unveils the mystery of RFID

When it comes to RFID, many people don’t know what industry it is. Many friends who are not in the industry may be confused and curious to ask what RFID is? In fact, RFID is a professional term. I believe it will not be so unfamiliar from the application scenarios of RFID. Residential communities use keychain Access Control, bus cards, ID Cards, automatic identification of vehicle entry and exit in the community, and the most popular unmanned retail in recent years. These The application scenarios all feel that RFID is actually very relevant in our lives. In fact, RFID is not mysterious at all, but the English abbreviation sounds "high-end". RFID (Radio Frequency Identification) is actually used in all aspects of our lives, especially warehousing, logistics, vehicles, personnel, positioning, etc., becoming data. A great helper for information collection.

For example, barcodes are widely used in retail Stores. Barcodes have changed the face of the entire Retail Industry, and the concept of RFID is the same. The difference is that RFID has a wider range of applications, is suitable for harsh environments, and has more data. The disadvantage is that it is more expensive. . Barcodes are printed on the outer packaging of goods and store a certain amount of information, but they are not suitable for harsh environments and cannot meet industrial needs. RFID solves these problems, but it is not suitable for one-time low-price products due to cost considerations.

Commonly used bus cards and ID cards for travel are RFID carriers that store a lot of personal information inside. They are also sturdy, durable, and easy to carry. Think about how inconvenient our lives would be without these.

In the transportation industry, dozens of tons may be transported at a time, and thousands of tons of goods may be dismantled in warehouses. If you rely on manual counting, it will be time-consuming, laborious, and error-prone. However, as long as RFID tags are installed and identification handheld devices are used, goods and raw materials can be quickly counted. , accessories, etc., achieving great liberation of manpower and material resources.

We can now buy a wide range of products in supermarkets thanks to the transportation and manufacturing industries. If RFID is not introduced to reduce costs, the products people buy every day will not be of high quality and low price.

The industrial upgrading of Industry 4.0 promoted in recent years is committed to making production lines intelligent and automated. This can only be achieved by introducing RFID. RFID is the cornerstone of Industry 4.0. Although we do not talk about RFID in our lives, it is undeniable that , the current great abundance of material resources is due to the batch and intelligent production.

Generally speaking, RFID radio frequency identification technology has many characteristics:

Applicability: RFID technology relies on electromagnetic waves and does not require physical contact between the two parties. This allows it to establish connections and complete communications directly regardless of dust, fog, plastic, paper, wood and various obstacles.

Efficiency: The reading and writing speed of the RFID system is extremely fast, and a typical RFID transmission process usually takes less than 100 milliseconds. High-frequency RFID Readers can even identify and read the contents of multiple tags at the same time, greatly improving the efficiency of information transmission.

Uniqueness: Each RFID tag is unique. Through the one-to-one correspondence between the RFID tag and the product, the subsequent circulation of each product can be clearly tracked.

Simplicity: RFID tags have a simple structure, high recognition rate, and simple reading equipment. Especially as NFC technology becomes more and more popular on smartphones, every user's mobile phone will become the simplest RFID reader.

As one of the core key technologies of the Internet of Things, RFID has been increasingly used in the industry in recent years. For item management and labor cost control, RFID technology has become the best bridge for collection. RFID is widely used in many traceability and anti-counterfeiting application fields such as industrial automation, commercial automation, transportation control management, etc. The types of RFID radio frequency identification technology products will become more and more abundant, their applications will become more and more extensive, and they will continue to maintain the momentum of rapid development.
