Internet of Things information is no longer strange, RFID technology has become an important perception layer of Internet of things. In this era of the Internet of Things, RFID technology is one of the key technologies of data connection and data exchange. Before understanding RFID technology, it is necessary to understand the composition of RFID, RFID system includes: TAG, Reader and computer and its application software. The main function of the electronic tag is to complete the communication with the radio frequency antenna. The main function of the reader is to read or write the information of the electronic label. The function of the computer and application software is to connect the external computer through the communication interface of the reader, or to connect the host system of the upper computer, so as to realize the exchange of data.

RFID technology is also known as radio frequency identification technology, it is a kind of radio signals to identify a specific target and read and write the relevant data, without the identification system and the specific target to establish mechanical or optical contact between the communication technology. RFID and the same information identification technology on behalf of the bar code technology compared, more advantages, more prospects, has been widely used in various industries.

1. Read data in batches

In terms of information reading, RFID does not need to see, nor does it ignore the blocking of objects. It only needs to complete the reading and writing of RFID data within the scope of the RFID reader. RFID also has the advantage of mass data reading, can quickly read more than thousands of RFID tag data information, high efficiency.

2. Flexible form

RFID tags can be made in different shapes and sizes, without the need for fixed materials and attachments for accurate reading. Nowadays, with the progress of technology, more small and unique RFID tags have been introduced to meet the needs of different types of industry and product information recognition.

3 Wide read range

The reading range of RFID data information can be increased in different degrees according to the power of the reader and the antenna, and the accurate reading within a range of 10 meters can be achieved. Compared with the traditional identification technology, it has more scope advantages.

4. High security

RFID tags can encrypt the information of the chip. At the same time, RFID tags are unique and cannot be copied. By writing specific information in the RFID tag and binding with the item, it can play the role of anti-counterfeiting and effectively eliminate the appearance of fake and shoddy products.

5. Long lasting

RFID is waterproof, anti-alcohol, anti-corrosion, anti-magnetic, high temperature resistance, anti-pollution and other characteristics, can maintain normal work in harsh environment. And different RFID tags, information storage time can reach several years to decades, very durable.

6. Data storage

One dimensional barcodes have a capacity of 50Bytes, two dimensional barcodes have a maximum capacity of 2953Bytes, and RFID has a maximum capacity of several MegaBytes. With the development of memory carrier, the capacity of data storage is also expanding. RFID can also be repeated to add, modify, delete the data stored in the RFID tag, convenient information update.

The carrier of RFID technology is generally waterproof, antimagnetic, high temperature resistance, to ensure the stability of the application of radio frequency identification technology. RFID technology has advantages in real-time data update, information storage, service life, work efficiency, security and other aspects. Under the premise of reducing manpower, material resources and financial resources, RFID can be more convenient to update the existing data, making the work more convenient. RFID technology stores information according to computers and other information, up to several megabytes, can store a lot of information, to ensure smooth work. RFID technology has a long service life and can be reused as long as the staff pays attention to protection.

With the rapid development of the new generation of high-tech technologies such as the Internet of Things, big data, cloud computing, artificial intelligence and 5G, RFID technology has also achieved unprecedented development. RFID technology changes the inconvenience of information processing in the past, realizes the simultaneous identification of multiple targets, and greatly improves the work efficiency; Electronic tag has a unique code, not easy to forge, high security. RFID technology has been recognized and used in many fields. It is believed that in the near future, RFID technology will penetrate into all aspects of People's Daily life and work, bring more huge social and economic benefits, and make our life more beautiful.
