There are three main categories of products derived from RFID tag technology:
1. Passive RFID tag products:
2. Active RFID tag products:
3. Semi active RFID tag products:
As the name implies, it is the combination of active RFID products and passive RFID tag products. It combines the advantages of the two. Under the trigger of low-frequency 125kHz, microwave 2.45G gives play to its advantages, and solves the problems that can not be solved by active RFID products and passive RFID tag products, such as the application of access control management, regional positioning management and security alarm, short-range activation positioning and long-distance data transmission.
Five areas
1. Warehouse / transportation / materials:
The RFID chip is embedded in the goods and stored in the warehouse, shopping mall and other goods as well as in the logistics process. The relevant information of the goods is automatically collected by the RFID reader / writer. The management personnel can quickly query the information of the goods in the system, reduce the risk of abandonment or theft, improve the delivery speed of the goods, improve the accuracy, and prevent the goods from being sold and counterfeited.
2. Access control / attendance
3. Fixed assets management:
Some places with large assets or valuable items such as libraries, art galleries and museums need to have complete management procedures or strict protection measures. When there is an abnormal change in the storage information of books or valuables, the administrator will be reminded in the system at the first time to deal with the relevant situation.
4. Medical information tracking:
Case tracking, waste goods tracking and drug tracking are all good methods to improve the service level and efficiency of the hospital.
5. Military / national defense / national security:
The dynamics of some important military drugs, guns, ammunition or military vehicles need to be tracked in real time.
Seven advantages
1. Super anti-interference
2. The data capacity of buy RFID tags is very large
It can be expanded to 10K according to the user's needs, which is far higher than the capacity of 2725 digits of two-dimensional code bar.
3. It can be operated dynamically
4. Long service life
Because of its strong anti-interference, RFID tags are not easy to be damaged and have a long service life.
5. Conflict prevention
6. High safety
The buy RFID tags(more info) can be attached to the product in any form, and the tag data can be encrypted to improve the security.
Advance and retreat together
Of course, every technology has both advantages and disadvantages. RFID technology has developed to this day, but there will also be defects, that is, the application of UHF technology is not wide enough, the technology is not mature enough, the related products are expensive, the stability is not high, and there is no unified standard in the world.
At present, RFID technology has been closely related to our daily life. In the current Internet of things era, if RFID technology is improved, RFID UHF technology is mature, and RFID UHF market development is widely used, the development of the Internet of things will also be pushed to a new height.
