RFID information details, Six areas, Seven advantages

Radio Frequency Identification RFID  is a kind of automatic Identification technology, no contact the bidirectional data communication by way of Radio Frequency, using Radio Frequency way to recording media (electronic tag or rf card) for reading and writing, so as to achieve the aim of identifying target and data exchange, the products are mainly derived from the RFID technology has three categories:

 

Passive RFID products:

Such products require close contact identification, such as rice card, bank card, bus card and id card, etc. All of these cards require close contact during work identification. The main working frequencies include low frequency 125KHZ, high frequency 13.56mhz, uhf 433MHZ and 915MHZ.This kind of product is also quite common in our life, but also the development of early products.

 

Active RFID products:

This type of product has the characteristics of remote automatic identification, so it is correspondingly applied to some large environments, such as intelligent parking lot, smart city, intelligent transportation and Internet of things, etc. Their main work includes 2.45ghz and 5.8ghz microwave, and 433MHZ uhf.

 

Semi-active RFID products:

As the name suggests is a combination of active RFID and passive RFID products, it combines the advantages of both under the low frequency of 125 KHZ frequency trigger, let the microwave 2.45 G advantage, solved the active RFID and passive RFID products can't solve problems, such as entrance guard management, area management and security alarm localization of the close to activate positioning, remote data transmission.

 

RFID is widely used. RFID technology is characterized by strong anti-interference and no manual identification, so it is often used in some fields that need to collect or track information, including but not limited to the following six points:

 

Warehouse/transport/supplies

The products are embedded with RFID chips and stored in warehouses, shopping malls and other goods as well as in the process of logistics. The information related to the goods is automatically collected by the reader, so that the management staff can quickly query the information of the goods in the system, reduce the risk of discarding or theft, improve the delivery speed of the goods, improve the accuracy, and prevent goods from transshipment and anti-counterfeiting.

 

Access control/attendance:

Some companies or some large meetings, by inputting the identity or fingerprint information in advance, can automatically identify and sign in through the door identification system, which saves a lot of time and labor, also very convenient.

 

Fixed assets management

For places with large assets or expensive items, such as libraries, art galleries and museums, it is necessary to have complete management procedures or strict protection measures. When there are abnormal changes in the storage information of books or valuables, the administrator will be reminded in the system at the first time to deal with relevant situations.

 

Train/car identification/baggage security check:

China's railway vehicle dispatching system is a typical case, automatic identification of vehicle Numbers, information input, save a lot of manual statistics time, and improve the accuracy.

 

Medical information tracking:

Case tracking, waste tracking and drug tracking are all good ways to improve the level and efficiency of hospital services.

 

Military/national defense/national security

Important military drugs, guns, ammunition or military vehicles need to be tracked in real time.

 

Rfid technology can be widely used in a number of industries and fields, there must be its "advantages", generally speaking, rfid technology has the following advantages:

Strong anti-interference, it has one of the most important advantages of non-contact identification, it can work in sharp and harsh environment, can and penetrating power, can quickly identify and read labels.

 

The data capacity of RFID tags is very large, which can be expanded to 10k according to the needs of users, much higher than the capacity of 2725 Numbers of qr code bar.

 

It can be dynamically operated, its tag data can be dynamically modified by programming, and it can be dynamically tracked and monitored, as long as the object attached to the RFID tag appears within the effective identification range of the reader.

 

Long service life, because of its strong anti-interference, so the RFID tag is not easy to be destroyed, the service life is very long.

 

Anti-collision, in the reader's effective identification range, it can read multiple RFID tags at the same time.

 

High security, RFID tags can be attached to the product in any form, can be used for tag data encryption, improve security.

 

The identification speed is fast. As soon as the RFID tag enters the effective identification range of the reader, the data will be read immediately. In general, the identification can be completed in less than 100 milliseconds.

 

Of course, every technology has its advantages and disadvantages. The development of RFID technology to today also has its drawbacks. That is, the application of uhf frequency band technology is not wide enough, the technology is not mature enough, the relevant products are expensive, the stability is not high, and there is no unified standard in the world.

 

At present, RFID technology is closely related to our daily life. In the Internet of things era, if RFID technology is improved, RFID uhf technology is mature, and RFID uhf market development is widely applied, then the development of the Internet of things will be pushed to a new height.
