See radio frequency identification (RFID) technology in many lives, many masters of China

My Government in 1993, developed by Golden card project implementation plan, is a designed to accelerate our national informatization of major national projects, from a variety of automatic identification technology development and application of very rapidly.

Now, radio frequency identification (RFID) technology as a new kind of automatic identification technology, is also popular in China quickly. At present, China's RFID technology in the following application development prospects. Of course, here just listed application of RFID technology. Any kind of technology if you have widespread, would spawn a huge market. RFID is the future of a new economic growth points.

1 safety areas

(1) the access control security

Future access security system applications RF cards.

A card can be used. For example, you can make the work permit, passes, parking cards, hotel accommodation and other tourist passport card or even, the goal is to identify the identity and security management, fees, etc. The benefit is to simplify access to procedures, improve work efficiency, safety and protection. As long as the person wearing the packaged as ID card size of RF cards, access to entrances have a reader, personnel access to automatically identify the identity, the illegal intrusion would be alarming. Security level requires a high place, can also be combined with other forms of recognition, fingerprint and PalmPrint or facial features into the RF card.

Companies can also be used for RF card protection and tracking property.

The RF card attached to the items above, such as computers, fax machines, photocopiers or other files, laboratory supplies. The RF card allows the company to automatically track to manage these valuable property, you can track an item from one building to leave, or alarm mode limits the goods leave the place. Combined with GPS systems use radio frequency card, you can also wait for container trucks, cargo and effectively track.

(2) car alarm

This is a new application of RFID.

Currently has developed enough small, able to encapsulate the car keys which contains a specific key word in the RF card. It needs to vehicles fitted with the reader, when the key is inserted into the ignition, the reader can identify key identity. If the reader not receive RF card sent to a specific signal, the car's engine will not start. With this kind of electronic authentication methods, the car's central computer and will also be able to easily prevent short-circuit ignited.

Another vehicle anti-theft system, drivers themselves with a RF card, its transmission range is in the drivers seat 45 ~ 55cm, the reader is installed on the seat back.

When a reader reads a valid ID number, the system produces three acoustic song, then you can start a car engine. The anti-theft system there is another powerful feature: If a driver leaves the car and the car door open or shut down the engine, then the reader will need to read another valid ID number; if the driver of the car radio cassette off, so the reader can't read valid ID number, the engine will automatically turn off, and trigger alarm.

(3) electronic article surveillance system

Electronic article surveillance system (ElectronicArticleSurveillance, EAS) aims to prevent the commodity being stolen.

The entire system including the object of a memory capacity of only 1 bit (i.e., on or off), RF card, and the reader at the store. RF cards are activated at the time of installation. In the activation state, RF card close to the scanner will be detected and the police. If the goods are purchased by the sales personnel with special tools for removing RF card (typically in the clothing store), or with a magnetic field to make the RF card failure, or directly undermine the RF card itself electrical characteristics. EAS system has been widely used. According to the estimated annual consumption of 60 million sets.

2 production sales areas

(1) production line automation

Using RFID technology in production lines to achieve automatic control, monitoring, improved productivity, improved production methods, saving costs.

For example to illustrate the application of RFID technology on the production line.

For automotive assembly line.

Germany BMW AG in assembly line on the application of RF card, to a large number of users as possible to the production of customized automotive. BMW's production is based on the user's request style and production. Users can choose from thousands of internal and external options, select how you want your car's color, engine type and tire pattern, etc. Thus, automobile assembly line, you have to assemble hundreds of styles of BMW cars, if you do not have a highly organized and complex control system is very difficult to complete complex tasks. BMW in its assembly line is equipped with RFID systems use reusable RFID card. The RF card with all car detailed requirements in each point has a reader, so you can ensure the car in various location, can not pipeline error to complete Assembly tasks.

(2), warehouse management

Will RFID system for intelligent warehouse management, can effectively address and information about the flow of goods management, not only increases the speed of processing goods, also can monitor all the information of the goods.

RF card affixed to the goods by the warehouse door edge, readers and antennas are placed in forklift truck, each of which the goods are posted all the barcode barcode, the information is stored in the warehouses of the central computer, and the goods related information can be found in the computer. When the goods out of the library, by another reader identify and inform the central computing in which it is placed on the trailer. In this way, the Central Administration can real-time insight into how many products have been manufactured and sent a number of products.

(3) products anti-counterfeiting

Counterfeit issue throughout the world are headache, RFID applications in the security field has its own technological advantages.

Anti-counterfeiting technology itself requires low cost, and difficult to counterfeit. RF card costs are relatively inexpensive, and chip manufacturing need expensive chip factory, forged infringers. RF card itself have a memory, you can store, modify andProduct-related data, facilitate vendor use; volume is small, easy-to-product packaging. Like computers, laser printers, TVs and other products can be used.

(4) RFID card fees

The various transactions abroad are accomplished using a variety of cards, and cash transactions in China generally.

Cash transactions not easy nor safe, but also prone to tax loopholes. The current charge card use magnetic cards, IC cards, and RF card also began to dominate the market. The reason is that some severe environment, magnetic cards, IC cards are easily damaged, and RF card is not easy to wear, I will fear no static electricity and other circumstances; at the same time, the RF card to use convenient, fast, even without opening the package, in the reader wobbled, completed tolls. In addition, you can identify a few of the cards. parallel bus fare, such as the e-ticket. China's largest city bus exception overcrowding, poor environmental conditions, the use of radio frequency card helps to improve the situation.
