2. radio frequency system refers generally to its frequency of operation greater than 400MHz, and typical working frequency range has: 915MHz, 2450MHz, 5800MHz etc.The data volume that the basic characteristics of radio frequency system are that electronic tag and reader cost are all higher, preserve in the label is big, reading distance (can reach several meters to tens meters) far away, adapts to the objects at high speed Windsor, profile is generally card shape, reading antenna and electronic label antenna that stronger directivity is all arranged.

3. in the active electronic label battery is housed, generally has reading distance far away, weak point is the life-span of battery limited (3～10 years); Nos battery in the passive electronic label, it is converted into direct current with the part microwave energy and works for itself after receiving the microwave signal that reader (readout device) sends, and generally can accomplish non-maintaining.Compare active system, passive system is slightly restricted aspect reading distance and adaptation object of which movement speed.

4. the information in the integrated cured type electronic tag generally is about to information and injects with the ROM technology pattern when integrated circuit is produced, the information of its preservation is unalterable; The information that on-the-spot wired rewriting formula electronic tag is generally preserved electronic tag writes when rewriting in its inner E2 storage portions needs special-purpose programmable device or write device, is necessary for its power supply in the rewriting process; On-site wireless is rewritten the formula electronic tag and generally is applicable to active electron-like label, has specific rewriting instruction, and the information of preserving in the electronic tag also is positioned at E2 storage portions wherein.The time of rewriting electronic tag data generally speaking and being spent is much larger than reading the time that electronic tag spends.Conventional is a second level for rewriting the time that is spent, and the time of reading cost is Millisecond.

The application of automatic identification technology is improving the every aspect of our life just stealthily:

At the supermarket in, the utilization of bar codes technique make ten hundreds of types of merchandize, price, the place of production, batch, each link such as shelf, stock, sale managed in good orderly;

2. adopt the automatic vehicle identification technology, make charge places such as road and bridge, parking lot avoid the vehicle queue phenomenon of being open to the custom, reduced time waste, thereby greatly improved the traffic capacity of communications and transportation efficient and traffic transporting facility;

3. in railway operation, adopt the automatic equipment recognition technology identification information of the train locomotive that goes at express speed, vehicle can be collected on query point automatically and send in the transportation by railroad information management system (TMIS), the Back ground Information that provides car tracing administrative institute timely to need for railway operation;

4. adopt the anti-counterfeiting license plate system of automatic identification technology, will make stolen vehicle Da Bai under the native monitoring system, thereby take precautions against the generation of the stolen case of vehicle effectively;

5. on the production line of robotization, each link of entire product production procedure all is placed under tight monitoring and the management;

6. in the operational management of bus, automatic recognition system writing down exactly vehicle each website along the line to sending out the station constantly, for vehicle scheduling and omnidistance operational management provide real-time reliable information.

The present electronic tag that uses; TI series (American TI Company), I-Code series (Philip, Omron Corp) etc. are arranged; but the radio frequency chip that they use is millimetre-sized; after adding antenna, protective seam or shell; volume is relatively large, has restricted in some littler article or the use in the space.
