What is the development trend of electronic tags

Electronic tags have a variety of trends to suit different application needs. Taking the commercial application of electronic tags as an example, since the prices of some products are relatively low, in order to make electronic tags not only increase the cost of goods, the price of electronic tags is required to be as low as possible. Taking the Internet of Things as an example, the Internet of Things hopes that tags not only have the function of identification, but also have the function of perception. In general, electronic tags have the following trends.

Smaller size

Due to practical limitations, the size of the electronic tag is generally required to be smaller than the marked item. In this way, very small items and other special applications place smaller and easier to use labels.The smallest RFID chip with built-in antenna is now only about 0.1mm thick, and the electronic tag can be embedded in the banknote.

Lower cost

In the long run,The market for electronic tags (especially UHF long-distance electronic tags) will gradually mature in the next few years, becoming another market with broad prospects and huge capacity after mobile phones, ID cards and bus cards. Commercially applied electronic tags, when the number of uses is 1 billion, many companies want the price of each electronic tag to be less than 5 cents.

The action distance is farther

Because the working distance of the passive RFID system is mainly limited to the energy supply of the tag, with the development of low-power design technology, the working voltage of the electronic tag will Further reduction, the required power consumption can be reduced to 5 nanometers or even lower. This makes the distance of the passive radio frequency identification system further increased, and can reach a working distance of several tens of meters or more.

Passive readable and writable More perfect performance

Different application systems have different requirements for reading and writing performance and distance of electronic tags. In order to adapt to the occasion of rewriting the tag data multiple times, it is necessary to further improve the read and write performance of the electronic tag, so that the bit error rate and the interference performance are acceptable.

Recognition for high-speed moving objects

For high-speed moving objects, such as trains and cars driving on highways, between electronic tags and readers The communication speed will increase, enabling high-speed moving objects to be identified quickly and accurately.

Multi-tag read/write function

In the field of logistics, there are a number of items that need to be identified at the same time. Therefore, communication protocols suitable for this application must be used for fast, multi-label read/write functions.

The self-protection function is better under electromagnetic field

The electronic tag is in the electromagnetic radiation emitted by the reader Therefore, the electronic tag may be in a very strong energy field. If the electromagnetic energy received by the electronic tag is strong, a high voltage is generated on the tag. In order to protect the tag chip from damage, the electronic tag must be strengthened under a strong magnetic field. Self-protection.

More intelligent and more cryptographic features

In some applications where security is a high priority,The data of the electronic tag needs to be strictly encrypted and the communication process is encrypted. This requires an electronic tag with more intelligence and better encryption features, so that the electronic tag can hide itself without being discovered when the "enemy" appears, and the data will not be acquired without authorization.

With other ancillary functions Labels

In some applications, you need to find a certain tag accurately. In this case, the tag needs to have certain auxiliary functions, such as buzzer or indicator light. . When the system sends an instruction, the electronic tag will give an audible and visual indication, so that a specific tag can be found in a large number of targets. In addition, in other aspects, such as the new type of loss prevention and anti-theft tags, the electronic tag can be hidden or embedded in the article during the generation process.To solve the problem of anti-theft of items in the supermarket.

has a kill function Labels

In order to protect privacy, the reader issues a kill command or the tag destroys itself when the design life of the tag expires or the use of the tag needs to be terminated.

New Production Process

In order to reduce the production cost of the tag antenna,People began to research new antenna printing technology, which can be printed on the product packaging at a cost close to zero. The use of conductive ink to print RFID antennas on the product packaging box is lower in cost than conventional metal antennas, printing speed is fast, space is saved, and environmental protection is beneficial.

with Sensor function

Connecting the electronic tag to the sensor will greatly expand the function and application area of the electronic tag.
