Knowledge of radio frequency identification of laser anti-counterfeiting labels

Laser security labelIt is a relatively novel anti-counterfeiting technology, which has developed very rapidly in recent years. Both wineries and the electronics industry like to use this technology. There is a radio frequency identification system in this laser anti-counterfeiting label, which raises the anti-counterfeiting identification method to a level. This radio frequency identification system has been noticed since the anti-counterfeiting laser mark was put forward, and it has been realized by the continuous improvement of holographic technology. Let's take a look at the radio frequency identification system of the laser anti-counterfeiting label.

Although laser anti-counterfeiting labels have only been developed in recent years, radio frequency identification systems have appeared in people's lives in the 1990s. It can transmit signals through electromagnetic waves without direct contact to identify objects in motion. The initial application is not on laser anti-counterfeiting labels, but on supermarket item control. In the supermarket, a product with radio frequency identification will be taken out without paying for a warning. This is also the use of its technology. At the beginning, when proposing the idea of ​​anti-counterfeiting laser mark, experts thought that this technology might solve some technical problems. When the later holographic technology matured, some technical bottlenecks were broken, and radio frequency identification was used in tags. When the RFID tag is in the effective range of the signal, according to the principle of electromagnetic induction, the tag antenna will generate an induced current, and the laser anti-counterfeiting tag will work. Then the RFID tag chip recognizes the information and sends feedback information. The identification code of each chip is unique, and only readers with the same identification code library can correctly identify it.

The above is an explanation of the knowledge of radio frequency identification of laser anti-counterfeiting labels. Through this explanation, we know that radio frequency identification is not specially developed for the anti-counterfeiting industry, but it makes the idea of ​​anti-counterfeiting laser labels a reality and solves many problems in anti-counterfeiting technology. Applying this technology to the label can make the chip of the label have unique identification. Only the same identification code can match. This technology may be a disadvantage if it is applied to other industries, but it is applied to laser anti-counterfeiting labels. Perfect existence. The application of radio frequency identification system in the label has brought the anti-counterfeiting technology to a higher level. It is hoped that this technology can be further improved to make the anti-counterfeiting performance of the laser anti-counterfeiting label better.
