What is an RFID tag?
As one of the ten most promising technologies in the 21st century, RFID technology will win great market opportunities for the electronic information industry and its suppliers. People in the industry believe that RFID technology is the most promising one among many identification technologies. It is a complete system composed of software design, reading and writing equipment, and labels, which is different from contact identification technologies such as magnetic cards and IC cards.
RFID itself contains a very small tag, which in turn contains a silicon chip and an antenna, and an authorized browsing device can receive the data in the chip. The data stored in the chip can include physical description of the item, such as quantity, style, size and color, as well as information such as origin, shipping and distribution, retail, etc. The identification can be completed without physical contact between the tag and the reader of the RFID system. At the same time, compared with the barcode, RFID not only does not need to be aligned with the target for identification, but also can identify multiple targets at the same time. Automation supervision, and factory assembly line management, etc.
In the process of wireless communication implementation, the antenna is an indispensable component, and RFID uses radio waves to transmit information, and the generation and reception of radio waves need to be realized through the antenna. When the electronic tag enters the working area of the reader antenna, the electronic tag antenna will generate enough induced current to obtain energy to be activated. Due to different materials and manufacturing processes, RFID tag antennas are divided into metal etched antennas, printed antennas, and copper-plated antennas.
Application of aluminum PET film in RFID tags
Aluminum PET film is composed of aluminum foil and PET film. It is mainly used as a circuit substrate in the etching method. After circuit printing and UV curing, etching is performed, ink removal cleaning, circuit conduction processing, and finally coil slitting. Aluminum PET film is the most important material in the etching method.
Advantages of RFID tags
RFID technology has many advantages and has a wide range of application fields. It is mainly used in supply chain management. For example, RFID system is used for goods management in smart warehouses. It can not only process the number of goods, but also supervise all the information of these goods; secondly It can effectively save labor costs, improve work accuracy, ensure product quality, and speed up processing. At the same time, the theft, loss and incorrect quantity of goods containing RFID tags can also be avoided through the reading equipment of the equipment in the logistics center.
In addition, RFID tags can effectively track the dynamics of logistics and retail in the entire logistics and retail process. For example, when goods are delivered to a retail wholesaler or retail store, information is transmitted through scanners above the unloading area, without the need for people to open the box to view the goods. Stores can also monitor inventory levels through scanners installed on the shelves; and when consumers buy the item, they don’t need to queue at the checkout, and the scanner at the exit will automatically identify the item they purchased and display the amount due etc.
