What is RFID tag ink, what is RFID electronic tag

RFID tags are recognized as smart tags in the real sense, and they are the crystallization of high-tech such as electronics in label printing.

The antenna is an important basic element of RFID tags. At present, the manufacturing methods of RFID tag antennas include etching, electroplating and direct printing. Due to the complex process of etching and electroplating, the production cycle is long, a large amount of metal is consumed, solvent waste is generated, and the environment is polluted, so the direct printing method has obvious advantages in making RFID antennas.

According to the printing method of the antenna, the corresponding ink products were developed.

Conductive silver paste can be printed by screen printing and gravure printing processes. Silver-solid content, viscosity, sintering temperature, and resistivity are the first parameters to consider when selecting a conductive silver paste. Viscosity determines its printability; Silver-solid content and resistivity are important indicators to consider the conductivity of the printed RFID tag antenna. The sintering temperature indicates how much energy is required to cure.

Inkjet printing is a method of making RFID tag antennas that has recently attracted everyone's attention. The conductive inks used in this method are inkjet conductive inks. Inkjet conductive inks are mainly composed of metal particles, solvents, binders, additives and other components.

Among the metal particles, the most widely used is nano silver, because the ** of silver is relatively low, excellent conductivity, good ductility, not easy to be oxidized (silver oxide can also conduct electricity), and the sintering temperature of nano silver is low, which can meet the application requirements of RFID tag antennas on non-high-temperature substrates. The solvent of inkjet conductive ink is mainly water, and alcohols such as ethanol, n-propanol, and isopropanol can be added to it to adjust the drying speed and surface tension of the ink. The binder is the main film-forming substance of inkjet conductive ink, which can improve the adhesion fastness, friction resistance and waterproof property of the ink on the surface of non-absorbent substrates.

Additives are generally used to adjust the viscosity, pH value, conductivity, surface tension and other characteristics of inkjet conductive inks, and are indispensable components in inkjet conductive inks.

RFID tag antenna printing is also a kind of electronic circuit printing, and the production process has strict printing requirements. First of all, the amount of ink used must be accurate; Secondly, there should be no deviation in the printing position, the resolution should be appropriate, and the cost and the characteristics of the process should be considered in the whole process. In the future, if the printed RFID tag antenna is as simple and controllable as the printed newspaper, then the RFID tag will enter a new era.

RFID tag is an electronic tag. You can understand that a product similar to the access control card is a low-profile version of the access control ID card.

Each electronic tag has an ID code, which has the same function as the bar code, but the difference is that it can be passively sensed without active scanning.

This kind of RFID tag is already being applied in many places in life. For example, in Decathlon supermarkets, each product has an electronic tag that is attached to an inconspicuous place where the product is attached, such as sneakers under the insole. When settling the goods, you can feel it, and when you go out of the security door, the electronic tag will not be alarmed if it has been settled.

For another example, there is also this RFID tag on the filter element of the Xiaomi air purifier, and if it is not a filter element certified by Xiaomi, the purifier will not work.

Electronic tag is a kind of data carrier, which can be used to store data, can also be read and written, can be automatically identified, and has the advantages of easy to use, safe and durable.

Spatial (non-contact) coupling of RF signals between the transponder and the reader by means of a coupling element;In the coupling channel, energy transfer and data exchange are realized according to the timing relationship.

RFID electronic tags are also known as radio frequency tags.

Radio Frequency Identification, etc. It is a non-contact automatic recognition and merging technology, which identifies the target object through radio frequency signals and obtains relevant slippery sock data, and the identification work does not require manual intervention, as a barcode.

RFID technology has the advantages of waterproof, anti-magnetic, high-temperature resistance, large reading distance, tag data can be encrypted, large storage data capacity, and storage information can be changed freely. As shown in the picture, there is a detailed introduction of RFID.

The dumplings are very good, I have sold 2 catties, Mr. Zhang is a real person, praised.

RFID printers write information to RFID at the same time

label and at the same time print out the information in the self-adhesive to a printer.

RFID is a kind of radio frequency identification technology, which is a technological innovation applied to barcode labels, and RFID printers are machines that can write RFID into barcode labels and then print RFID labels.

It is a new application field of barcode printers.

For example, at the Shenzhen Hi-Tech Fair last month, I saw Boside's RFID machine, which seems to be the TXR series.

With the development of science and technology, I believe that RFID technology will be more and more widely used If you don't understand, you can learn about RFID first

Junpu electronic tag to RFID electronic tag full explanation as follows:

Radio Frequency Identification (RFID) technology, also known as Radio Frequency Identification, is a communication technology that can identify specific targets through radio signals and read and write relevant data without establishing mechanical or optical contact between the identification system and the specific target.

In the case of radio frequency, it is generally microwave, 1-100GHz, which is suitable for short-range identification communication.

RFID readers are also divided into mobile and fixed, and RFID technology is widely used, such as: library, access control system, food safety traceability, etc.

The radio signal is an electromagnetic field tuned to the radio frequency to transmit data from the tag attached to the object to automatically identify and track the object. Some tags can get energy from the electromagnetic field emitted by the recognizer when they are recognized, and do not require a battery; There are also tags that have their own power and can actively emit radio waves (electromagnetic fields tuned to radio frequencies). The tag contains electronically stored information that can be identified within a few meters.

Unlike barcodes, RF tags do not need to be in the line of sight of the recognizer and can be embedded in the tracked object.

RFID technology is used in many industries. By attaching a tag to a car in production, the factory can track the progress of the car on the production line. The warehouse can track the location of medicines.

RF tags can also be attached to livestock and pets to facilitate positive identification of livestock and pets (positive identification means preventing multiple animals from using the same identity). RFID identification cards can give employees access to locked parts of the building, and RF transponders on cars can be used to collect fees for toll roads and parking lots.

Some RF tags are attached to clothing, personal belongings, or even implanted in the human body. Since this technology may read personal information without the consent of the individual, there is also a risk that this technology will violate the privacy of individuals.
