How to get out of the four major misunderstandings of RFID tags

RFID technology is one of the current hot topics, such as the labels used by smart packaging airports or libraries used in the pharmaceutical industry, and the labels used in logistics and supply chain, etc., have already been or are preparing to adopt RFID technology. What does this growing new thing mean for a label printing company? There is no doubt that RFID labels bring new opportunities for label printing companies, but there are still some misunderstandings in the RFID industry. Label printing companies How to correctly understand and get involved in RFID technology? This article will tell you the answer.

RFID tag production

The following briefly describes some of the actual situation in the production of RFID tags. After the RFID chips are produced and transported as semiconductor wafers, these chips are sent to embedded processors where they are processed to make the chips meet the technical requirements for label embedding. The chip will be connected via an integrated circuit and an antenna. This automatic pick and place process is performed by the robot in an absolutely dust-free environment. The inline completion marks the end of the preparation of the RFID core component. The label printing company can then sandwich the inlay in the middle of the label substrate like a sandwich, so that a complete RFID tag is completed.

Each chip has a certain amount of storage space. At the beginning, no data is written until the embedded and substrate composites are produced. Label printing companies or end users can write relevant information into the chip. Since the automatic pick-and-place process is required to be completed in an absolutely dust-free working environment, the embedded processing is quite difficult for the label printing company. Of course, if there is no guarantee of a dust-free working environment, it can also be done by printing an antenna: A ribbon-shaped connecting pad is mounted on an on-line production line for printing of the antenna. Industry experts think. Printed antennas are a promising technology.

The design and fabrication of the antenna can be done by etching the copper wire, or it can be printed with conductive ink. In order to improve the performance of the antenna and reduce the impact of metal or liquid products on the tag reading rate, some major RFID manufacturers have standardized the antenna design. It is speculated that printing an antenna with conductive inks will be a very important way to reduce the cost of RFID tags, but it may take several years for the technology to mature.

There are several major challenges in producing high-quality RFID tags. Some problems existed even before the tags began to be produced (most notably the chip problem). The label printing companies believe that there are two main problems in the production phase of RFID tags. : Problems with electrostatic problems and label testing.

Misunderstandings in the RFID industry

There are many arguments about RFID, and it is sometimes difficult to tell whether it is genuine or not. Listed below are some common misunderstandings in the industry. Let us analyze them together.

Misunderstanding 1: The quality of the RFlD tag is very poor

About two years ago, the pass rate of RFID tags was almost 50%. This figure scares off many label printing companies. Although there are still 20% of non-conformance rates for RFID tags, experts from Avery Dennison believe that the quality of RFID tags is indeed improving and improving. We should be more patient with them. At present, the various types of universal labels we use have reached the current level after many years of development. It takes a certain amount of time for RFID labels to get people's approval. Moreover, due to the addition of chips, making RFID tags a rather sophisticated and complex communication device, it is not realistic to expect RFID tags to achieve very high application performance at once.

Although RFID is not a new technology, it is still used for the first time on many occasions, and it takes a certain amount of time to write operating instructions, so it is not surprising that it takes months or even years. Using UHF RFID tags in the supply chain is only the last two to four years.

Myth #2: Wal-Mart's Greatest Contribution

When Wal-Mart asked its suppliers to adopt RFID technology at the end of 2003, everyone believed that the top 100 suppliers would certainly do their best to meet the requirements of the retail giant. Although more than 100 suppliers have adopted RFID technology, The pace and magnitude are not as fast as people expected. These suppliers certainly attach great importance to Wal-Mart's requirements, but they adopted a more conservative and cautious approach in their operations, waiting for the progress and maturity of the technology, as well as the introduction of new EPC standards.
