Abstract: The dual-frequency RFID technology was originally created by EM and was originally developed based on customer needs.
As far as RFID technology is concerned, UHF RFID has a long recognition distance, up to 10m or more, and has a fast recognition rate. It can automatically collect characteristic data such as object number, attribute, and status, and has strong applicability in the digital management of personnel, assets, and items; NFC can recognize and transmit data at close range, with an effective recognition distance of about 10 cm, and supports two-way connections. It can create a high encryption and high security environment for data interaction between devices, and has unlimited potential for anti-counterfeiting.
When the two break the technical barriers and combine together, what kind of innovation can it bring to the RFID industry? As a wholly-owned subsidiary of the Swiss watch Swatch Group, EM Microelectronic has recently launched the latest generation of dual technology that meets the dual technical standards of RAIN and NFC. The frequency chip em|echo-V (EM4425), which integrates the different characteristics of UHF and HF on a single chip, greatly expands the application scenarios of RFID technology, increases the added value of RFID technology, and has been used in alcohol anti-counterfeiting, There are mature applications in the fields of smart packaging, medicine, retail and e-commerce.
Advantages of dual-frequency RFID technology
What are the advantages of dual-frequency RFID technology compared to single-frequency RFID technology? Simply put, dual-frequency has more possibilities. Without considering the cost, the functions that a single high-frequency technology or a single UHF technology can achieve are far less rich and convenient than dual-frequency technology. It is understood that Wuliangye used UHF RFID technology to prevent counterfeiting and channeling goods before. UHF technology can facilitate the intelligent management of distributors in logistics and warehousing, but it is not conducive to the anti-counterfeiting identification of end consumers, because consumers have no corresponding inquiries For equipment, it is difficult for end consumers to check the authenticity of goods through UHF.
After the introduction of high frequency, consumers only need to use a smart phone that supports NFC to realize the authenticity of the product. This is Wuliangye’s upgraded anti-counterfeiting technology-the world’s first dual-frequency anti-counterfeiting label. “One core dual frequency”, one core win-win, not only convenient for consumers, but also beneficial to dealers.
The dual-frequency RFID technology was originally created by EM and was originally developed based on customer needs. In the past, high-frequency solutions could trace the source, prevent counterfeiting and verify authenticity, and also support friendly interaction between consumers and merchants. Later, customer needs changed, and UHF was used to prevent stray goods. In the case where UHF read heads are more expensive, the dual-frequency chip developed by EM has 2 KBit shared memory, which is not limited by the read head, and both UHF and high frequency read heads are compatible. That is, the user can complete the tag reading operation only with his own smart phone.
Dual-frequency RFID chip EM4425 upgraded version function
EM’s newly developed EM4425 dual-frequency chip has been updated and upgraded in terms of performance indicators. It has AES-128 encryption algorithm and supports tamper-proof function. The NFC part is compatible with ISO/IEC 15693 and ISO/IEC 18000-3 protocols. Compared with the original 14443 protocol, it can support the reading distance of smart phones. Improve the consumer experience. The unique high encryption feature of EM4425 makes it possible for consumers to conduct anti-counterfeiting inquiries through Apple mobile phones. In addition, in the era of APP proliferation, its unique WEB security certification allows consumers to directly jump to the web page for anti-counterfeiting query and verification without installing APP.
EM4425 has an independent open circuit detection function. The label equipped with the chip is directly integrated into the product package. Once the package is opened, the open circuit is destroyed. Regardless of whether it is read by high-frequency or ultra-high frequency (or NFC mobile phone), the chip is directly invalidated and cannot be reused. It can also be used to detect whether the product package has been opened.
The function of the upgraded version of EM4425 is temporarily unable to be realized by other dual-frequency RFID technical solutions on the market, which is also one of the important reasons for EM to occupy an important share in the market. Although some RFID technology applications on the market can use both dual-frequency and single-frequency technical solutions, because the dual-frequency chip itself is large in size and expensive, customers generally choose the best according to the cost and the actual effect of the implementation of the solution. Technical solutions.
Dual-frequency RFID is a general direction for future RFID industry applications
At present, the most successful application of dual-frequency RFID technology is wine anti-counterfeiting, such as Wuliangye, Moutai, and French brandy brand Remy Martin. In 2015, Remy Martin has applied RFID technology to wine bottles. Consumers can get information such as Remy Martin reward points, discounts and other information on wine bottles with NFC-enabled smartphones, as well as information on the certification of origin of the wine. . Once the consumer opens the wine bottle package, the tag antenna breaks and sends out a signal, indicating that the wine bottle changes from a closed state to an open state.
In addition, dual-frequency RFID technology has mature applications in the field of smart packaging. For example, technology company eAgile integrates EM’s dual-frequency chip into its own RFID smart packaging solution, and innovatively embeds RFID tags on the packaging bottle caps for smart packaging of non-prescription drugs, nutritional food, cosmetics and chemicals. It guarantees the expiration date of medicines, the freshness of food, the integrity of cosmetic packaging, and the safety of chemicals, and provides item-level visibility in the complete supply chain from manufacturing to transportation to retail shelves to consumers.
Dual-frequency RFID technology has also been applied in the field of e-commerce. The purpose of dual-frequency technology deployment in the e-commerce field includes all the benefits of RFID technology applied to the retail industry, such as: safer brand protection, more innovative digital experience, more intuitive consumer interaction, more efficient logistics supply chain, Smarter inventory management, more convenient ordering methods, and more revenue.
According to EM’s prediction, dual-frequency RFID technology is a major direction of the RFID industry. As the cost drops in the future, dual-frequency RFID will expand to more application scenarios. The application market has also been expecting technological advancements to unearth more functions of RFID, and the emergence of RFID dual-frequency technology extends the value chain of RFID on the original basis, and also represents a milestone development for the entire industry.
