With the official implementation of the new national standard "Mobile Power Safety Technical Specification" (GB 47372-2026), China's mobile power industry has entered a new era of standardized compliance featuring full-dimension intelligent monitoring and complete lifecycle data traceability. The industry's safety management system has undergone a systemic upgrade. In this industrial transformation, the iTAP contactless tap-to-interact technology — led by Huawei and standardized under the ITMA Smart Terminal Microelectronics Association — has become the core mainstream technology solution for new national standard compliance, thanks to its key advantages in passive offline interaction, high-security encryption, and low-barrier scaled deployment.

Shandong Huayi Microelectronics' independently developed HYM4616 NFC security chip (model: TITP262441T-A) completed full standardized evaluation on February 3, 2026, passing certification based on the iTAP official core standard "IS 22.001 Smart Contactless Proximity Communication Access Layer Test Specification (V0.0.3 Final)." Leveraging its excellent NFC passive near-field communication compatibility, the chip fully supports the iTAP protocol system and was officially listed in the ITMA compliance product directory on May 19, 2026, with certification number iTAPAA0010.

This certification marks a key technological milestone for domestically produced NFC security chips within the iTAP standardization ecosystem, establishing a solid hardware foundation for the industrialization and large-scale commercial deployment of new-standard iTAP contactless interactive power banks.

New National Standard: The Most Stringent Mobile Power Safety Specification to Date

According to authoritative interpretation by the FCA Fast Charge Industry Association, GB 47372-2026 is the most stringent and comprehensive safety specification in China's mobile power sector to date. Building on traditional battery structural safety and electrical safety requirements, the standard adds seven mandatory intelligent management provisions, requiring mobile power products to achieve real-time dynamic monitoring of core parameters including cell voltage, operating temperature, and cycle life. It also mandates data retention for over-voltage, over-current, and other abnormal conditions, complete device information archiving, multi-channel data reading, and high-precision timing verification — systematically addressing long-standing industry pain points such as opaque safety data, inability to trace fault origins, and uncontrollable operating status, while comprehensively raising the safety threshold and intelligence standards for consumer energy storage products.

iTAP: The Optimal Balance of Compliance, Experience, and Cost

To meet the new national standard's compliance upgrade requirements, the industry has formed four mainstream technology pathways: screen display, Bluetooth transmission, USB wired reading, and NFC iTAP contactless interaction. Compared to traditional approaches that suffer from high power consumption, expensive hardware modifications, cumbersome interaction processes, and limited user experience, the iTAP passive tap-to-interact solution — based on a mature RFID/NFC technology architecture and supported by Huawei-led standardized industry ecosystem — achieves the optimal balance of compliance, user experience, and manufacturing economy.

The core technical highlight of this solution is its fully passive, zero-power operation. The chip can autonomously harvest power through RF induction to complete data exchange without drawing from the mobile power's main control power supply. Even when the device is in extreme conditions such as undervoltage shutdown, failure, or inability to boot, users can still bring their phone close to the sensing area to precisely read the device's unique identity ID, cell health status, historical abnormal data, and other core traceability information — fully satisfying the new standard's mandatory requirements for device safety traceability.

Additionally, the solution supports quick identification via phone screen-off popup, requiring no standalone client app and no network pairing, delivering a truly lightweight and seamless intelligent interaction experience.

Huawei-Led Ecosystem and Industry Chain Collaboration

As the core lead organization for the iTAP intelligent interaction ecosystem, Huawei has deeply participated in the top-level design and standardization of the iTAP foundational protocol architecture, access layer test specifications, and security encryption framework, continuously driving the domestic iteration, standardization, and industrialization of contactless near-field interaction technology.

Currently, Huawei's entire lineup of smartphones and wearable devices is fully compatible with the iTAP protocol. Existing devices can receive OTA updates via HarmonyOS to enable screen-off triggering, smart recognition, offline reading, and other core functions, establishing a massive terminal ecosystem foundation for iTAP technology adoption.

Leveraging the ITMA Smart Terminal Microelectronics Association's industry platform, Huawei has coordinated ecosystem participants — including payment platforms, core chip design companies, terminal device manufacturers, and solution R&D institutions — to build a complete industry collaboration chain, continuously optimizing the compatibility, security, and universality of the iTAP protocol and accelerating the scaled commercial deployment of standardized technology.

HYM4616: Benchmark Domestic NFC Chip for iTAP Compliance

On the core hardware side, the Huayi Micro HYM4616 chip — successfully listed in the ITMA official compliance directory — is currently a benchmark domestically produced NFC chip for iTAP new-standard power bank applications. The chip integrates Chinese national cryptographic SM1/SM4 and international dual encryption systems, features tiered access control mechanisms and highly reliable EEPROM tamper-proof storage architecture, and can completely and stably retain full-dimension data including factory parameters, device model, production traceability information, real-time operating status, and abnormal condition records — ensuring stored data is authentic, complete, traceable, tamper-proof, and counterfeit-proof, precisely matching the new standard's compliance requirements of "monitorable, storable, traceable, and verifiable."

Additionally, the chip features large-capacity storage, high RF sensitivity, and ultra-low passive power consumption. Terminal manufacturers can complete compliance adaptation by simply embedding the chip and antenna without modifying the product's exterior structure or main control hardware — effectively reducing hardware modification costs, shortening R&D and certification cycles, and helping terminal companies quickly achieve new-standard compliance certification and bring products to market.

Industry Transformation and Future Outlook

Industry analysis indicates that the comprehensive implementation of the new national standard has fundamentally restructured the competitive logic and industry landscape of the mobile power sector. Industry competition has evolved from traditional metrics of fast-charging power, battery capacity, and cost-performance ratios to a comprehensive, high-quality value competition centered on intelligent safety management, full-chain data traceability, immersive interaction experience, and standardized compliance capabilities.

The iTAP contactless tap technology — backed by Huawei's authoritative standard system, ITMA's official certification, and domestically produced self-controllable chip support — has established itself as the mainstream pathway for industry compliance upgrades. It provides the industry chain with a low-cost, high-efficiency, and highly reliable compliance solution while delivering consumers a visualized, perceivable, and traceable intelligent safety experience, systematically resolving the long-standing safety traceability challenges in the industry.

Looking ahead, Huayi Microelectronics will continue to deepen its focus on NFC near-field interaction and hardware security chip core technologies, continuously iterating and upgrading the HYM4616 product series' performance, protocol compatibility, and scenario-based solutions. The company will continue leveraging the ITMA industry ecosystem platform to deepen collaborative development with Huawei and upstream/downstream industry chain partners, actively participating in the iteration and refinement of the iTAP standard system. With self-controllable domestic chip technology as its core support, Huayi Micro will continue to drive the mobile power industry's standardization, regulation, and intelligent upgrade, building a secure, open, and universally accessible iTAP full-scenario intelligent interaction ecosystem.
