Backed by10+ certifications, patents, and design awards, REINK has built an ironclad IP moat in color e‑paper — turning deep tech into your competitive edge.

Software Engineering — Native, Cross-Platform, Enterprise-Ready

We build apps that perform flawlessly across every ecosystem your customers inhabit, while cutting development timelines and maintenance costs.

  • HarmonyOS Native Development
    As a first-wave HarmonyOS ecosystem developer, we unlock the full performance potential of the platform, delivering fluid, native applications that leverage every system-level advantage.
  • Android Native Development
    Years of Android engineering across multiple successful apps have given us battle-tested expertise in stability and security — ensuring reliable operation even under the most complex, real-world scenarios.
  • iOS Native Development
    We follow Apple’s design and development guidelines meticulously, crafting visually refined, highly responsive apps that meet the premium expectations of iOS users.
  • Flutter Cross-Platform Development
    Our deep Flutter proficiency enables a single codebase to generate high-quality apps for both platforms simultaneously, dramatically reducing long-term maintenance costs and accelerating time-to-market.

Hardware Engineering — Battery-Free, Wireless, and Mass-Production-Ready

Our hardware innovations are engineered to eliminate end-user friction while streamlining your supply chain and reducing after-sales complexity.

  • NFC Powerless Energy Harvesting
    Devices draw energy directly from the NFC field — no internal battery required. This slashes weight, eliminates leakage or overheating risks, and delivers an instant “tap-and-use” experience. From the ground up, it’s a greener, safer design that drives down warranty claims.
  • Bluetooth Connectivity with Apple Find My
    Our trackers integrate BLE and Apple’s Find My network. Nearby, precise location is at your fingertips; far away, the global Apple network keeps tabs on your item — even when offline. A high-perceived-value feature that builds brand loyalty.
  • Wi-Fi Image Transfer
    High-performance Wi-Fi modules in our e-paper frames connect straight to home networks. Users update photos remotely from their phone — as easily as sending a message — eliminating the hassle of cables and SD cards for good.
  • SparkLink Readiness
    We are proactively integrating SparkLink’s ultra-low latency, high-reliability short-range communication, reserving ample headroom for next-generation multi-device collaboration and high-performance interactive experiences.
  • Reverse Wireless Charging
    By drawing power directly from a smartphone’s battery, we preserve the “zero-battery” design philosophy — thin, safe, and eco-friendly — while overcoming the inherent energy limitations of NFC harvesting. This breakthrough opens the door to richer features and a wider variety of smart product forms.
  • NFC/RFID Mass Production Testing
    For high-volume e-paper module production, we deploy efficient NFC/RFID readers to bulk-initialize, flash firmware, and self-test battery-less screens on the line. The result: faster throughput, tighter quality control, and a consistently rigorous standard across every unit shipped.

Manufacturing & Delivery — Scalable, Automated, and Supply-Chain-Secure

We’ve built an intelligent production matrix where high-precision automation drives everything from module assembly through to finished-product testing — fully automated, fully traceable.

Our supply chain is forged through long-term strategic partnerships with industry leaders: E Ink (Yuantai), REFOND, SEEKINK, HIPOINK in e-paper displays, and FUDAN MICRO, FEITIAN in chipset supply. This is further strengthened by our own wholly-owned factory.

The result is a dual advantage — core supply chain ownership + in-house manufacturing — that dramatically boosts output speed, locks in capacity stability, and guarantees on-time delivery. For our partners, that means one thing: rock-solid supply assurance, at scale.
