Asia-Teco Smart NFC Ring (Model SR01-NFC) — Your All-Day Wellness & Smart Access Companion

Meet the Asia-Teco Smart NFC Ring — a sleek black ceramic ring that seamlessly blends sophisticated jewellery design with cutting-edge wearable technology. Weighing just 4 grams, you'll barely notice it on your finger, yet it works around the clock tracking your body's key signals, managing your active lifestyle, and making daily life more convenient with one-touch NFC access.

Crafted for Everyday Elegance

The ring is constructed from premium black ceramic — a material prized for its mirror-smooth finish, scratch resistance, and exceptional durability. Its low-key matte lustre highlights understated style while the ergonomic curvature fits snugly against your finger. Whether you're heading to the office or hitting the trail, this ring looks as good as it performs.

Comprehensive Wellness Monitoring

Powered by a multi-sensor fusion system and 3D integrated sensing center, the ring continuously captures a broad range of physiological data:

• Heart Rate & Blood Oxygen: Static heart rate detection accuracy of over 95%, with real-time blood oxygen readings and historical data review via the companion app.
• Blood Glucose & Blood Pressure Trend Tracking: Dynamic monitoring technology provides ongoing trend insights so you can stay informed about changes over time.
• Full-Cycle Sleep Tracking: Automatically identifies deep sleep, light sleep, and wakefulness periods, generating visual sleep reports to help you refine your nightly routine.
• Temperature & Stress Analysis: Continuously records body temperature curves and evaluates stress levels via heart rate variability — with timely alerts for emotional fluctuations.
• Women's Wellness Management: Intelligent prediction of menstrual and ovulation cycles for effortless physiological cycle awareness — no manual logging required.

The built-in NFC module lets you unlock access control systems, elevators, and parking gates with a simple lift of your finger. Say goodbye to fumbling with physical key cards — your ring is your key.
