Problem Statement

In moments of medical emergency or high emotion, every second counts. People need instant access to health information or personal content—without logging in, searching apps, or scanning QR codes.
The challenge was to design a seamless, tap-and-view experience for NFC tags that connect users instantly to:

• Medical Emergency Details

• Quick-Access Photos

• Surprise Birthday Cards

All with zero to one click.

Goals

• Eliminate friction in critical and joyful moments—access should feel magical, fast, and intuitive

• Support three key use cases:

  1. Emergency medical info for first responders

  2. Personal photo sharing via tap

  3. Surprise birthday cards with interaction

UX Approach & Strategy

1. User Research & Needs Discovery

• Interviewed 5 users (2 emergency responders, 3 everyday users)

• Key insights:

  1. “We don’t have time to click around in an emergency.”

  2. “Tapping and seeing something right away feels futuristic and personal.”

• Need for touchless, instant, and clear content delivery

2. UX Principles Applied
✅ Zero Friction: Open content without login or extra steps
✅ NFC-First Mentality: Designed for tap-to-open behavior
✅ Clear Hierarchy: Large CTA buttons, readable typography, high contrast
✅ Micro-Delight: Personalized messages, auto-play video/photo cards, and a joyful user flow for birthday surprise mode

Design Process

1. Information Architecture

• Created 3 content branches:

  1. Medical – Emergency info, allergies, blood group, ICE contact

  2. Photo/Video Share – Lightweight media preview

  3. Birthday Surprise – Confetti animation + hidden message reveal

2. Wireframing (Low & Mid-Fidelity)

• Designed single-screen flows with contextual auto-reveal:

  1. Tapping shows the most relevant block based on time/user-type

  2. Used collapsible cards to minimize noise

3. UI Design

• Clean, minimal, calming UI (whites + accent green/blue)

• Icons for quick scanning ( for medical, for birthday, for media)

• Designed responsive layouts that work instantly on mobile browsers

4. Prototype & Testing

• Tested tap → browser journey on 4 Android + 3 iOS devices

• The feedback loop helped improve loading feedback and reduce text density

Outcome & Results

• Achieved < 2-second average access time after NFC tap

• Users accessed content in 0–1 clicks across all use cases

• Birthday card version got high emotional responses and re-tap engagement

• Created a scalable design system for future NFC-tagged moments (e.g., events, promos)

Key Learnings

• UX for hardware-integrated web tools is about simplicity and clarity

• Emergency scenarios require fail-proof flows, no distractions

• Joyful moments like birthdays benefit from micro-interactions and visual flair

• Minimalism = magic when backed by real-time tech like NFC
