Cardix

Tired of running out of paper business cards, or fumbling to type your contact details into a stranger's phone? Cardix turns your phone into a sleek, professional digital business card that you create once and share instantly — over and over — with a tap, a QR code, or a native contact file. Everything runs 100% locally on your device. No cloud servers, no accounts, and no internet connection required.

HERO INTERACTION

Tap your active card on the home screen to open a glowing QR code instantly. Anyone can scan it with their camera to save your full contact details in seconds, or you can copy the vCard text and paste it anywhere. No app install needed on the other end — just a scan, a save, and a new connection made.

• Instant QR code generation and sharing for any active profile
• One-tap vCard (.vcf) export compatible with every native contacts app
• Built-in camera scanner to read other people's Cardix and vCard QR codes
• Multiple profile carousel to switch your active card in a single tap
• Personalized onboarding quiz that pre-fills a sensible starter profile for your role
• Custom profile photos and company logos for a polished, branded card

HOW IT WORKS

Cardix is built around a simple, repeatable loop for managing your professional identity:

• Complete a short onboarding flow and a 3-question quiz to generate your first profile automatically
• Fill in your name, title, company, photo, logo, and contact details in the profile editor
• Pick an accent color to make your card visually distinct at a glance
• Tap your hero card on the home screen to reveal a shareable QR code
• Scan someone else's Cardix QR code with the built-in camera scanner to preview their details
• Export any profile to a vCard file for permanent storage in your phone's contacts app
• Create additional profiles for different contexts and switch between them from the carousel

Every profile, photo, and contact detail stays on your device, so the app opens instantly and updates in real time — no loading spinners, no network delays, and no waiting around.

PERFECT FOR

• Professionals who want a modern replacement for paper business cards
• Freelancers and consultants juggling multiple personas or client-facing identities
• Salespeople and networkers who meet new contacts at events and conferences
• Developers, creatives, and consultants who want a branded, shareable digital identity

PRIVACY & TRUST

Cardix stores every profile locally on your device using a private on-device database. Your names, titles, companies, photos, contact details, and social links are never transmitted over the network, uploaded to a server, or shared with third parties. There are no accounts to create, no logins required, and no analytics tracking your activity.

You're always in control: create, edit, or delete any profile at any time, choose exactly which details appear on your shared QR code, and switch your active card whenever your context changes. No hidden costs, no subscriptions, and no intrusive permissions beyond the camera needed to scan QR codes. Download Cardix today and carry a professional, shareable business card in your pocket — always ready, always private.
