QRcard started from a simple problem: paper business cards get lost, and sharing digital contact details is often clunky. The app turns your details into a QR code any camera can read — no internet connection needed.

Built and actively maintained by Lukas Hechenberger, QRcard is the product we use as a testing ground for what we recommend to clients building their own apps: native iOS and Android development, real offline capability, and a feature set that stays deliberately lean.

The free version covers up to 3 contact details per card; a one-time in-app purchase unlocks unlimited details and removes the "Created with QRcard" note. For companies rolling out digital business cards across their whole team, there's also the standalone QRcard Enterprise Edition with full Mobile Device Management (MDM) support.

Features

  • Share contact details instantly via QR code — even offline
  • Custom design with your own colours and logo
  • Home and lock screen widgets, including a personal #QRlockscreen wallpaper
  • Up to 6 QRcard personas to separate business from personal contacts
  • Supports title, company, department, phone, email, address, and social profiles (LinkedIn, Instagram, GitHub, and more)
  • All data stays on-device — nothing is uploaded or stored on a server

Technical Details

  • Native iOS and Android apps, not a cross-platform wrapper
  • Offline-first — core functionality needs no internet connection
  • Local-only data storage, no server backend, no cloud sync
  • iOS and Android home- and lock-screen widgets
  • Localized UI: German and English

“I don't know my German phone number so I love having this app because I can quickly meet people and share contact information without being slowed down! Get it now ;)”
