The Challenge
Paper business cards are easy to lose and impossible to update. The goal was a frictionless way to share rich, up-to-date contact details in person or remotely, while letting one person keep separate cards for different contexts — work, side projects, social.
The Solution
NTWKD gives each user up to five distinct cards, each generating a scannable QR code that opens the card instantly. Cards support photos, social links, and website integration, and can export straight into the phone's native contacts. Subscriptions and secure payments are handled in-app, with Firebase backing auth and data and Method Channels bridging to native platform features.
