Case Study: Qardl achieves seamless QR code networking with Tinderhouse

Qardl launches cross-platform digital business card app in 2025 with Tinderhouse

Qardl, a digital business card platform, approached Tinderhouse with the challenge of transforming professional networking by digitizing the exchange of contact details. They needed to create a seamless sharing experience that worked for both app users and non-users, build a robust QR code system for busy events, and implement a scalable backend with dual subscription management for iOS and Android.

Tinderhouse developed a cross-platform mobile application using a hybrid approach with Framework7, delivering native-like performance on both operating systems. Their solution included a sophisticated QR code generator, a RESTful API integrated with ExpressionEngine CMS, and secure subscription systems. The results were a successful 2025 launch on both app stores, a scalable platform handling multiple user profiles, and the delivery of intuitive, offline-capable QR sharing. Tinderhouse built a flexible foundation for Qardl's future growth and feature development.
