THE CHALLENGE
OUR SOLUTION
THE RESULT
Challenges We Faced
Our first attempt used Flutter’s AR libraries. We quickly realized that they lacked advanced features and performance for complex AR interactions.
We then moved to ARCore (Android) and ARKit (iOS). While powerful, managing two separate native codebases increased complexity and slowed progress.
Finally, we integrated Unity for AR development and connected it with Flutter for the app’s main framework. This gave us robust AR performance with the flexibility of Flutter’s UI.
Rendering AR experiences required balancing smooth performance with device limitations. Optimizing memory usage and frame rates was a key technical challenge.
Ensuring that AR behaved the same way across different devices and operating systems demanded constant testing and fine-tuning.
Advanced stack behind smarter sales outreach
The project evolved from a simple authentication requirement into a connected physical-digital experience. The development journey focused on making NFC authentication intuitive while establishing the digital identity, blockchain, and AR capabilities required to extend the value of physical collectibles.
Phase 1: Understanding the Authentication Model
We defined the core requirements around collectible authentication, NFC interaction, unique identifiers, blockchain-based digital identity, and the overall collector experience.
Phase 2: Designing the Mobile Experience
The user journey focused on a simple NFC interaction, allowing collectors to begin authentication without navigating a complicated verification process.
Phase 3: Building the Flutter Application
The mobile application was developed using Flutter to provide a consistent cross-platform experience while integrating the core authentication functionality.
Phase 4: NFC & Blockchain Integration
NFC functionality was connected with unique collectible identifiers, creating the link between the physical item and its corresponding digital identity on the blockchain.
Phase 5: AR Experience Integration
The platform was extended with augmented reality capabilities, including surface detection and 3D content, allowing authenticated physical assets to become part of interactive digital experiences.
Phase 6: Testing & Refinement
The major authentication, NFC, digital identity, and AR user journeys were tested and refined to create a smoother and more reliable experience.
Measurable Outcomes After Launch
Users can begin the collectible authentication process by tapping an NFC-enabled mobile device against the physical item.
Each NFC tag contains a unique identifier linked to the corresponding item's digital identity on the blockchain.
The platform supports AR-based experiences with surface detection and 3D models connected to physical assets.
The public App Store listing documents AR video recording of up to 90 seconds along with capture and sharing functionality.
Week Discovery & Requirements
We identified the core requirements around NFC-based authentication, collectible identity, blockchain records, physical-digital connectivity, and the overall mobile experience.
Week UX/UI Design
The experience was planned around a simple NFC interaction so collectors could begin authentication with minimal steps while keeping important digital information accessible.
Week Flutter Development
The application was developed using Flutter to create a consistent mobile experience while integrating NFC and the core collectible authentication functionality.
Week Blockchain Integration
Unique identifiers stored within NFC tags were connected with corresponding digital identities on the blockchain, creating a foundation for collectible authentication and transparent records.
Week AR Integration
Integrated augmented reality capabilities using Unity and AR Foundation, including surface detection and 3D models, to create interactive experiences around physical assets.
Week Testing & Refinement
Tested the core NFC authentication flow, digital identity connection, AR experiences, and mobile interactions to improve reliability and usability.

SaturnCube is an outstanding company. Many developers approached me, and “warned” me, that working with offshore companies is difficult. And yes, it is! But this is no reason not to do it. Having your project team & developer not sitting beside you, is a challenge. As you have to have more trust that they do the things right in your absence. Projects never run “smooth”, (otherwise it would be routine tasks and not projects) – and what I like at SC, is, that if there are problems, from scoping, financially or else, you will always find a solution.
