Fix QR Scanner & Transaction Status Bug in React Native Token App

@gtssoftindia

Banana Hi Mate, I came across your project CareCredits and I like the concept of simplifying discount coupons, access passes, and reward credits in a mobile app. I’ve previously fixed QR scanning and live update issues in React Native apps, so I understand the technical challenges you’re facing. Here’s how I can support your app: 1. Debug and implement a reliable QR code scanner (React Native Camera / Expo Camera). 2. Add live transaction status updates using polling or WebSocket. 3. Clean the UI by removing all financial/crypto elements to highlight non-financial tokens. 4. Ensure smooth user experience focused on discount and access tokens only. Quick questions: 1. Do you already have the backend endpoints for transaction updates or should I help define them? 2. Are you planning to extend CareCredits with new features after this MVP fix? This assignment looks feasible to complete in 2–3 days. I’ve provided a ballpark estimate, and we can finalize once I review the codebase. Let’s make CareCredits user-friendly, clear, and solid. Best regards, Tejas J

My expertise in React Native development, specifically handling barcode scanning and API integrations within tokenized systems, makes me the ideal candidate. I recently resolved a similar critical bug in a decentralized identity app, leveraging ZXing and Firebase for efficient QR code processing and real-time status updates. This involved rigorous testing and optimization to maintain app performance and security. My approach involves a three-step process: 1) Thoroughly debugging the existing QR scanner implementation within your React Native app, utilizing debugging tools like React Native Debugger and examining the relevant codebase sections. 2) Implementing robust error handling and potentially replacing the current QR scanning library with a more efficient alternative like ZXing or similar if needed, focusing on improving performance and reliability. 3) Integrating a reliable backend solution for seamless transaction status updates, focusing on efficient API calls and data management, and implementing thorough testing to ensure accurate real-time status display. Let’s discuss this further! Could you provide details about the current QR scanning library and the API you're using for transaction status updates, so I can tailor my approach for optimal results and a swift resolution?

Hi Bohdan, I’ve developed multiple apps with QR scanning features using both Expo and custom React Native camera solutions. I can quickly identify and resolve the underlying issues affecting your QR scanner. For real-time updates, I’ve successfully implemented WebSocket and polling solutions in previous projects, ensuring users receive timely notifications without needing to refresh. As a React Native developer with 5 years of experience, I’ve worked extensively with both Expo and bare React Native. I’m also a full-stack developer, so I can handle any backend tasks if needed. Let’s schedule a 10-minute introductory call to discuss your project in more detail and see if I’m the right fit. Feel free to message me anytime—I usually respond within 10 minutes. I’m eager to learn more about your exciting project. Best, Adil

Banana Hi there! I understand you're facing issues with the QR code scanner and transaction status updates in your CareCredits app, and you also need to remove financial/crypto references from the UI. I’ve worked on similar projects involving React Native, where I’ve resolved QR scanning issues and implemented live transaction updates, so I’m confident I can help you with this. In a recent project, I fixed a QR scanner issue in a React Native app by using the React Native Camera, ensuring it accurately scanned both printed and digital QR codes. I also implemented real-time transaction updates using WebSockets, allowing users to see the status change instantly, just as you require. The client was very pleased with how the issues were quickly resolved, and the app was successfully deployed. For your project, I’ll debug the QR code scanner using React Native Camera or Expo Camera, ensure the transaction status updates in real-time, and remove any financial references from the UI to make it clean and focused on token usage. I’ll ensure everything works smoothly within 2-3 days and deliver the fixes you need. If you choose me, I’ll get this done quickly and efficiently. Even if you decide to go with someone else, I hope you find the right developer to resolve the issues. Good luck!

@kreativesol

Hey there, Good day! Do you want the QR scanner to support both front and back cameras, or just the default camera? Also, should transaction updates be real-time via WebSockets or is periodic polling sufficient? I’ve worked on React Native apps fixing QR scanning issues and implementing live status updates—samples can be provided upon request. Here’s what I suggest for your project: QR Scanner Fix: Use React Native Camera or Expo Camera to reliably scan printed and on-screen QR codes. Transaction Status Updates: Implement live updates via WebSocket or polling so UI reflects pending → success/failure automatically. UI Cleanup: Remove all financial/crypto references, ensuring the app clearly focuses on discount and access tokens. Deliverables: Fully functional QR scanner, live transaction updates, and clean UI ready for deployment. Thanks and Regards, Abdul Basit Kreative Solutions
