I need a straightforward, browser-based application that lets anyone scan a product’s QR code—or manually type its serial number—and immediately see whether the item is genuine. No sign-ups, logins, or personal data: the verification flow must remain completely anonymous so customers can check authenticity in seconds straight from any modern web browser. On the back end I’ll upload and manage the master list of valid serials. When a code is queried, the system should match it against that list, return a clear “Authentic / Not Found / Already Verified” message, and record basic lookup analytics (timestamp, location by IP, and repeat-check flag) so I can track fraud attempts without storing user identities. Key needs • Responsive web interface optimised for both desktop and mobile browsers • QR scanner that works natively in-browser (JavaScript/WebRTC) plus a fallback text box for manual serial entry • Secure admin dashboard to import, edit, or retire serial numbers (CSV upload is fine) and to view verification logs • Clean, lightweight tech stack—Laravel, Node, Django, or similar MVC framework is acceptable as long as code is well-documented • RESTful endpoints so the verification logic can be reused later in a mobile app if required • Deployment to my cloud account (AWS, DigitalOcean, or comparable) with HTTPS enabled Acceptance criteria 1. A visitor can scan or enter a code and receive an authenticity result in under two seconds. 2. Admin can upload at least 100k serials and search logs without timeouts. 3. All sensitive routes are behind authentication; public verification never requests personal data. 4. Source code, database schema, and a concise README are delivered at handover. If you’ve built ticket or warranty validation tools before, your expertise will be a plus. Let me know your preferred stack and estimated timeline, and include a live example or repo if possible.
