Project Description: I need a website similar in design and functionality to sunandaglobal.com with an additional QR code-based reward system for my product packaging. When a customer scans the QR code printed on our product cap, they should be redirected to our website and see a popup with a unique coupon code (the code will be the same as printed below the QR). After clicking "Submit", the customer should be asked to enter their UPI ID. Once submitted, I will manually send the reward payment to that UPI ID. Each unique code should work only once — once a code is redeemed, it should show “Code already used” if scanned again. Main Requirements: Website Design: Similar layout, pages, and look as sunandaglobal.com . Mobile-friendly, clean UI/UX. QR Code System: Each product will have a unique QR code printed on it. The QR will link to https://mywebsite.com/scan?code=UNIQUECODE. When scanned, the website should automatically: Detect the code. Open a popup showing: The unique code. A short text like “Congratulations! You’ve unlocked a reward.” An input box for UPI ID. A “Submit” button. Reward Submission Logic: Once the customer enters their UPI and clicks submit: The code is marked as used (one-time only). The UPI ID and timestamp are stored in the database. A confirmation message is shown. If the same code is scanned again, show “This code has already been used.” Admin Panel (optional but preferred): Login for admin. View all redeemed codes, UPI IDs, and timestamps. Export data (CSV/Excel). QR Generation: A script or admin tool to generate QR codes with unique codes that redirect to the scan URL. Export QR codes for printing (PNG or PDF). Deliverables: Full responsive website (frontend + backend). QR code generation script. Database setup for code validation and redemption tracking. Simple admin dashboard (if included). Deployment assistance (optional). Notes: This system will be used for promotional campaigns — reliability and clean UI are important. Only one-time code redemption should be ensured.
