The E-Commerce App with QR-Based Checkout is an innovative mobile/web platform that enhances the shopping experience by combining traditional online shopping features with fast, secure, and contactless payment through QR code technology. This solution is ideal for both online and in-store retail environments, allowing customers to shop and check out efficiently using QR codes.

Users can browse products, add items to their cart, and proceed to a unique QR-based checkout process. At checkout, the app generates a dynamic QR code containing order details and payment information.
