One Stop Halal is an app that can help identify the halal and non-halal products based on the product barcode. The user can scan the product barcode with their smartphone and the app checks the product from an online database. The app displays the product details and the halal status of the product. Users can consume the product with confidence after verifying it with the app. The app will store a history of scanned barcodes for product barcodes that were not available in our database.
