The fraudulent products are detected using a camera scanner, and the QR or barcode of the item or items is connected to a blockchain to save the item's information and the guaranteed unique code, which are stored as database blocks. Given the huge upward developments in wireless technology, this initiative uses barcodes and QR (Quick Response) codes as a way to limit the practise of product counterfeiting. The fraudulent products are identified using a camera scanner, and the QR or barcode of the product or products is connected to a blockchain to store the product's details and the guaranteed unique code, which are kept as database blocks.

Block chain, smart contracts, QR(Quick Response) code, anti- counterfeit.
