I’d like to develop a tool, in which you scan with a smartphone a QR-Code of a product, which contains information like what kind of product is this and the tool sends the information and information such as the date, time, location and from whom it was scanned to blockchain or smart contract where it gets stored and benefit from the blockchain technology such as immutable and backtracking of data. So you can see it as a product tracking which the information is stored in a blockchain.
