Cracking the Global Supply Chain Code with A.I. and DNA.

Companies and government officials are turning to advanced technologies like DNA tracking, artificial intelligence, and blockchains to trace raw materials from the source to the store amid growing concern about opacity and abuses in global supply chains. The international supply chains that companies have built in recent decades have grown astonishingly complex, making it difficult to trace products. Some companies are using scientific processes to tag or test a physical attribute of the good itself, while others are turning to digital technology to map supply chains. Having a full picture of their supply chains can offer companies other benefits, like helping them recall faulty products or reduce costs.
