MIT develops an unclonable micro tag for crop seeds to fight counterfeiting

Average crop yields in Africa are consistently far below those expected, and one significant reason is the prevalence of counterfeit seeds whose germination rates are far lower than those of the genuine ones. There have been many attempts to prevent this counterfeiting through tracking labels, but none have proved effective.

Now a team of MIT researchers has come up with a tiny, biodegradable tag that can be applied directly to the seeds themselves, providing a unique, randomly created code that cannot be duplicated, they claim...
