Until now there hasn’t been an efficient and convenient way to check drugs to make sure they are the real deal. However, a Hawaiian company called TruTag Technologies has discovered a way to add edible bar codes to foods and drugs, allowing manufacturers to put an unique identifier in their products, one that will register when scanned, Bloomberg notes.
The edible bar codes are created by etching the codes on to silicon wafers that are then crushed into powder. The superfine power can be added to foods or incorporated into pill coatings. The process works just as well with non-consumable products.
TruTags was recognized by the World Economic Forum with the 2014 Technology Pioneer award. It has received seed money from venture capitalists and the Pentagon.
Scanners that can detect the edible bar codes could even find their way into smartphones eventually, allowing consumers to check their medication or food to make sure it is what they expect.
