Imagine barcoded crystals so small that they’re edible and considered GRAS by FDA. These “microtags,” produced by TruTag Technologies, Inc., are made of high-purity silica, rendering them biologically inert, edible and nearly invisible—as well as being nearly indestructible and able to withstand very high temperatures.
Each tag can be written with a signature that can only be scanned and decoded by the company’s instrumentation. These microtags can be uniquely coded to indicate a processor, product type, batch number, manufacturing run, plant number, country of origin, etc. Recognized by the World Economic Forum as a 2014 Technology Pioneer, the technology makes TruTag one the world’s most innovative companies.
