How the Varcode Smart Tag™ Works


The Varcode Smart Data Solution is a next-gen solution for monitoring the temperature of products throughout the supply chain. At the system’s core is Varcode’s Smart Tag, which enables low-cost, multipoint track & trace from product origination to its final destination.

The Smart Tag™ is a dynamic barcode, where the black and white lines change based on temperature and time. Our custom-tuned mixture reacts to temperature change over time and expands across the barcode.

With just a scan, our Smart Tag™ eliminates interpretation errors and digitizes data.
