What it is?
Track and trace is used in logistics to follow products throughout the supply chain. A track and trace system keeps track of past and current locations of products, through the use of unique product identifiers (UIDs).
What do we think about this technology?
In theory, track and trace does not, by itself, bring any level of protection against counterfeiting since it can be easily duplicated. To effectively use track and trace systems they should be used in an environment where many code reads are performed, and the readings are geo localized. Without this, it is difficult to distinguish reads of duplicated codes/codes from reading the same code on a product multiple times. A different approach is to combine it with the scratch-off approach, but that is itself unreliable by nature as mentioned above.
If only authentication is the objective, then it is simpler and more cost effective to use a dedicated anti-counterfeit technology, like Cryptoglyph® or AlpVision Fingerprint®. If both serialization and authentication are required, then AlpVision software applications can seamlessly integrate with any track and trace technology.
