What it is?
Security threads are thin ribbons which are directly embedded or threaded through the substrate to protect, such as banknote paper.
How do you detect it?
Authentication of a substrate with a security thread is usually done through visual inspection under the help of specific light sources.
How does it work?
Security threads are embedded during the production of the substrates, for instance paper.
What do we think about this technology?
This technology is one of the most useful overt solutions for authenticating banknotes by consumers. However, it is rarely used in the field of brand protection. Indeed, it requires the substrate to have characteristics that accommodate the integration of the thread which is usually not the case for folding boxes; it also adds significant cost and still remains easy to counterfeit.
In practice, it is better to use Cryptoglyph® technology since it is more secure, easier to deploy and enables monitoring of detections (particularly useful for excise stamps).
Field of application
Banknotes and passports.
