Taggents means tiny tracers in the inks or base materials that can be traced and used to authenticate the document with a reader.
This Taggents feature is effective primarily in documentpresent situations where the original document can be examined by a trained professional or scanned with a specialized 3-illumination ID scanner and analyzed with adequate forgery detection technology.
Usability in online and mobile onboarding situations is challenging as the examination is made not on the physical document but on a photograph or scanned image of it.
