How does it work?
A hologram’s key feature is that it is interactive, allowing the user to see different images by changing the viewing angle. Covert features can be added to increase security, including microtext, nanotext, laser viewable images, and optical watermarks revealed by secure decoding keys. These features are authenticated only by those with the proper training and tools.
Typical Application/Use
Typical applications of 3M Holographic Authentication Products include securing electronics, pharmaceuticals, and government documents. They are available as opaque metalized or transparent materials. Typical formats include hot stamping foil, pressure sensitive labels, overlaminants, or security strips on various label stocks.
How do you verify?
Covert images are visible through an inexpensive verifier key. Overt holography is verified visually, using no tools. Additional covert features may be verified using magnification or lasers.
