Covert Black Technology

Secure electronics, pharmaceuticals and other high value products via holography and patented, proprietary retroreflective technology. Combine easily authenticated overt and covert security features for an attractive solution to brand protection.

How does it work?

The overt security is a unique, black hologram, which allows the user to see variable images at different viewing angles. The covert security utilizes retroflective technology to reflect a secure covert image when illuminated with a focused light source. The covert features are authenticated only by those with the proper training and tools.

Typical Application/Use

Typical applications of 3M Retroreflective Authentication Products include securing electronics, pharmaceuticals, and other high value products. Typical formats include pressure sensitive labels or security strips on various label stocks.

How do you verify?

Overt holography is verified visually, using no tools. Covert images are visible under a focused light source such as a 3M™ Handheld Retroreflective Verifier.

Technology provides two levels of verification:

Attractive, overt holographic images move when viewing angle is changed, encouraging user interaction.
Strong retroreflective covert security features visible under a focused light source such as a 3M™ Handheld Retroreflective Verifier.

Covert images can be customized and are available in a variety of colors.
High resolution security holography on black background increases barrier to simulation or counterfeiting.
Overt holographic images can be a custom designed or a secure standard design.
Optional features can increase security:
