DIOVIS brand protection technology utilizes specific optical properties to enable accurate and easy visual verification by non-experts. In addition to the first-line check provided by the diffractive images,
DIOVIS has three other ways to verify authenticity:
(1) Color-shift verification, (2) Handy Viewer verification, (3) Machine verification through specialized sensor.

New legislation* covering all technologies and products used for counterfeit detection has been established by China. Under this legislation, all anti-counterfeit products to be used in China must be registered with the Chinese government in advance. If any anti-counterfeit products are used prior to the registration, the user shall be ordered to take corrective measures and may be subjected to administrative sanctions such as fines.
NHK Spring’s DIOVIS has been duly registered and can thus be legally used in China.
(Anti-Counterfeit Product Registration Number: ZC110002)

Partially-transparent-type DIOVIS
This new product has increased the counterfeit detection capability over the existing model (TG-80).
1. Color shift effect, whereby the colors of the special material shift according to the viewing angle.
2. Handy Viewer verification
Anyone can easily verify authenticity through viewing with the Handy Viewer.
Right side window ( ○ )  Hologram pattern can be seen.
Left side window ( ● ) Hologram pattern cannot be seen.
DIOVIS is the only product that has this unique characteristic.
3. Machine verification through specialized sensor
Using a specialized sensor, it is possible to perform verification of a large number of DIOVIS automatically, accurately, and quickly.
4. Peeling fracture type sticker makes reuse difficult
DIOVIS features peeling fracture characteristics through the use of an easily breakable material, a strong adhesive, and a large number of incisions, making it extremely difficult to reuse stickers.
5. Optional laser marking available
Laser marking of serial numbers, etc., is possible, allowing the introduction of authentication systems with superior traceability. |

Transparent-type DIOVIS
As is the case with DIOVIS Standard Grade, Transparent-type DIOVIS also allows Handy Viewer verification.
In light of its transparent property, TG-80N can be applied to the surface in cases where design restrictions apply to the preferred point of application. For example, TG-80N can be applied on corporate logos, bar codes and photographs for passports or employee identification, etc. |

Transfer-type DIOVIS
DIOVIS foil can be stamped to labels made from various kinds of materials. Since DIOVIS foil is stamped to a part of the label, TG-80F has broad choice of design, and can be combined with other security devices. |

The following versions exceeding the DIOVIS Standard Grade are also available.
Check and verification can be completed using the same Handy Viewer
TG-120 High-function grade I
TG-140 High-function grade II
