Sealys Security features

he increase in international travel, growing threats from terrorism, high levels of identity fraud as well as illegal immigration means that our travel documents, ID and healthcare documents must be highly secure.

At Gemalto we take these threats seriously by ensuring that the secure document selected can be trusted, by using technologies and materials that are difficult to copy, use and come by.

Security features can be overt and covert, visible and invisible.


Traditional high security features available for all Sealys documents include guilloches background printing, rainbow printing, invisible fluorescent printing or mixed into visible ink, micro-printing, OVIs and modified fonts just to name a few.

At Gemalto we recommend 100% polycarbonate datapages or cards, tamperproof solid card bodies that are impossible to delaminate and that enable the deployment of some very unique security features.

strong visible security feature is the Sealys Window - a transparent window created inside the card making it impossible to copy and enabling quick checking. Laser engraving and several optical elements can also be combined within the window. Any attempts by forgers to tamper with the document will be immediately visible.

The new family of Gemalto’s innovative Sealys Secure Surfac features enhances the security of polycarbonate identity documents by combining different effects: light reflection, movement and tactile effects.

Unique in the market, Sealys Edge Sealer is a laser engraving process applied during the personalization stage. Documents are laser-etched with markings along the edge of the document, thus adding an additional layer of security. The laser engravings ideally relate to the holder’s personal information, using their name, serial number, or other unique information.

Making forgery even more difficult, the Sealys Laser Sealer insures that criminals can’t change or add laser engraved information after personalization has taken place. The laser engraved image, signature or data is digitally manipulated to include slightly visible security marking. Post-lasering will be revealed by visible marks in the document.

Sealys secure documents have the highest electronic level of security with Sealys operating systems for electronic passports and other electronic identity documents, further enhancing the security of the document itself.

Sealys Color in Polycarbonate is the first laser printing solution to deliver an unalterable color image combined with the high security and exceptional durability of Polycarbonate at personalization stage.

As you will see on our web site, Gemalto has a wide variety of innovative security features that are available. These features are customizable according to your needs.
