With Sealys Window Lock
, Gemalto presents a new security concept for the protection of the holder portrait against any subsequent change by means of additional laser engraving.
Developed in Switzerland by Trüb, now part of Gemalto, the technology is based on a sophisticated laser ablation personalization process on a metallic foil which is integrated into a transparent window. A ghost image is laser personalized into the metal foil so that a simultaneous manipulation of the card hold portrait and ghost image after issuance of the document will leave visible traces.
Sealys Window Lock implements a "negative" personalization process where the light-colored image is personalized by metal ablation. Hence, a fraudulent manipulation of the card holder portrait could easily be detected.
Sealys Window Lock presents a highly innovative security concept which is easy to understand and to verify, resulting in further increased security level of travel and identity documents.
