With Thales Gemalto Window Lock security feature, Thales presents a new security concept for the protection of the holder portrait against any subsequent change by means of additional laser engraving.
The technology for polycarbonate 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.
A friendly ghost to prevent tampering
Window Lock implements a "negative" personalization process where the light-coloured image is personalized by metal ablation. Hence, fraudulent manipulation of the cardholder portrait could easily be detected.
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.
