Trüb has launched a new personalization security feature for laser-engraved polycarbonate travel and identity documents. The tru/window Lock security feature offers a better protection of the card holder portrait against manipulation after issuance.

Trüb’s new security feature tru/window Lock is designed for laser-engraved polycarbonate documents such as national identity cards and passport data pages. 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. Hence, a fraudulent manipulation of the card holder portrait could easily be detected. With tru/window Lock, Trüb presents a security concept which is easy to understand and to verify, resulting in further increased security level of travel and identity documents.

The tru/window Lock security feature has been presented for the first time at ‘Cartes & Identification’ exhibition held in Paris in November 2011. [www.trueb.ch]
