AI Technical Summary
Technical Problem
Existing data carriers for secure articles, such as passports, are susceptible to forgery due to security elements like lenticular lens arrays and transparent windows that can be easily separated or reused, leading to counterfeiting risks and inefficient use of space.
Method used
A data carrier design that integrates a lens array above a security element with a laser marking extending through the carrier body, linking the two and making separation more difficult, featuring a tactile marking that can be felt and remains visible under different angles.
Benefits of technology
Enhances security by preventing the separation and reuse of lens arrays, providing a tactile and visible laser marking that deters tampering and maintains the integrity of the security element.

Abstract
A data carrier (1) for a secure article (1000) extends along an extension direction (E) and comprises a carrier body (2), at least one lens array (3), and at least one security element (4). The lens array (3) is arranged above the security element (4) with respect to the extension direction (E) and the security element (4) is arranged within the carrier body (2). The lens array (3) and the security element (4) are configured such, that an appearance of the security element (4) changes depending on a viewing angle (α1; α2) under which the data carrier (1) is viewed. The data carrier (1) comprises at least one laser marking (5), and wherein, when seen along the extension direction (E), the laser marking (5) extends from the lens array (3) at least partially through the carrier body (2) towards the security element (4).
