Abstract: The present invention relates to a data carrier, especially a security document, such as an identification card, e.g. a passport or a driving license, a credit card and a bank card, the data carrier comprising authentication data comprising personalized data, and as a security feature, an array of lenticular elements being arranged to provide only from predetermined angles of view an image of at least a piece of authentication data of said authentication data. In or to make the data carrier impossible or at least very difficult to copy and forge, the array of lenticular elements is provided with a complex structure providing a further security feature.

Abstract: The present invention relates generally to a data carrier comprising an opaque layer and a method for making the data carrier. During personalization phase, the ablation of the opaque layer by laser through the data carrier allows to define a see-through portion of the data carrier carrying opaque security, said see-through portion having an improved security corresponding to opaque embossing pattern overlapping at least partially the opaque security partially destroyed. Said defined see-through portion carrying opaque security partially destroyed with opaque embossing pattern on its surface is even more difficult to reproduce by forger, even more difficult to remove, replace or exchange and easy to check.
