    摘要: An optically variable security element for securing valuable articles that viewing-angle-dependently displays a motif having at least one curve depiction that, from a first viewing direction, is visible as an initial curve having two or more connected, non-collinear segments and that, when the security element is tilted about a predetermined axis, splits into the individual segments in that the segments of the initial curve move alternatingly in different directions away from the initial curve. Each of the segments has associated with it one movement segment in the form of a sub-region of an areal motif region, such that, from the first viewing direction, the segments display the initial curve having the connected segments and that, from viewing directions tilted about the predetermined axis, they display curve depictions in which, with increasing tilt angle, the segments lie alternatingly in different directions increasingly further away from the initial curve.

    摘要: A manufacturing method of a smart card. The manufacturing method comprises: respectively hollowing out a plurality of substrates to obtain a plurality of hollowed-out substrates (101); synthesizing the plurality of hollowed-out substrates to obtain a multilayer synthesized hollowed-out substrate (102); filling the synthesized hollowed-out substrate with an internal insert (103); and coating the synthesized hollowed-out substrate with adhesive to obtain the smart card (104). By adopting the technical solution that a multilayer synthesized hollowed-out substrate is obtained by synthesizing a plurality of hollowed-out substrates, and the synthesized hollowed-out substrate is filled with an internal insert, the production difficulty of the smart card with a function of human-computer interaction is reduced, and the production efficiency is increased.
