| 摘要 |
<p>The invention relates to an insert (1) for a multilayer chip card (15), including an intermediate sheet (7) and, on either side of the intermediate sheet (7), at least one outer sheet (11, 13) having a face in close contact with the corresponding face of the intermediate sheet (7), said intermediate sheet including at least one recess (9) prior to the lamination of the insert. The insert is characterised in that at least one of the outer sheets (11, 13) is made from a fluent material, such that, when the intermediate sheet (7) is being laminated with the outer sheets (11, 13), part of the material of the outer sheets (11, 13) moves into the recess (9) in the intermediate sheet, thereby forming a visual and/or tactile defect on the surface of the insert (1), indicating whether of not the insert and/or the chip card is authentic.</p> |
