SECURITY AND/OR VALUE DOCUMENT |
摘要 |
The security method is adopted valuable documents that criminals may wish to forge, e.g. banknotes. The method of preventing forgery is to produce a banknote with a verification element (2). When the banknote is folded, the security element produces a specific visual effect when aligned with a security marking (3). The verification element is in the form of a transparent window that has a lens raster pattern and this interacts with the security marking. |
