Laminated Documents and Cards Including Embedded Security Features |
摘要 |
An anti-counterfeit feature for a multi-layer document or plastic laminated card is provided according to some embodiments. The laminated card can include an embedded layer including a radio frequency radiation absorbing or deflecting material. The card can be authenticated by detecting an absence or a modification of a radio frequency signal due to the card interfering with a radiation source. The laminated card can also include a pattern of perforations passing partially or fully through one or more layers of the card so as to produce an effect similar to a watermark in the assembled laminated card by giving the card a modified transparency in a pattern associated with the pattern of perforations. The card can be authenticated by observing a pattern of light through the perforations. |
