| 摘要 |
<p>The invention relates to an identification card (or chip card) (A) comprising a substrate (S) that consists, for example of paper, on the front face (V) of which text or similar is printed. A conductive pattern, which contains a single coil winding (10) of an antenna of the transponder, in addition to two first layers (6, 8) of two capacitors (C1, C2), is printed on the rear face (R). The counter-electrode, i.e. the other layer in relation to the two first layers of the capacitors, is formed by a conductive strip (2) that is located on the front face (V) and forms a security characteristic of the identification card (A). A transponder chip (4) makes mechanical and electrical contact with the conductive pattern.</p> |
