Embodiment Construction
[0014] see figure 1 , 2 , the present invention includes the front adhesive film 3, the front printing layer 4, the front substrate layer 5, the antenna layer 6, the reverse substrate layer 8, the reverse printing layer 9, the reverse adhesive film 10 attached in sequence, and the front adhesive film 3 The outer surface is equipped with a double-interface chip 1 through a hot-melt adhesive tape 2, especially: the front substrate layer 5 and the back substrate layer 8 all adopt a holographic mirror substrate, and the antenna layer 6 and the back holographic mirror substrate An intermediate diaphragm layer 7 is added between the layers; the antenna length×width×spacing×number of turns in the antenna layer 6=81mm×49mm×0.2mm×4 turns.
[0015] In this embodiment, the front adhesive film 3 and the reverse adhesive film 10 are both US KP PVC adhesive film FL2 with a thickness of 0.051 mm.
[0016] The thickness of the holographic mirror substrate described in this embodiment is 0.1...

Abstract
The invention relates to the technical field of electronic information, in particular to a holographic mirror surface high-grade double-interface wire-winding welding IC card. The IC card comprises a front-face glue film, a front-face printing layer, a front-face substrate layer, an antenna layer, a middle separation film layer, a back-face substrate layer, a back-face printing layer and a back-face glue film, the front-face glue film, the front-face printing layer, the front-face substrate layer, the antenna layer, the middle separation film layer, the back-face substrate layer, the back-face printing layer and the back-face glue film are attached in sequence, and a double-interface chip is patched on the outer surface of the front-face glue film through hot-melting adhesive tape. The IC card is characterized in that holographic mirror surface substrates are adopted in the front-face substrate layer and the back-face substrate layer, and the middle separation film layer is additionally arranged between the antenna layer and the back-face holographic mirror surface layer; length *width*distance*the number of turns of an antenna in the antenna layer is 81 mm*49 mm*0.2 mm*four turns. The appearance of the IC card has the metal color effect, the attractive effect and grade of the card are greatly improved, individuality is highlighted, the needs of high-end people can be met, and the card is mainly applied to the fields of finance, traffic, identity authentication, electronic payment and the like.
Description
technical field [0001] The invention relates to the technical field of electronic information, in particular to a high-grade dual-interface wire-wound welding IC card with a holographic mirror surface. Background technique [0002] At present, the dual-interface (IC) card technology at home and abroad is relatively mature. The principles of the wire-wound antenna dual-interface (IC) card and the silk-screen antenna dual-interface (IC) card are the same, but the antenna technology and antenna materials are different. These two dual-interface cards have both contact and non-contact functions. The contact function is performed through peripheral equipment and contact points. The non-contact function is that the card reader sends a set of electromagnetic waves with a fixed frequency to the IC chip. There is an IC in the card. The frequency of the series resonant circuit is the same as that of the card reader, so that electromagnetic resonance can be generated, so that there is c...
