Double-interface metal intelligent chip card and manufacture method

Abstract

The invention discloses a double-interface metal intelligent chip card and a manufacture method. The double-interface metal intelligent chip card comprises a metal card body. The metal card body is provided with an interlayer, a printing sheet layer and a transparent protection layer which are positioned on the metal card body. The metal card body, the interlayer, the printing sheet layer and the transparent protective layer constitute a card base for the intelligent chip card. The base card is provided with a concave cavity for containing an IC module; the metal card body is a wave-absorption material metal card body; the interlayer is provided with an induction antenna; the IC module comprises a chip and a coupling micro antenna which is electrically connected to the chip; and the IC module can perform the information exchange between the chip and a reader through electromagnetic coupling between the coupling micro antenna and the induction antenna and the electromagnetic coupling between the induction antenna and the induction coil of the reader. The invention solves the technical problem that the metal card hardly realizes double-interface chip clamping contact type function and a non-contact type communication function at the same time, and provides a new double-interface IC metal card which is good in touching, has metal texture and can realize a double-interface transaction function.

Description

technical field [0001] The invention belongs to the technical field of smart IC cards, and more specifically relates to a smart chip card capable of adopting contact and non-contact communication methods and a manufacturing method thereof. Background technique [0002] With the continuous development of smart card technology in recent years, all kinds of magnetic stripe cards and IC cards have been widely used in finance, medical care, public transportation, security systems, telephone communications, social security and other fields. In order to attract more customers to use their The issued cards have launched cards with different structures and styles. Distinguished by the communication method between the card and the card reader, the existing IC cards are mainly divided into two categories: contact IC cards that can write and read information by contacting special equipment, and those that can only be written by approaching special equipment And a non-contact IC card th...

Problems solved by technology

However, batch processing of this kind of metal card is difficult and costly, and the most important thing is that the dual-interface transaction function cannot be realized

[0006] The above two cards are made of metal on one side, the edge of the body or the body itself. The IC card is made of metal film or metal sheet, which further improves the overall appearance of the card, making it more high-end and atmospheric, providing More card styles improve the durability and tactile experience of the card, but because the card has a metal layer, the metal layer has a shielding effect on the electromagnetic wave signal sent and received by the antenna, so the card can only be a single contact Cards, the sensing distance of non-contact cards is reduced by the shielding effect of the metal layer, which cannot meet the needs of users
