Problems solved by technology

Although this product has surpassed the technical scope of the traditional dual-interface smart card, from the perspective of product realization, there are also many defects, especially for the specific product realization and description of characteristics that deviate from existing standards. Apparently the inventor of this technology is not very proficient in the related technology of dual-interface smart card
Due to incomplete or insufficient technology disclosure and lack of necessary implementation data, professionals in the industry cannot realize products that meet practical value based on the disclosed technology

Abstract

The invention discloses a novel double-interface intelligent card. The card is formed by a card base (1), a double-interface intelligent card module (2) and a coupling amplification antenna (3). The card base is formed through laminating and pressing 2-6 layers of thin type insulating material. The coupling amplification antenna is a double-sided film circuit board and is formed by a group of radio frequency antennas and a group of plate condensers. The double-interface intelligent card module is formed by a carrier tape which is integrated with the radio frequency antennas and contacts, a double-interface intelligent card chip and a matching circuit. The coupling amplification antenna is arranged in an interlayer of an inner layer of the card base and simultaneously is laminated. The double-interface intelligent card module is arranged in a stepped groove of one side of the card base. The double-interface intelligent card of the invention simultaneously possesses a contact intelligent card function and a non-contact intelligent card function. Product performance can be increased and simultaneously most of production equipment and technology can be used so that production cost can be reduced and a production period can be shortened.

Description

technical field [0001] The invention relates to a smart card, in particular to a dual-interface smart card, a dual-interface smart card module and a radio frequency amplification antenna, which are suitable for application in the field of double-interface smart card packaging. Background technique [0002] In the field of smart card packaging, the application of smart cards is increasing, and more than 5 billion smart cards of various types are issued worldwide every year. At present, the smart card industry is developing towards technological innovation. New technologies are constantly emerging, new functions are increasing, and many old functions are constantly being improved and strengthened. In the future, new smart card service applications will continue to expand. In these developments At the same time, the improvement of the function and performance of the smart card is inevitable. [0003] At the stage when China is vigorously developing the secure transfer of finan...
