Abstract

The invention relates to the field of smart cards, in particular to a double-interface card. The double-interface card comprises a chip and an induction coil, wherein the induction coil comprises a first end and a second end, the first end of the induction coil is welded to a first copper sheet, and the second end of the induction coil is welded to a second copper sheet. A positive wire of the chip is welded to the first copper sheet, a negative wire of the chip is welded to the second copper sheet, and the two ends of the induction coil are electrically connected with the positive electrode and the negative electrode of the chip respectively. The double-interface card effectively improves the making efficiency of the double-interface card and lowers the making cost of the double-interface card.

Description

technical field [0001] The invention relates to the field of smart cards, in particular to a dual-interface card. Background technique [0002] The dual-interface card is a smart card based on a single chip that integrates a contact interface and a contactless interface. These two interfaces share the same microprocessor, operating system and memory. The dual-interface card includes a microprocessor chip and an induction coil connected to the microprocessor. The electromagnetic field generated by the reader provides energy, and realizes energy supply and data transmission through radio frequency. Since one card provides contact interface and non-contact interface at the same time, the dual-interface card combines the advantages of contact and dual-interface cards, and has wide applicability. Use in all occasions. [0003] The production efficiency of the existing dual-interface card is low, and the reject rate is high during the production process, so that the existing dua...
