Dual-chip transaction card and multi-chip transaction card

Abstract

The invention relates to a dual-chip transaction card and a multi-chip transaction card, which can be used in the financial field or other fields. The dual-chip transaction card comprises a card main body which comprises a first surface and a second surface which are opposite to each other; the first chip, the first non-wiring coil and the first insulating part are arranged on the first surface, and the first non-wiring coil is connected with the first chip and is disconnected by the first insulating part; when the first insulating part is in contact with the human tissue, the first non-wiring coil is conducted; the second chip, the second non-wiring coil and the second insulating part are arranged on the second surface, and the second non-wiring coil is connected with the second chip and is disconnected by the second insulating part; and the second non-wiring coil is conducted when the second insulating part is in contact with the human tissue. According to the double-chip transaction card, the damage rate of the transaction card is reduced, the possibility that lawbreakers read the card information or swipe the card by unconnected card reading equipment is avoided, the convenience of chip switching is improved, and the exclusiveness of chip operation is ensured.

Description

technical field [0001] The invention relates to the financial field, in particular to a double-chip transaction card and a multi-chip transaction card. Background technique [0002] Now banks issue single-chip cards, and one card can only provide the business functions of one account. When the card has insufficient balance or is declined for other reasons, the customer can no longer use the card for transactions. Therefore, if customers need to use bank cards when traveling, they generally carry two or more cards. [0003] In order to improve the convenience for customers to use bank cards, and also to reduce the cost of preparing bank cards for banks, dual-chip cards or even multi-chip cards will inevitably appear. For non-contact transactions of dual-chip cards or multi-chip cards, the reading and writing of the chip depends on the induction of the coil. If the contactless induction coils of the two chips are powered on at the same time, it will greatly affect the induct...

Problems solved by technology

[0004] Based on this, it is necessary to provide a dual-chip transaction card and a multi-chip transaction card for the problem that multi-chip cards are difficult to accurately identify target chips during non-contact transactions, aiming at improving the performance of dual-chip cards and multi-chip cards during non-contact transactions. Chip exclusivity and convenience of chip switching
