It should be noted that the double-chip transaction card and the multi-chip transaction card disclosed in the present application can be used in the financial field, and can also be used in any fields other than the financial field.
As shown in fig. 1, one embodiment of the present application discloses a dual-chip transaction card, comprising: a card body 10, the card body 10 having opposing first and second surfaces; a first chip 11, a first non-wiring ring 12 and a first insulating member 13 disposed on the first surface, wherein the first non-wiring ring 12 is connected to the first chip 11 and is disconnected by the first insulating member 13; the first insulation part 13 conducts the first non-wiring coil 12 when contacting with the human tissue; a second chip 14, a second non-wiring coil 15 and a second insulating member 16 provided on the second surface, wherein the second non-wiring coil 15 is connected to the second chip 14 and is disconnected by the second insulating member 16; the second insulating member 16 conducts the second non-wiring coil 15 when it is in contact with the human tissue.
For example, the card body 10 may be PVC plastic base (Polyvinyl chloride). The transaction card may be a bank card or other card with transaction functions. The human tissue may be a finger or other body part. The switching and selecting of the chips can be realized by contacting human tissues with the first insulating part 13 or the second insulating part 16, so that the chip switching and selecting are convenient and quick. The principle behind this is to use the electrical conductivity of human tissue. Human tissue is electrically conductive because human body contains a large amount of water, and electrolytes are dissolved in human body fluid to form charged ions, which are directionally moved in the body under the action of an external electric field to form electric current.
In fig. 1, the first chip 11, the first non-wire coil 12, and the first insulating member 13 are shown by solid lines to indicate that they are located on the first surface; the second chip 14, the second non-wiring coil 15 and the second insulating member 16 are shown by broken lines to indicate that they are located on a second surface opposite to the first surface. Wherein the first non-wiring ring 12 is connected to the first chip 11 and is disconnected by the first insulating member 13, as shown in fig. 1, and the first non-wiring ring 12 is connected to both ends of the first insulating member 13. As shown by the broken line in fig. 1, the second non-wiring coil 15 is connected to the second chip 14 and is disconnected by the second insulating member 16, and the second non-wiring coil 15 is connected to both ends of the second insulating member 16.
Illustratively, when a user needs to perform a contactless transaction with a bank card, the user may contact the first insulating member 13 on the first surface with a finger to conduct the first non-wiring ring 12, and then approach the transaction card to a non-connected card reader, which may read data stored in the first chip 11 through the first non-wiring ring 12. At this time, the second chip 14 on the second surface is in an inactive state, and since the second non-wiring coil 15 is disconnected by the second insulating member 16, it is in an open circuit state, and even if the non-connected card reader is approached, the non-connected card reader cannot read data in the second chip 14. When a transaction needs to be conducted by using the second chip 14, the finger is moved away from the first insulating part 13, the connection of the first non-wiring coil 12 is disconnected, and the second insulating part 16 is contacted to realize the connection of the second non-wiring coil 15, at this time, the information read by the non-wiring card reader is the data in the second chip 14, and the data in the first chip 11 can not be obtained any more.
Above-mentioned double-chip transaction card utilizes human tissue's electric conductivity, realizes switching on to different non-wiring circuit through the method of human tissue contact insulating part, realizes selecting and switching different chips high-efficiently, in addition, owing to need not to use physical switch, does not have mechanical loss, has consequently reduced the harm rate of transaction card, has solved double-chip transaction card and has switched over the loaded down with trivial details of chip, the fragile problem of card.
And when the transaction card is not used, because no human body tissue is in contact with the insulating part, the non-wiring ring of the transaction card is in an open circuit state, and the non-contact physical function is in a closed state, so that the possibility that lawless persons read card information or steal the card through non-contact card reading equipment is avoided, and the confidentiality of the card is ensured.
In one embodiment, as shown in fig. 2 and 3, the first non-wire loop 12 is circumferentially disposed on the edge of the first surface, and the second non-wire loop 15 is circumferentially disposed on the edge of the second surface.
Through encircle to set up in the card edge with non-wiring circle, can improve non-wiring circle's sensing ability with the length and the area coverage maximize, promote the sensitivity that card information read. Illustratively, the first and second non-wire coils 12 and 15 may be copper coils or other metal coils.
In one embodiment, as shown in fig. 2 and 3, the first chip 11 and the first insulating part 13 are both disposed on a center line of the first surface and are disposed at two opposite ends of the card body 10, respectively; the second chip 14 and the second insulating member 16 are both disposed on the center line of the second surface and are disposed at two opposite ends of the card body 10, respectively; wherein the first insulating member 13 and the second insulating member 16 are disposed in a staggered manner.
Through misplacing the first insulating part 13 and the second insulating part 16, a finger can be prevented from contacting the second insulating part 16 while contacting the first insulating part 13, two non-wiring rings are prevented from being simultaneously electrified and conducted to generate interference, and the induction effect of the non-wiring card reader is ensured.
In one embodiment, the first insulating member 13 includes: a first insulator module, a first contact pad and a second contact pad; the first contact piece and the second contact piece are positioned on two sides of the first insulator module and are respectively connected with the first non-wiring ring 12; the distance between the first contact piece and the second contact piece is smaller than the width of human tissues; the second insulating member 16 includes: a second insulator module, a third contact pad, and a fourth contact pad; the third contact piece and the fourth contact piece are positioned on two sides of the second insulator module and are respectively connected with the second non-wiring ring 15; the distance between the third contact piece and the fourth contact piece is smaller than the width of human tissues.
For example, fig. 4 shows a schematic structural view of the first insulating member 13, wherein a first contact piece 132 and a second contact piece 133 are located on both sides of the first insulator module 131 and are respectively connected to the first non-wire coil 12. Alternatively, the first contact pad 132 and the second contact pad 133 may be copper pads, iron pads, silver pads, or other conductive metal pads. In order to ensure that the first non-connecting coil 12 can be conducted after the human tissue contacts the first insulating member 13, the distance between the first contact piece 132 and the second contact piece 133 needs to be smaller than the width of the human tissue. For example, if the human tissue is a finger, the distance between the first contact piece 132 and the second contact piece 133 needs to be smaller than the width of the finger. Further, in order to ensure that each finger can conduct the first non-wire coil 12, the interval between the first contact piece 132 and the second contact piece 133 may be set smaller than the width of the thumb of an adult.
Illustratively, the structure of the second insulating member 16 is the same as that of the first insulating member 13.
By arranging the non-wiring ring contact pieces on two sides of the insulator module and enabling the distance between the non-wiring ring contact pieces to be smaller than the width of human tissues, the non-wiring ring can be disconnected by the insulating part when no human tissues contact; and human tissues can be ensured to simultaneously contact the non-wiring coil contact pieces on two sides of the insulator module after contacting the insulating part, so that the non-wiring coil is conducted.
In one embodiment, the first chip 11 has stored therein personalization information related to the first card number; the second chip 14 stores personalized information related to the second card number; the first card number and the second card number belong to the same customer; wherein the personalization information comprises: and writing the information for transaction of the chip during card manufacturing.
The personalized information is information written into the chip for card transaction when the card issuing mechanism produces the card for the customer. The personalized information is set by the client, can comprise a password, a mailbox, an address and the like, and can be used for performing security verification during card transaction, so that the security of the transaction is improved. For example, a user has a first card number and a second card number, and in order to improve the convenience of card transaction, the first chip 11 may store personalization information related to the first card number, and the second chip 14 may store personalization information related to the second card number. Thus, one card can provide the service functions of two accounts. When one account can not transact because of insufficient balance or other reasons, the other account can be conveniently switched to continue to complete the transaction.
The double-chip transaction card can reduce the cost for preparing the transaction card and improve the convenience for a user to use the transaction card.
In one embodiment, as shown in fig. 5 and 6, the dual chip transaction card further comprises: a first cover molding 17 covering the first surface; the first cover molding 17 includes a first non-contact sheet window 171 for exposing the first insulating member 13; a second cover molding 18 covering the second surface; the second cover molding 18 includes a second non-contact sheet window 181 for exposing the second insulating member 16.
