Abstract
The utility model relates to an IC card, in particular to a noncontact IC card specified passive expansion card. The width of the expansion card is less than or equal to 54mm, two interconnected closed electric conduction are arranged in the card. According to the noncontact IC passive expansion card, by using the principle of electromagnetic wave mutual inductance, an innovative design is provided, the signal receiving capability of the noncontact card is effectively increased, and the workshop of a card reader can be transferred, and the two-way adaptability of the card reader and the card is enhanced.
Description
Technical field
The utility model relates to IC-card, the special-purpose passive expansion card of particularly a kind of contactless IC card.
Background technology
Contactless IC card has another name called contactless card, and by the IC chip, induction antenna is formed, and is sealed in the standard polymer card no exposed parts fully.The read-write process of non-contact IC card is usually by accomplishing read-write operation through radiowave between non-contact type I C card and the read write line.
IC-card is from the magnetic card technique development, and apparent size is followed the standard of ISO/IEC7811 usually, that is: long is 86mm, and wide is 54mm, and thick is 0.76mm.It is the standard size of bank card.Along with the development of processing technology, the external form of noncontact I C card is varied, round, heart type and irregular type or the like are arranged, and size is varied especially, and thickness surpasses 1mm basically.
And a large amount of plug-in type contactless IC card read/write device on the market, because it to card external form strict restriction, causes a large amount of non-standard special-shaped cards to be difficult in this type of card reader, use (like call box etc.).
The utility model content
The purpose of the utility model is to provide a kind of contactless ic passive expansion card, and it can help special-shaped contactless ic to be stuck in the normal read-write in the standardized plug in type card read write line.
The purpose of the utility model realizes through following approach: the passive expansion card of a kind of contactless ic, and this expansion card is card-like, and the width of expansion card is less than or equal to 54mm, blocks built-in two interconnected closed conductive coils.
Further, the card of expansion card is provided with draw-in groove or the clip or the combination of the two of dress special-shaped card on one's body.
The passive expansion card of the utility model contactless ic utilizes electromagnetic wave mutual inductance principle; Propose innovative design, when effectively promoting non-contact card signal acceptance, also can the yard of card reader be shifted; Improved the two-way adaptation ability of card reader and card, it has following advantage:
1. the utility model is accomplished can adopt with the same production technology of existing card and is produced, and cost is very cheap.
2. utilize the utility model can expand the range of application of non-standard contactless smart card greatly, improve the service efficiency of smart card in user's hand.
3. utilize the utility model, can improve the utilization factor of card reader in the more existing read-write of accomplishing on such as the plug-in contactless card reader ultra thick, ultra wide IC-card.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further explain:
Fig. 1 is the utility model inner structure synoptic diagram;
Fig. 2 is the external structure synoptic diagram of the utility model embodiment one;
Fig. 3 is the side-looking structural representation of Fig. 2;
Fig. 4 is the side-looking structural representation of the utility model embodiment two;
Among the figure: expansion card 1, conductive coil 2, special-shaped card 3, clip 4, draw-in groove 5.
Embodiment
As shown in Figure 1, the passive expansion card of the utility model contactless ic, this expansion card is card-like; Adopt the generous of Standard Bank card; Its width is 54mm, and thickness is 0.76mm, and its length is that two standard cards are long; The closed conductive coil 2 that blocks built-in two interconnected formation mutual inductances, described conductive coil 2 coil winding numbers are four circles.This card adopts with the same production technology of contactless IC card and produces, and conductive coil 2 can adopt ultrasound wave coiling or etching antenna technology.Outside surface can adopt the PVC plastic package, is the card pattern.
Like Fig. 2, shown in Figure 3,, be provided with the clip 4 of plug-in mounting special-shaped card 3 on one's body at the card of expansion card 1 for fixing special-shaped card 3.
As shown in Figure 4, the card of expansion card 1 also can be provided with the draw-in groove 5 of putting special-shaped card 3 on one's body.
During use, special-shaped card 3 is inserted in clip 4 or the draw-in groove 5, expansion card 1 is inserted in the card reader, form mutual inductance through the conductive coil in the expansion card 12, card reader just can be read and write special-shaped card 3.
Claims (2)
1. passive expansion card of contactless ic, this expansion card is card-like, it is characterized in that: the width of expansion card (1) is less than or equal to 54mm, blocks built-in two interconnected closed conductive coils (2).
2. the passive expansion card of contactless ic as claimed in claim 1 is characterized in that: the card of expansion card (1) is provided with draw-in groove (5) or the clip (4) or the combination of the two of dress special-shaped card (3) on one's body.
