Abstract

The utility model relates to a non-contact type IC card. In the utility model, the purpose of the reduction of the volume can be reached by the change of the size of a linear diameter and the quantity of coils. The IC card of the utility model has the advantages of no easy damage and portability. The utility model is an IC card suitable for schools.

Description

Non-contact IC card

The utility model relates to a kind of non-contact IC card.

Use the drawback of Dining Ticket along with microelectric technique, development of internet technology and universities and secondary specialized schools, begin in the early 1990s, each school begins to use the microcomputer charging administration system in toll site such as dining rooms, the situation that the consumption card that the student held also coexists from early stage punching photoelectric card, magnetic card, hidden photoelectric card up till now, IC-card, non-contact IC card, wherein contactless IC card system progressively obtains affirming of user with advance, reliability of operation, the convenience of its technology, and will become the development trend in this field.

But it is good that non-contact IC is stuck in the institutional settings operating position, and reflect that the part student of school consumption card easily loses and bad card phenomenon is arranged, because the cost higher (about 20 yuan) of non-contact IC card, the student loses relatively large.Cause the main cause of losing and going bad card to be:

1. be that middle school student much do not have wallet in addition owing to student spy, and the best place of non-contact IC card is to be placed in the wallet.Non-contact IC card inside have chip and around inductive coil, the wire rope handling that therefore can not punch on the card, card can only be placed in the pocket at any time.So card is lost than being easier to.

2. because student's youth is active, is placed on pocket and easily bends, thereby cause the damage of card.At the bad card of student and the problems referred to above of be inconvenient to carry, we are when developing non-contact IC card microcomputer charging administration system, for the damage that prevents non-contact IC card with lose.

The non-contact IC card that the purpose of this utility model is to provide a kind of and is easy to carry, should not damages.

The purpose of this utility model is achieved through the following channels: non-contact IC card, this contactless standardization IC-card is made up of card base, coil and chip three parts, its winding wire directly is that 0.1 millimeter, coil number are 5 circles, the coil of the contactless standardization IC-card after the improvement is that line directly is 0.12 millimeter a insulated copper wire, and its coil number is 6.5 circles.Transparent plastic shell has been sealed up in card outside after the improvement.

The utility model is not fragile, is easy to carry, and is a kind of desirable non-contact IC card of using in school of being suitable for.

Below in conjunction with accompanying drawing the utility model is described in further detail:

Fig. 1 is the structural representation of the utility model non-contact IC card;

Fig. 2 is that the A-A of Fig. 1 is to cut-open view;

Fig. 3 is the structural representation of existing non-contact IC card;

Fig. 4 is that the B-B of Fig. 1 is to cut-open view;

Fig. 5 is the structural representation of sealing up the non-contact IC card behind the transparent plastic shell;

Fig. 6 is that the C-C of Fig. 1 is to cut-open view.

For the damage that prevents non-contact IC card with lose, the utility model has been done following improvement:

At first, dwindled the size of card.Because non-contact IC card is that the variation by coil internal magnetic field, magnetic flux produces induced voltage, electric current comes recorded information.Therefore dwindle coil and can not change voltage, electric current in the coil, like this, just can only increase line footpath and increase coil number keeps the voltage, the electric current that produce the same with voltage, the electric current of former line and primary winding generation, only in this way, could keep nonstandard card and standard card that identical technical indicator is arranged.As Fig. 1, figure, Fig. 3, shown in Figure 4, the coil 2 of contactless standardization IC-card is that line directly is that 0.1 millimeter insulated copper wire, coil number is 5 circles, and the coil 2 of the card after the improvement is that line directly is that 0.12 millimeter insulated copper wire, coil number is 6.5 circles.

Secondly, the card after the improvement is sealed up transparent plastic shell 4 and is become one, promptly nonstandard non-contact IC card, its structure such as Fig. 5, shown in Figure 6.Like this, just can make card be difficult for being bent and producing bad the card.Simultaneously, card is again a fancy goods, and more convenient student carries and uses.Because nonstandard ten is not fragile, being difficult for can the husband, so just avoided the student since bad ten with lose card with not loss.

Claims

1. non-contact IC card, this contactless standardization IC-card is made up of card base [3], coil [2] and chip [1] three part, its winding wire directly is that 0.1 millimeter, coil number are 5 circles, the coil of the contactless standardization IC-card after it is characterized in that improving is that line directly is 0.12 millimeter a insulated copper wire, and its coil number is 6.5 circles.

2. as right 1 described non-contact IC card, transparent plastic shell [4] has been sealed up in the card outside after it is characterized in that improving.
