Embodiment
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is IC-card bearer plane form constitutional diagram of the present invention.IC-card 101 is combined with plane form by carrier 102 and carrier 103,106 is Separable combination band, and in carrier 102, comprising IC chip 1 104,108 is the signal antenna of IC chip 104, in carrier 103, comprising IC chip 2 105,107 is the signal antenna of IC chip 105.By Separable combination band 106, carrier 102 and 103 can be combined as to an effective IC-card with plane form, at ordinary times by carrier 102 and within 103 minutes, open keeping, avoid losing simultaneously.
IC chip carrier of the present invention is not limited to traditional IC-card sheet, can be other any form, as key ring formula, hanging type.
Fig. 2 is IC-card carrier lamination form constitutional diagram of the present invention.201 is Separable combination band, by 201, the carrier of the carrier of IC chip 1 and IC chip 2 is combined as to an effective IC-card with lamination form.
IC chip carrier of the present invention is not limited to traditional IC-card sheet, it can be other any form, as student wears chest card (IC1) and mess card (IC2) builds up combination, cell-phone cover (IC1) and conventional P VC card (IC2) build up combination, and the additional IC1 of SIM cards of mobile phones and conventional P VC card (IC2) build up combination.
Fig. 3 is IC-card Card Reader process flow diagram of the present invention.IC-card during near card reader, first reads the identifying code of IC1, by judgement, if failure finishes authentication, if the identifying code of IC2 is read in success, by judgement, if failure finishes authentication, if read-write operation is carried out in success, completes authentication and operation.
Fig. 4 is that IC-card radio frequency powered of the present invention regulates the schematic diagram of start-up time by RC constant.Because a card reader reads IC1 and IC2 can produce conflict simultaneously, IC1 is that IC chip 1, IC2 are IC chip 2, so control the power-on time of IC chip by RC circuit, thereby control the work start-up time of IC chip, reach the object of the sequence starting of two or several IC chips.In Fig. 4, coil L and capacitor C 1 form LC resonant circuit, it is radio frequency powered lc unit, be used for receiving the electromagenetic wave radiation of card reader, rectification by diode D is converted into direct current by LC resonance current, by serial connection current-limiting resistance R1 or R2, to capacitor C 2 chargings, R1 or R2 and C2 form charhing unit, and C2 is full of after electricity for IC chip provides working power.This shows that R1 and C2 or R2 and C2 form RC circuit, the time constant of RC circuit can change by resistance in the situation that capacitance values is identical, in Fig. 4 of the present invention, the resistance of current-limiting resistance R1 and R2 is different, to obtain different charging rate RC values, thereby make IC1 and IC2 obtain the asynchronism(-nization) of normal power voltage, like this start-up time of IC1 and IC2 also different, thereby avoided car reading conflict.
Fig. 5 is that to adopt key chain be the embodiment of IC1 carrier in the present invention.In figure, carrier 102 and carrier 103 are separable, have an aperture 501 on carrier 102, by aperture 501, can be worn and be hung on key chain or on any lanyard, like this can printed patterns on carrier 103, and carrier 102 can safekeeping.
Fig. 6 is that the carrier of IC chip 1 of the present invention is the embodiment of SIM cards of mobile phones.In Fig. 6, carrier 102 is SIM cards of mobile phones, 601 chips that are SIM cards of mobile phones.Another carrier combining that matches with carrier 102 is PVC card.
Fig. 7 is that IC chip carrier of the present invention is the embodiment of two independent PVC cards.In Fig. 7, carrier 102 and carrier 103 are independent PVC cards, and PVC card can be onesize, also can small one and large one, and ticket-holder is put in large being convenient to, and little being convenient to taken care of.
Further, little PVC card, i.e. carrier 102 surface attachment adhesive stickers, to can be attached on other object.
Fig. 8 is that IC chip carrier of the present invention is cell-phone cover, and another IC chip carrier is the embodiment of PVC card.In cell-phone cover 801, comprising carrier 102,802 is mobile phone, and can coordinate like this 103 carrier combinations is an effective IC-card.
