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 the Separable combination band, comprises i.e. 104,108 signal antennas that are IC chip 104 of IC chip 1 in carrier 102, comprise i.e. 105,107 signal antennas that are IC chip 105 of IC chip 2 in carrier 103.Carrier 102 and 103 can be combined as to an effective IC-card with plane form by Separable combination band 106, at ordinary times by carrier 102 and within 103 minutes, open the 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 the 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 the lamination form.
IC chip carrier of the present invention is not limited to traditional IC-card sheet, it can be other any form, as the 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 when the card reader, at first reads the identifying code of IC1, by judgement, if failure finish authentication, if success read the identifying code of IC2, by judgement, if failure finish authentication, if success carry out read-write operation would complete authentication and operation.
Fig. 4 is the schematic diagram that IC-card radio frequency powered of the present invention is regulated start-up time by the 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 the RC circuit, thereby control the work start-up time of IC chip, reach the purpose of the sequence starting of two or several IC chips.In Fig. 4, coil L and capacitor C 1 form the LC resonant circuit, it is the 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 the 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 provides working power for the IC chip.This shows that R1 and C2 or R2 and C2 form the RC circuit, the time constant of RC circuit is in the situation that capacitance values is identical can change by resistance, in Fig. 4 of the present invention, the resistance of current-limiting resistance R1 and R2 is different, in order 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 the embodiment that the present invention adopts key chain to be the IC1 carrier.In figure, carrier 102 and carrier 103 are separable, and an aperture 501 is arranged on carrier 102, by aperture 501, can wear and hang on key chain or on any lanyard, like this can printed patterns on carrier 103, and carrier 102 can safekeeping.
The carrier that Fig. 6 is 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 combined that matches with carrier 102 is the 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 the 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, in order to can be attached on other object.
Fig. 8 is that IC chip carrier of the present invention is cell-phone cover, the embodiment that another IC chip carrier is the PVC card.Comprising carrier 102,802 in cell-phone cover 801 is mobile phone, and can coordinate like this 103 carrier combinations is an effective IC-card.
