Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be understood that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-2, in an embodiment of the present invention, an IC card with a fingerprint verification function includes a card body 1, where the card body 1 includes an IC card chip 2, a fingerprint sensor 3, a display screen 4, a solar cell panel 5 and a power switch key 6, the display screen 4, the fingerprint sensor 3, the solar cell panel 5 and the power switch key 6 are all embedded on the surface of the card body 1, and the IC card chip 2 is disposed inside the card body 1; the IC card chip 2 comprises an IC card read-write module 11, and the IC card read-write module 11 adopts a chip with the model number of SLE4442 series; the display screen 4 comprises a display module 12, and the display module 12 adopts a chip with model number LC0811-LY series; the solar cell panel 5 comprises a power supply control module 7, the power supply control module 7 adopts a chip with the model of RH6015 series, and a power switch key 6 controls the power on and power off of the solar cell panel 5 through the power supply control module 7; and further, the IC card can be locked by a switch, so that the phenomenon that the display screen is lightened for a long time and the power supply is wasted due to the fact that a card holder passes fingerprint verification through careless touch is avoided.
The solar cell panel 5 is electrically connected with the IC card chip 2, the fingerprint sensor 3, the display screen 4 and the power switch key 6 respectively and used for providing power; IC-card chip 2 carries out electric connection with fingerprint sensor 3 and display screen 4 respectively for the fingerprint verification identity, and with the card in information display on display screen 4.
The fingerprint sensor 3 internally comprises a fingerprint image processing module 8, a fingerprint image acquisition module 9 and a control module 10, the fingerprint image processing module 8 is electrically connected with the fingerprint image acquisition module 9 and the control module 10, and the fingerprint sensor 3 is electrically connected with the IC card chip 2 through the control module 10; the fingerprint image processing module 8 is a DSP processor; the fingerprint image acquisition module 9 is a fingerprint sensor MBF 200; the control module 10 employs a global logic controller of the model EPM3032AE series.
The fingerprint image collecting module 9 collects the identified fingerprint information, the fingerprint image processing module 8 is used for receiving the collected fingerprint information and identifying and authenticating the characteristic value of the collected operator fingerprint information and the prestored card holder fingerprint information, meanwhile, the control module 10 carries out logic control on the information transmission of the fingerprint image processing module 8, when the collected operator fingerprint information is consistent with the prestored card holder fingerprint information in characteristic value, the IC card read-write module 11 reads out the stored data and transmits the data to the display module 12, and therefore the related information stored by the IC card chip 2 is displayed on the display screen 4; when there is no match, the stored data cannot be transmitted to the display module 12, i.e., no information can be displayed.
