Embodiment 1
[0038] figure 1 It is a structural block diagram of the chip card described in Embodiment 1 of the present invention, as figure 1 As shown, the chip card described in this embodiment includes a fingerprint identification module 120, a central processing unit CPU module 130, a storage module 110, and an output module 140 encapsulated in the card body;
[0039] The storage module 110 is configured to store pre-stored fingerprint information for access by the CPU module 130;
[0040] The fingerprint recognition module 120 is used to collect the fingerprint information of the operator and transmit it to the CPU module 130;
[0041] The CPU module 130 is configured to read the pre-stored fingerprint information from the storage module 110, perform matching judgment on the fingerprint information and the pre-stored fingerprint information, and transmit the judgment result to the output module 140;
[0042] The output module 140 is configured to transmit the interpretation result t...
Embodiment 2
[0049] image 3 It is a structural block diagram of the chip card described in Embodiment 2 of the present invention, as image 3 As shown, the chip card described in this embodiment includes:
[0050] The fingerprint recognition module packaged in the card body, the fingerprint recognition module includes a fingerprint recognition chip 320 (Fingerprinting IC, FPIC), the circuit that uses the fingerprint recognition module to carry out fingerprint recognition verification includes a power management module 360 (PWRcontrol), a fingerprint recognition Module (FPIC), CPU (Central Processing Unit, central processing unit) module 330, NFC (Near Field Communication, near field communication) module 340, AFE (Active Front End, rectification / feedback unit) module 350, EPROM310 (ErasableProgrammableReadOnlyMemory, erasable programmable only read register) and the serial peripheral interface 370 (SPISlave, SerialPeripheralInterface, serial peripheral interface).
[0051] The power m...
Embodiment 3
[0085] Figure 5 It is a flow chart of the chip card-based passwordless authentication method at the chip card side described in Embodiment 3 of the present invention, Figure 6 It is a flow chart of the chip card-based passwordless authentication method on the device for performing financial transactions on the chip card described in Embodiment 3 of the present invention.
[0086] Such as Figure 5 As shown, the chip card-based passwordless authentication method described in this embodiment includes:
[0087] Step S501, the central processing unit CPU module on the chip card body receives the user's fingerprint information from the fingerprint recognition module on the chip card body.
[0088] When a user touches the fingerprint recognition module on the chip card body with a finger, the fingerprint recognition module reads the user's fingerprint information and sends it to the CPU module on the chip card body.
[0089] Step S502, the CPU module reads the pre-stored finger...
