When author carries out push-botton operation on described financial service terminal device, by described bank card near described finance clothes
Business termination, the internal induction module 10 of described bank card card is felt with described financial service terminal device
Should, described bank card realizes signal with described financial service terminal device and is connected.When described bank card realizes and institute
After stating the connection of financial service terminal device signal, operator is by the fingerprint recognition module 20 on described bank card
Carry out fingerprint recognition certification, and by induction module, fingerprint recognition authentication result is sent to described financial service eventually
End device, whether described financial service terminal device is determined deal according to the fingerprint recognition authentication result received continues
Carry out.If fingerprint recognition certification success, then transaction proceeds；If fingerprint recognition authentification failure, then transaction takes
Disappear.
See also shown in Fig. 2 and Fig. 3, described induction module 10 specifically include touch-sensing chip 12,
Field-effect transistor 14, CPU16 and NFC module 18.Described bank card also includes fingerprint recognition module
20 and power module 30.Described fingerprint recognition module 20 includes fingerprint recognition chip 22 and metal edge frame 24.
Described fingerprint recognition chip 22 is for acquisition operations person's finger print information.In the present embodiment, described fingerprint is known
Other chip 22 is capacitance type fingerprint identification chip.Described metal edge frame 24 is used for appearing described fingerprint recognition chip
22 sensing areas, produce charge inducing with described metal edge frame 24 when operator's finger contacts.
Concrete, owing to human body is per se with electric charge, therefore human finger has electrical properties, when human finger touches
When touching fingerprint recognition module metal edge frame, finger is the least to fingerprint recognition module metal edge frame transmission one
Electric current, produces charge inducing.
Human body live finger electrical properties is different with the electrical properties of non-living body finger, when finger departs from human body or human body
After death, the electrical properties of finger immediately begins to weaken, when the electrical properties of finger is attenuated to a certain degree, and fingerprint
Identify that module cannot measure the electrical properties of this finger, i.e. this finger cannot produce with fingerprint recognition module metal edge frame
Charge inducing.
When using other media such as fingerprint film to touch fingerprint recognition module metal edge frame, due to media such as fingerprint films
Not there is electrical properties, so fingerprint recognition module cannot carry out electrical properties measurement to it, therefore cannot be carried out next step
Fingerprint recognition works.
Described touch-sensing chip 12 electrically connects with the metal edge frame 24 of described fingerprint recognition module 20, described
Field-effect transistor 14 is connected with described touch-sensing chip 12, CPU16 and power module 30, described electricity
Source module 30 is connected with described field-effect transistor 14, CPU16, NFC module 18, described CPU16 with
Described fingerprint recognition chip 22, NFC module 18 couple；Described NFC module 18 and described power module 30,
CPU16 connects.
Described touch-sensing chip 12 is for sensing the metal edges of operator's finger and described fingerprint recognition module 20
The charge inducing produced when frame 24 contacts, and when sensing charge inducing to described field-effect transistor 14
Send control signal (controlling signal can be high level signal) to turn on described field-effect transistor 14.Preferably,
Described touch-sensing chip 12 is capacitive touch sensing chip.
After described field-effect transistor 14 receives the control signal that described touch-sensing chip 12 is sent, institute
State field-effect transistor 14 for conducting state, described power module 30 be described fingerprint recognition module 20,
CPU16 and NFC module 18 are powered, thus start described fingerprint recognition module 20 and believe operator's fingerprint
Breath gathers.
Described CPU16 is used for receiving operator's finger print information that described fingerprint recognition chip 22 gathers, and to adopting
Operator's finger print information of collection carries out eigenvalue identification certification with the holder's finger print information prestored, if the behaviour gathered
It is consistent that author's finger print information carries out eigenvalue with the holder's finger print information prestored, then authentication result is successfully；No
Unanimously, then authentication result is unsuccessfully.After finger print information identification certification, described CPU16 is by fingerprint recognition certification
Result is sent to the financial service terminal device with NFC receptor by described NFC module 18, described
Whether financial service terminal device is determined deal according to the fingerprint recognition authentication result received proceeds.If fingerprint
Identification certification success, then transaction proceeds；If fingerprint recognition authentification failure, then cancellation of concluding the business.Therefore, originally
The IC-card with fingerprint recognition authentication function of utility model design can be effectively improved the safety of card, protects
The vital interests of card holder.
Referring to shown in Fig. 4, this utility model additionally provides a kind of IC-card with fingerprint recognition authentication function
Using method.The method includes:
Step S410: operator's finger touches the fingerprint recognition module of the IC-card with fingerprint recognition authentication function,
Whether touch-sensing chip senses operator's finger produces sense when contacting with described fingerprint recognition module metal edge frame
Answer electric charge；
Concrete, operator is by IC-card in time having the termination of NFC receptor, and IC-card card is internal
Induction module senses with termination, and IC-card realizes signal with termination and is connected, and operator passes through IC
Fingerprint recognition module on card carries out fingerprint recognition certification.Operator's finger touches the fingerprint recognition mould on IC-card
The metal edge frame of group, touch-sensing chip senses operator's finger when contacting with fingerprint recognition module metal edge frame is
No generation charge inducing.If touch-sensing chip does not sense operator's finger and fingerprint recognition module metal
The charge inducing that frame produces, then judge that the finger touching fingerprint recognition module is prosthese finger, and IC-card card is internal
Fingerprint recognition module do not start work, now, IC-card can use as a conventional cards, not transaction,
Other functions such as clearing, access and identity validation.If touch-sensing chip senses is to operator's finger and fingerprint
Identify the charge inducing that module metal edge frame produces, then judge that the finger touching fingerprint recognition module is live body hands
Refer to, go to step S420.
Step S420: described touch-sensing chip sends to field-effect transistor and controls signal；
Step S430: described field-effect transistor receives and controls signal, turns on described field-effect transistor, starts
Power module is that described fingerprint recognition module, CPU and NFC module are powered.
