By means of the portability of mobile phone, Mobile banking can provide 3A (Anytime, Anywhere, bank service Anywhere) for the user.Compare traditional Internet bank, Mobile banking is more convenient, to user's more attractive, has bright development prospect, and a key factor of restriction Mobile banking development is fail safe.Because concerning user's property safety, even the cellphone subscriber hopes at some in particular cases to lose like mobile phone, when account password was cracked rogue programs such as perhaps in mobile phone, there being virus, Mobile banking is safety still.
Different with personal computer, in field of mobile phones, there is not unified USB interface, even identical manufacturer is also different for its data interaction interface of mobile phone of different model.Therefore, can't utilize the U shield to solve the safety problem of Mobile banking.
The bank card payment is a kind of mode that replacement is paid in cash.Need not to worry to receive counterfeit money because the user has removed inconvenience, the businessman of carrying cash from, the bank card payment receives the welcome of user and businessman very much.
But the prerequisite of use magnetic stripe card, following contact intelligent card and the RFID contact type intelligent card bankcard consumption of IS0/IEC7816 international standard is that corresponding POS machine need be equipped with corresponding read-write equipment.Though by the end of the year 2009, China networking POS machine quantity has reached 240.83 ten thousand, POS machine coverage rate is still very low, and the medium and small trade company of One's name is legion still is not equipped with the POS machine.Consider that mobile phone is very universal, a kind of feasible method is that POS machine program is installed on mobile phone, makes mobile phone serve as the POS machine and uses, and can solve the low problem of POS machine coverage rate in the bankcard consumption thus.
The utility model content
The purpose of the utility model is to provide a kind of Electronic Finance equipment, can on same electronic equipment, realize earphone shield and two kinds of functions of earphone bank card, can effectively solve safety problem and the low problem of POS machine coverage rate in the mobile-phone payment.
The purpose of the utility model is to realize through following technical scheme:
A kind of earphone shield with payment function; Comprise microprocessor, battery and the memory that links to each other with microprocessor, safety chip; Said microprocessor is connected with modulator-demodulator and earphone interface in turn; Said modulator-demodulator is realized the conversion of simulated audio signal and digital signal, and said earphone interface is used for connecting with mobile phone; Said microprocessor periphery also is connected with fingerprint identification module, miniature keyboard, liquid crystal micro display and mode selector switch.
Special, said battery adopts rechargeable battery, and it links to each other with USB interface through contactor.
Special, said earphone interface is that diameter is headset plug/jack of 3.5mm or 2.5mm.
The described earphone shield with payment function of the utility model: it adopts the earphone interface that generally adopts at present on the mobile phone as data transmission interface, almost can be used for all mobile phones, for mobile-phone payment provides a kind of mobile phone shield, guarantees transaction security; Cooperate fingerprint identification module, miniature keyboard, liquid crystal micro display simultaneously; Utilize handset port to join, can have bank card functionality, realize the mobile-phone payment function with the mobile phone that POS machine program is installed; Enlarge the scope that mobile-phone payment is used, reduced the difficulty that mobile-phone payment is used.
Description of drawings
According to accompanying drawing and embodiment the utility model is done further explain below.
Fig. 1 is the said composition structural representation with earphone shield of payment function of the utility model.
Among the figure:
1, microprocessor; 2, memory; 3, safety chip; 4, earphone interface; 5, modulator-demodulator; 6, fingerprint identification module; 7, rechargeable battery; 8, contactor; 9, USB interface; 10, liquid crystal micro display; 11, miniature keyboard; 12, mode selector switch.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer, do to describe in detail further below in conjunction with accompanying drawing 1.
This earphone shield with payment function comprises microprocessor 1, memory 2, safety chip 3, earphone interface 4, modulator-demodulator 5, fingerprint identification module 6, rechargeable battery 7, contactor 8, USB interface 9, liquid crystal micro display 10, miniature keyboard 11 and mode selector switch 12.Microprocessor 1 links to each other with memory 2, safety chip 3, modulator-demodulator 5, fingerprint identification module 6, rechargeable battery 7, liquid crystal micro display 10, miniature keyboard 11, mode selector switch 12.
The identification that fingerprint identification module 6 is realized user fingerprints, thus subscriber authentication accomplished.1 power supply of 7 pairs of microprocessors of rechargeable battery.Memory 2 storage users' various keys and digital certificate, safety chip 3 is accomplished safety related functions, realizes that simultaneously data encryption and deciphering, digital signature generate and authentication function.The various keys that comprise private key for user are only deposited in the safety chip 3, can't derive.Fingerprint identification module 6 is used for discerning fingerprint.When initialization, need first typing user fingerprints, when using the earphone shield, need to confirm user identity through fingerprint recognition, have only the user to pass through fingerprint recognition after, the earphone shield is just worked; Result through fingerprint recognition is presented on the liquid crystal micro display 10.The display screen of liquid crystal micro display 10 can only show delegation's information, and miniature keyboard 11 total upper and lower, left and right, definite, cancellation six press keys can be used for representing six kinds of operations.When the amount of information that on liquid crystal micro display 11, shows surpassed the screen size of display, the upper and lower, left and right button that can operate miniature keyboard showed complete information.When the user need confirm and when cancelling, uses and confirm and the cancellation button some operation.Mode selector switch 12 is buttons; Be used for switching the mode of operation of earphone shield, when the user pressed the button, the earphone shield switched to the bank card mode of operation; Through joining with the mobile phone that POS machine program is installed; Can have bank card functionality, realize the mobile-phone payment function, otherwise be in earphone shield mode of operation.
