Embodiment

Hereinafter, will describe the utility model in detail.

One preferred embodiment of a kind of e_payment cipher 100 of the present utility model, as shown in Figure 1, comprise display unit 110, keyboard 120, storer 130, communication interface 140, payment cipher special chip 150, and central processing unit 160, each parts is connected with described central processing unit 160 communications, and be subjected to the control of described central processing unit 160, the driver of each parts is installed in this central processing unit in advance; Other has a modulation-demodulation device 170, also be connected with described central processing unit 160 communications, and on this central processing unit 160, driver being installed, described e_payment cipher can connect destination server by the internet based on different communications protocol under its control.The circuit of described modulation-demodulation device 170 as shown in Figure 2, mainly is to be made of a Modem chip 171, and this chip is connected with central processing unit 160 communications, and other are used for the processing and amplifying signal for a plurality of transistors; This modulation-demodulation device 170 can internal or external independent one-tenth machine, and its function is the same.

The modulation-demodulation device 170 of e_payment cipher 100 of the present utility model can also be without the internet, based on different communications protocol, directly connect described destination server, enter the server of certain bank, provide respective service but prerequisite is this bank as the phone dialing mode that adopts PSTN.

In e_payment cipher of the present utility model, display unit 110 is dot matrix LCDs, so that be subjected to the control of described central processing unit to show any literal or figure; Can also be provided with a touch-screen 180 on this e_payment cipher 100, particularly, can have unified profile with described matrix liquid-crystal display screen; Described storer 130 also comprises flash memory 131 and dynamic storage 132, and particularly, described flash memory 131 has the 4M size, and dynamic storage 132 has the 8M size, so that this e_payment cipher deal with data and instruction running when directly networking separately; Described central processing unit can be 32 a processor.

The electronic payment secret code special chip 150 that the control of described e_payment cipher produces payment cipher is general SSX10-B chip; Described keyboard 120 is 5 * 4 arrangements, but is not limited to this arrangement mode.

Described e_payment cipher 100, also have a plurality of communication interfaces, particularly, can be the serial ports RS-232 interface, therefore, e_payment cipher of the present utility model can utilize the computing machine of one of them communication interface and networking to link to each other equally and link the internet, certainly, also connects telephone wire by communication interface during external modulation-demodulation device and realizes.

Need to prove, the networking of e_payment cipher of the present utility model is to adopt Internet technology, dial in the server of ISP service provider by the user after, can connect different banks simultaneously, as using web browser, can also realize the online download and upgrade of software and support Email, and the professional item of some other non-financial institution, as the form of industrial and commercial and the tax, notice and file online exchange etc. newly, only need in advance in storer the software platform support of setting operation program and corresponding mechanism get final product.

E_payment cipher of the present utility model, the step of realization networking, as shown in Figure 3, usually realize by preloaded software, 1. as fail to be communicated with under user's operation, described central processing unit is to the order of described modulation-demodulation device Sending dialled number: " atdt "+web-enabled phone number, and wait for the return data that receives Modem:, then need determine whether and to dial again, again dial as need, repeat above-mentioned dialup networking process, otherwise, withdraw from, show the networking failure; 2. as receiving service down distributing successful connection information, the success of expression Connection Service device.Behind the success Connection Service device, the user imports online account number and password and uploads onto the server, after server authentication online account number and password are correct, return the successful information of networking, afterwards, can carry out repeatedly as required and upload data p1 or receive data p2, carry out the transmission of data, send instruction until the user and carry out disconnection network operation p3.

1, data upload p1:

When request data package need be uploaded, need type according to request of data, as html file request, ftp file transmission, POP3 transmission requests or other protocol format requests, adopt the corresponding protocol form to package respectively, to organize data that good protocol data bag transmits as need again by behind the ICP/IP protocol group bag, once more the ICP/IP protocol packet is packaged by ppp protocol, finally send modulation-demodulation device, be sent to destination server by modulation-demodulation device.

2, receive data p2:

Just the process with above-mentioned transmission data is opposite for the process of reception data, receive packet by modulation-demodulation device from destination server by ppp protocol, decomposite the packet of ICP/IP protocol form, the protocol type of judgment data bag then, as HTTP, FTP, POP3 or extended formatting, disassemble out packet by corresponding group of packet protocol again, the data storing that finally obtains is pending in the data processing buffer zone etc.

3, disconnect network p3:

When the user need be hung up network, need to send cut-off signal: stop to send 2 seconds of data to modulation-demodulation device, then will " +++" signal and on-hook order " ATH " deliver to modulation-demodulation device, modulation-demodulation device is received the instruction back and is stopped networking, and the return result.

Internet technology has fully been used in the networking of e_payment cipher of the present utility model, only needs bank that server is set, and enterprise does not need the configure calculation machine, can be achieved as follows function:

1), current account balance inquiry: the client can be close by E-Payment of the present utility model After the networking of code device, call the relevant information of bank server, the current remaining sum of inquiring about own account.

2), account's account statement inquiry: the client can pass through electronic payment secret code of the present utility model After the device networking, call the relevant information of bank server, consult any period of own account Receipt and payment information and check sheet.

3), online ticket payment: the client can pass through e_payment cipher of the present utility model After the networking, no longer need bill is delivered to bank, just can send to bank the electricity of ticket payment Sub-information realizes finishing of payment, certainly wherein also has security measures.

Above-mentioned functions is not limitation of the utility model, and this depends on, and bank server provides The software support of service and e_payment cipher is owing to set up modulation-demodulation device, this reality Do not need computer supported with novel e_payment cipher, the independent internet of directly linking, To be invention core of the present utility model, therefore, for those of ordinary skills, root Replace or distortion according to any being equal to that technical conceive of the present utility model is done, all should belong to this reality Protection domain with novel appended claim.
