The POS machine method of commerce of the both hands machine of confrontational flow process and dynamic encryption
[technical field]
The present invention relates to utilize the financial settlement field of the communication field and the bank card of mobile phone.
[background technology]
In present society, the POS machine has been widely used in bank card clearing field, provides great convenience to people.
The development of mechanics of communication now popularizes as mobile phone that in time obtain and send that various information provide may for people.
[summary of the invention]
Social now, after swiping the card on the POS machine, POS machine master's the bank of deposit generally delivered to payment information earlier by the POS machine, it is card-receiving bank, by card-receiving bank payment information is forwarded to issuing bank behind meta networks such as Unionpay again, or directly payment information is forwarded to issuing bank, will confirm that to payment payment information returns by former road by issuing bank behind the validation of information.The method length not only consuming time, and need through complicated encryption technology, it is higher to encrypt cost.Therefore, invent and a kind ofly new can accelerate the safe and reliable again bank card transaction method of bank card business dealing speed, just seem very necessary.The present invention is exactly in order to reach above purpose.
The present invention is based on the development of The present computer technology and modern communications technology.
Indication bank can be business bank, urban credit cooperative, rural credit cooperative, postal saving or distribution and the specialized company that manages bank card in this method, bank card refers to that the specialized bank blocks the card that can carry out financial transaction of exempted dealers's distribution, can be debit card, credit card and credit card; In the method, special POS machine is a transaction terminal that has a random code generator C and two mobile phone A and mobile phone B; Mobile phone A and mobile phone B can be the mobile phones of identical standard network, are the mobile phone of cdma network or the mobile phone of GSM network as mobile phone A and mobile phone B; Mobile phone A and mobile phone B also can be the mobile phones of various criterion network, belong to the mobile phone of cdma network or the mobile phone of GSM network respectively as mobile phone A and mobile phone B; Random code generator C can be pseudo-noise code generator (Pseudo Random Number Generator), produces different dynamic passwords at random when being used for each bank card business dealing, to replace existing traditional approach transaction is encrypted.
Method of the present invention, the POS machine method of commerce of the both hands machine of promptly a kind of confrontational flow process and dynamic encryption, wherein, special POS machine is a transaction terminal that has a random code generator C and two mobile phone A and mobile phone B, mainly comprises the steps:
A, bank card chief commander bank card are swiped the card on special POS machine;
B, bank card on special POS machine, swipe the card the payment information that produces together with special POS machine with
The dynamic password that machine code generator C produces is sent by the mobile phone A on the special POS machine
Issuing bank to bank card;
C, issuing bank confirm payment after to the payment credit verification, will confirm payment information and described
Dynamic password is with wired or wireless transmission means, or through other meta networks, is sent to
Special POS machine master's the bank of deposit, i.e. card-receiving bank;
Accept money information and described dynamic password are forwarded to really with issuing bank for d, card-receiving bank
Another mobile phone B on the special POS machine;
After payment information that produces in e, the special POS machine described affirmation payment information that forwarding comes to card-receiving bank and dynamic password and the step (b) and dynamic password are checked, carry out bank card business dealing;

[description of drawings]
Fig. 1 is the key diagram of method step of the present invention.
[embodiment]
The present invention is further illustrated below by drawings and Examples.
The step of process description the inventive method of Figure of description, in the present embodiment, mobile phone A belongs to the cdma network mobile phone, and mobile phone B belongs to GSM network mobile phone.
A, for example bank card master Huang Jinfu are held Shenzhen agricultural bank card 955,991,234,567,890 5000 yuan of bankcard consumption RMB on the special POS machine in starlight market;
B, bank card 955991234567890 payment information that produces of swiping the card on special POS machine (contains bank's card number 955991234567890, password 123456,5000 yuan of amount of money RMB etc.) dynamic password that produces at random together with special POS machine random code generator C sends to Shenzhen agricultural bank of issuing bank of bank card as 888888 by the cdma network mobile phone A 13302966788 on the special POS machine; In this step, the random dynamic puzzle that the each exchange of random code generator C produces can be not identical, in case divulge a secret; As this transaction dynamic password is 123456, and next time transaction dynamic password may be 654321 or the like; Special POS machine also can send own code, as 955,550,755 1888, so that issuing bank's identification;
C, Shenzhen agricultural bank of issuing bank confirm payment after to the payment credit verification, to confirm that then payment information and former dynamic password 888888 are with wired or wireless transmission means, or through other meta networks, as Unionpay's network, be sent to the bank of deposit in special POS machine primary light market, be card-receiving bank, as Shenzhen China Merchants Bank;
Accept money information and described dynamic password 888888 are forwarded to another GSM network mobile phone B 13902966788 on the special POS machine really with issuing bank for d, card-receiving bank Shenzhen China Merchants Bank;
After e, the special POS machine described affirmation payment information that forwarding comes to card-receiving bank and dynamic password 888888 are checked with former payment information and dynamic password 888888, carry out bank card business dealing; As allow bank card master Huang Jinfu to consume 5000 yuan of RMB;
F, Shenzhen agricultural bank of issuing bank answer 5000 yuan of fund RMB to the special POS machine primary light market account of card-receiving bank Shenzhen China Merchants Bank from bank card master Huang Jinfu bank card account 955991234567890 phase inversions.
In the method, mobile phone A and mobile phone B also can be the mobile phones of same standard network, are the mobile phone of cdma network or the mobile phone of GSM network as mobile phone A and mobile phone B, and in this case, the step of the inventive method is constant.
Because this method adopts two mobile phones to receive and send messages and uses random code generator C to produce random dynamic puzzle, and the level security of bank card business dealing is improved greatly.
