In order to improve the general applicability of read write line, read write line should be equipped with 1 at least and meet the PSAM card slot 27 that finance requires, be not equipped with or do not have the PSAM slot of free time at financial terminal, and during some IC-card application need PSAM card (needing the PSAM card) as electronic wallet application, the PSAM slot that can utilize read write line to be equipped with is placed the PSAM card, but preferentially use the own PSAM slot of financial terminal, the data rate of terminal and PSAM card is very fast like this.And described PSAM card slot is with low cost, can't significantly increase the equipment cost of read write line.
Preferably, described noncontact IC card read/write device is integrated in each functional module on the chip, and this built-in chip adopts non-programmable pattern.Non-programmable formula read write line is meant that read write line itself does not possess secondary program development ability, can only receive the instruction that the equipment (as POS, PC) that joins with it sends, and return corresponding operating result.For non-programmable formula read write line, all non-contact IC card service logics are all finished by being attached thereto the terminal device that connects.And formula read write line able to programme is meant that read write line itself can pass through the secondary program development, to realize the contactless IC card read/write equipment of part or all of non-contact IC card service logic.
Circumscribed noncontact financial IC card read write line interface modes in the present embodiment adopts the reason of non-programmable pattern that following 3 points are arranged: first, financial terminal on present stage market has had the processing power of IC-card business, only needs an expansion non-contact interface to get final product; The second, non-programmable read write line is with low cost, is applicable to the requirement in contactless application start popularization stage; And read write line able to programme is with high costs, is unfavorable for the popularization of contactless application; The 3rd; the mode of external non-contact reader-writer realizes contactless application on financial terminal; it is a kind of protection to existing finance device investment; development along with technology; the product that finance device itself carries contactless module has appearred; so the development space of programmable read write line is also little, is not mainstream applications.
The hardware module that circumscribed noncontact financial IC card read write line 11 more than has been described constitutes, and below in conjunction with terminal applies module 12 that is installed on financial terminal and non-contact IC card 13 the internal work flow process of read write line 11 is described, and is as follows:
Financial terminal at first sends a command packet to read write line hard core control device by RS232 (or USB) communication interface, is sent completely the reply data bag of back wait from read write line hard core control device.Correctly receive the command packet of financial terminal transmission when read write line hard core control device after, resolve this order by the hard core control device, card is operated by radio-frequency module and antenna as not needing, then handled this order and respond the financial terminal reply data by RS232 (or USB) communication interface; By radio-frequency module and antenna card is operated if desired, is then carried out communication with card, obtain the response data of card after, the hard core control device sends reply data by RS232 (or USB) communication interface to financial terminal.
In said process, if financial terminal fails to receive the reply data bag that read write line is correct that then financial terminal finishes this data communication in the maximum duration of regulation, and the prompting error message.In like manner, read write line is during by built-in clock electricity frequency meter, if read write line is not received the response data of card in the maximum duration of regulation, then read write line hard core control device should be replied to the operation overtime that financial terminal returns card.
At the inner implementation of above-mentioned read write line, the total shutdown of non-programmable formula contactless IC card read/write device, idle, the transition state when activating conversion between 7 kinds of stationary states such as card, transaction processing, Transaction Success, Fail Transaction, unknown state and each state.With reference to Fig. 3, be the state exchange and the corresponding operating synoptic diagram of described read write line, state conversion process is as follows:
By hard core control device module controls, be to send signal to power management module when running into power-on command at first, power management module receives that the back starts relevant each the module working power of complete machine.Read write line hard core control device module continues the initialization start, if start is normal, then constantly circulation of use and management instruction enters idle condition; If run into outage midway, then enter off-mode.At this moment radio-frequency module is by day card (TYPEA or TYPEB) of ray examination different agreement, adopt polling mechanism to send incessantly in the electromagnetic wave signal detection effective range and have or not effective proximity card, and be the request signal that alternately sends category-A type card (TYPEA) and category-B type card (TYPEB), the order of A type card and Type B card and response mutual interference mutually.When effective card entered active zone, radio-frequency module provided the concurrent card feed activation instruction of energy that card is activated with inductive coupling to the proximity card.If card is activated, then enter the activation card mode; If when running into software reset that overtime instruction, suspended market order or hard core control device module that the clock electricity takes place frequently out send and instructing, then enter idle condition immediately, and to the memory headroom initialization of storage relevant information; If run into outage midway, then enter off-mode.
After entering the activation card mode, can begin transaction processing (may need the PSAM card together to participate in business, just need the PSAM card to participate in) as electronic wallet application, this moment, read write line entered the transaction processing state.Terminal sends trading instruction by read write line to card, and card is made response and response data is transferred to terminal with the form of communication data packets by read write line, carries out transaction processing by terminal.May carrying out repeatedly alternately of terminal and card.If run into outage midway, then read write line enters off-mode.If the terminal transaction success, then read write line enters the Transaction Success state; If terminal transaction failure, then terminal is carried out corresponding Fail Transaction processing and read write line enters the Fail Transaction state.And Transaction Success state and Fail Transaction state can enter idle condition through software reset's instruction, wait for cycle of states next time, also may enter off-mode because of outage.In addition, during unknown state outside read write line runs into above-mentioned state, hard core control device module can be sent software reset's instruction can enter idle condition, or meets outage and enter off-mode.
In the internal work and state conversion process of read write line, under the situation that is used for transaction such as electronic wallet application, no matter the PSAM card slot is built into financial terminal or is provided by read write line, all relates to the processing of PSAM card.The PSAM card will be in the following manner carries out safety certification to the data exchange process of PSAM card and non-contact IC card:
At first send Transaction Information to the PSAM card by terminal, the PSAM card generates message authentication code MAC1 according to this Transaction Information and terminal is given in loopback, the Transaction Information that the terminal transmission comprises MAC1 is to the stored value card IC-card, and IC-card authenticates its MAC1, the legitimacy of authentication authorization and accounting PSAM card; If authentication is passed through, reply and generate this message authentication code MAC2 that replys by IC-card generation respective transaction and send to terminal in the lump, terminal utilizes the PSAM card that the MAC2 that receives is authenticated, the legitimacy of this IC-card of authentication authorization and accounting, and authentication result sent to terminal, thereby realize PSAM card and IC-card user's two-way authentication, prevent that transaction data from being distorted, guarantee the validity of Transaction Information.
More than be explanation, will be elaborated to terminal applies module 12 below noncontact IC card read/write device 11.As previously mentioned, terminal applies module 12 is installed on the financial terminal equipment and uses as the corresponding software module of read write line 11.With reference to Fig. 4, be the operational flowchart of terminal applies module 12.This operating process provides a suggestive method for financial terminal to the operation of read write line, and the terminal that may occur and the abnormal conditions between the read write line are handled is described.Operating process is described as follows:
Step 407 after system finishes user's card abort process or following electric process, enters and handles and demonstration transaction results process, then enters end process after finishing.
In above-mentioned flow process, relate to the anti-processing capacity of pulling out of terminal, this function is the preferred setting of present embodiment.Prevent pulling out handling and be meant in consumer sale processes such as stored value card, card breaks away from the magnetic field induction zone of read write line suddenly, cause read write line can not receive the response of card, read write line should be responded the terminal error code and reply for can not receive card, terminal should remind the holder to be reentered into card, and promptly terminal enters the anti-treatment state that pulls out.
Enter anti-pull out treatment state after, if the Attended mode terminal should stop to accept other cards transaction, wait card and insert again or return the magnetic field induction district, prevent pulling out treatment scheme, unless transaction processing successfully, or cashier's state reset processing of transacting business.If the unmanned terminal, enter anti-pull out treatment state after, should not influence the transaction processing of follow-up other cards, but need keep the respective transaction data of extracting card, in order to interrupting the recovery of transaction in certain zone.Terminal can be provided with counter, after follow-up other card transaction processing surpass preset number of times anti-and pull out affirmation, cancels the anti-treatment state that pulls out of this card automatically, in order to avoid influence the terminal transaction processing speed.
Above-mentionedly anti-pull out the affirmation process and be: terminal enter anti-pull out treatment state after, all will check card issuer's sign and application sequence number to every card of subsequent treatment, with the card of affirmation insertion and the card extracted previously the same card whether.If the same card, terminal is sent transaction and is recovered order.The TAC instruction if card returns MAC, terminal is promptly finished transaction processing; If MAC illustrates that then the remaining sum in the IC-card is not modified or/and TAC can't loopback, transaction can restart with suitable initialization command.
At the non-contact IC card read-write system that Fig. 1 provides, the present invention also provides the non-contact IC card identification method of using this system embodiment, and the identifying of this method is as follows:
At first, the terminal applies module judges whether read write line connects normal, if normal, then continues to judge the read write line type; Judge then whether non-contact IC card activates, if then read user profile in the card by read write line; After having read subscriber card information, need to judge whether the anti-processing of pulling out, if then enter the anti-processing of pulling out; If not, then enter the transaction processing process.
The transaction processing process is as follows: the terminal applies module sends order by the communication interface of read write line to read write line hard core control device; Read write line hard core control device is resolved described order, if do not need non-contact IC card is operated, then directly by communication interface to terminal applies module echo reply data; If desired, then carry out communication, and the reply data of non-contact IC card is returned to the terminal applies module by communication interface by radio-frequency module and antenna and non-contact IC card.
Preferably, if read write line is not received the reply data of non-contact IC card in preset time, then read write line hard core control device returns to the terminal applies module by communication interface that card is overtime replys.If the terminal applies module is not received the reply data of read write line in preset time, then the terminal applies module finishes this communication, and the prompting error message.
The part that does not describe in detail in the said method can be considered for length referring to the relevant portion of Fig. 1-system shown in Figure 4, is not described in detail in this.
