Description
Technical field
The present invention relates to field of intelligent cards, particularly relate to a kind of realize the system and method that double-interface smart card real-time transaction data information shows.
Background technology
Nowadays, contact intelligent card (lower abbreviation contacts card) has obtained universal application in daily life.Contact card universal during, gradually it is found that the drawback of many: be stuck on read write line the abrasion that often plug causes and cause loose contact, thus cause data transmission fault, and the abrasion between card and read write line also substantially reduces the service life of card and read write line；It addition, the communication speed of contact card is relatively low, the action adding plug-in card is delayed, and causes each transaction to need the wait of long period.
In order to solve these problems, contact type intelligent card (under be called for short non-contact card) arises at the historic moment.The advantage of non-contact card is apparent from: it carries out communication by radio wave and read-write equipment, without exposed contact, with between read write line also mechanical contact, reliability and high life；Its communication speed, can be from any direction and read-write equipment communication in the range of certain distance higher than contact card, so that operating more convenient, quick.Therefore, non-contact card instead of contact card in a lot of occasions, increasing in the share shared by card market.
Along with technology and the development of application, the application of non-contact card based on RFID REID is more and more extensive, and function the most from strength to strength, also occurs in that the double-interface card that contact type intelligent card and contact intelligent card combine in application.Double-interface card is to be closed chip coil by layer of PVC to form, based on single-chip, integrate the smart card of contact and non-contact interface, it has two operation interfaces, access to chip, can be by the contact of the way of contact, it is also possible to by separated by a distance, carry out access chip with RF-wise by RF interface, can carry out identical operation by contact interface and non-contact interface.Two different standards are followed at two interfaces respectively, and contact interface meets ISO/IEC 7816；Noncontact meets ISO/IEC 14443.Same microprocessor, operating system and EEPROM are shared in both interfaces, namely, double-interface smart card card includes a microprocessor chip and an aerial coil being connected with microprocessor, the electromagnetic field produced by read write line provides energy, realizes energy supply by RF-wise and data are transmitted.
Double-interface card sheet can support multiple application, and a card can be with integrated multiple different application, conglomerate hair fastener simultaneously, in application flexibly, conveniently；And according to different application condition and requirement, can optionally use contact or non-contact transaction mode, cut operating costs.It is big that double-interface card sheet is applicable to trading volume, and exchange hour is short, and in the process of exchange use environment without waiting, and because its facility are totally-enclosed, collapse resistance and capacity of resisting disturbance are strong, it is adaptable to harsh environments and self-service consumption place；Double-interface smart card has card anti-collision mechanism, it is allowed to multiple cards simultaneously enter trading post, and completely compatible with conventional contact equipment, can the most directly use.
Double-interface card has ruggedness and an ease of use of non-contact card, but RFID non-contact card existing defects: when card curved transitions, card easily lost efficacy because the fracture of coil solder joint；The communication easily failure by environmental disturbances in some occasions；Encryption method is relatively simple, and safety is less than contact card etc..
The safety problem of double-interface card system, is caused by the safety guarantee link of three different levels, and one is the safe practice that electronic tag manufactures；Two is the physical security technology of chip, such as anti-illegal read-write, anti-software track etc.: three is the communication security techniques of card, such as the data cutout of information communication process and invalid data communication etc..These three aspect is collectively forming the security system of electronic tag, affects electronic tag from producing to the safety used.
In order to the manufacture safety problem of electronic tag is analyzed, electronic tag life cycle can be divided into four-stage: manufacture, individualize, apply, destroy.In order to ensure the safety of electronic tag, the wooden fork limit that control chip in electronic tag reads write-in functions progressively limits.Such as after the fabrication stage terminates and individualized, one fuse of fusing, progressively strengthens the restriction to electronic tag respectively.
It addition, because electronic tag does not has exposed electric interfaces, wirelessly carry out with the data exchange of the equipment of identification, there is great motility and versatility.But while bringing great convenience to user, owing to the wave point of electronic tag opens to any user in recognizable distance range, and may be conducted interviews by other identification equipment, so causing opportunity to forcible entry in the case of electronic tag holder has no to perceive.
In the case of the competition of RFID industrial market, the whole world is fiercer, the smart card of application RFID develops to higher level direction, such as convert to multi-function intelligent card from single function smart card, convert to multisystem smart card from the smart card of single system, banking system is turned to apply by non-banking system, by civilian turn to military, by LAN to the Internet migration etc..
Along with these develop, user is more and more higher to the requirement of the application function of smart card, it is desirable to smart card can provide increasing application function, to meet people safety, convenience and diversified demand in use.Especially as the smart card of electronic money, on it, record has a large amount of important information, and optical safety is not extremely important, and as the application system of the electronic transaction smart card such as bank, security, social security, needs in time to the record of client feedback transaction.
But in current application of IC cards system, the display of transaction data is only capable of displaying in Card Reader end and application system, substantial amounts of data are stored in in card application system, in the system of bank；And it is only capable of displaying the current data concluded the business, as user needs more transaction data, then need additionally to printing with card application system application or downloading.Therefore, user is generally not capable of obtaining timely, enough pertinent transaction information.
Summary of the invention
Deficiency based on existing application of IC cards system, the invention provides and a kind of realize the system and method that double-interface smart card real-time transaction data information shows, to solve existing application of IC cards system to intelligent card subscriber transaction data information in process of exchange to the most transparent problem of user, and solve information security issue further.
