Description
Technical field
The present invention relates to field of intelligent cards, relate in particular to a kind of system and method for realizing that double-interface smart card real-time transaction data information shows.
Background technology
Nowadays, contact intelligent card (being called for short the contact card down) has obtained general application in daily life.In the universal process of contact card, many drawbacks have been found gradually: be stuck in the wearing and tearing that frequent plug causes on the read write line and cause loose contact, thereby cause data transmission fault, and the serviceable life of card and read write line has also been shortened in the wearing and tearing between card and the read write line greatly; In addition, the communication speed of contact card is lower, adds the action of plug-in card and incurs loss through delay, and causes each transaction to need the wait of long period.
In order to address these problems, contact type intelligent card (being called for short non-contact card down) arises at the historic moment.The advantage of non-contact card is conspicuous: it carries out communication by radiowave and read-write equipment, does not have exposed contact, mechanically contacts reliability and high life with also not having between read write line; Its communication speed is higher than contact card, can be in the certain distance scope from any direction and read-write equipment communication, thereby make operate more convenient, quick.Therefore, non-contact card has been substituted the contact card in a lot of occasions, and is increasing in the share that card market is shared.
Along with technology and application and development, based on the application of the non-contact card of RFID REID more and more widely, function the double-interface card of contact type intelligent card and contact intelligent card combination also occurred also from strength to strength in the application.Double-interface card is to be formed by the laminated chip coil of PVC, based on single-chip, collection contact and non-contact interface are the smart card of one, it has two operation interfaces, to the visit of chip, can also can pass through separated by a distance by the contact of the way of contact, visit chip with RF-wise by the RF interface, can carry out identical operations by contact interface and noncontact 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 these two kinds of interfaces, also be, the double-interface smart card card comprises a microprocessor chip and an aerial coil that links to each other with microprocessor, the electromagnetic field that is produced by read write line provides energy, realizes energy supply and data transmission by RF-wise.
The double-interface card sheet can be supported multiple application, and card can integrated a plurality of different application, conglomerate hair fastener simultaneously, and is flexible applications in, make things convenient for; And according to different application condition and requirement, can choose wantonly and adopt contact or non-contact transaction mode, cut operating costs.The double-interface card sheet is applicable to that trading volume is big, and exchange hour is short, in the environment for use that process of exchange need not to wait, and totally-enclosed because of its facility, anti-destruction and antijamming capability are strong, are applicable to abominable working environment and self-service consumption place; Double-interface smart card has the card anti-collision mechanism, allows many cards to enter trading post simultaneously, and compatible fully with traditional contact equipment, can directly use thereon.
Double-interface card has the durability and the ease of use of non-contact card, but there is defective in the RFID non-contact card: when the card curved transitions, card lost efficacy because of the fracture of coil solder joint easily; Be subjected to environmental interference easily and fail in the communication of some occasions; Encryption method is simpler, and security is lower than contact card etc.
The safety problem of double-interface card system is caused by the safety guarantee link of three different levels, and the one, the safety technique that electronic tag is made; The 2nd, the physical security technology of chip, as anti-illegal read-write, anti-software track etc.: the 3rd, the communication security technology of card is as the data cutout of information communication process and invalid data communication etc.These three aspects form the security system of electronic tag jointly, influence electronic tag from producing to the safety of using.
Analyze for manufacturing safety problem, the electronic tag life cycle can be divided into four-stage: make, individualize, use, destroy electronic tag.In order to guarantee the safety of electronic tag, the wooden fork limit of reading write-in functions of control chip in the electronic tag is progressively limited.Such as after fabrication phase end and individualized finishing, the fuse that fuses is respectively progressively strengthened the restriction to electronic tag.
In addition,, carry out with wireless mode, have great dirigibility and versatility with the exchanges data of identification equipment because electronic tag does not have exposed electric interfaces.But when bringing great convenience to the user, because but the wave point of electronic tag is opened to the Any user in the decipherment distance scope, and under the situation that the electronic tag holder has no to perceive, may be conducted interviews, so cause opportunity to forcible entry by other identification equipments.
Compete under the fierce more situation in global RFID industrial market, the smart card of applying RFID electronic tag develops to higher level direction, such as transforming to multi-function intelligent card from single function smart card, transform to the multisystem smart card from the smart card of single system, turn to banking system to use by the non-banking system, by civilian turn to military, by LAN (Local Area Network) to the Internet migration etc.
Along with these development, the user is also more and more higher to the requirement of the application function of smart card, wishes that smart card can provide increasing application function, to satisfy people's security, convenience and diversified demand in use.Especially as the smart card of electronic money, record a large amount of important informations on it, optical safety is not extremely important, and as the application system of electronic transaction smart cards such as bank, security, social security, needs in time the record to client's feedback trading.
But in the present application of IC cards system, the demonstration of transaction data only can be presented at Card Reader end and application system, and lot of data is stored in in the card application system, in the system as bank; And the data that only can show current transaction need more transaction data as the user, then need in addition to printing or download with the application of card application system.Therefore, the user can not obtain timely, enough relationship trading information usually.
Summary of the invention
Deficiency based on existing application of IC cards system, the invention provides a kind of system and method for realizing that double-interface smart card real-time transaction data information shows, with solve existing application of IC cards system to the transaction data information of intelligent card subscriber in process of exchange to the transparent inadequately problem of user, and further solve information security issue.
