IC card (IntegratedCircuitCard, integrated circuit card), also known as a smart card (Smartcard), smart card (Intelligentcard), micro circuit card (Microcircuitcard) or microchip card, etc.It is a microelectronic chip embedded ISO7816 standard card base, make card form.The communication between IC card read and write with can be contact, also can contact.According to the communication interface of IC card into contact IC card, contactless IC and dual interface card (contact and non-contact communication interface at the same time).IC card information due to its inherent safety, easy to carry, comparative advantages of perfect standardization, the identity authentication, bank, telecommunication, public transportation, yard management, and other fields are being more and more applications, such as the second generation id card, the bank‘s electronic wallet, telecom, mobile phone SIM card, public transit bus card, canvas, parking card for parking charges, etc., all play an important role in People‘s Daily life.According to industry analysts pointed out that: IC card is the card after another kind of information carrier.IC card is refers to the integrated circuit card, generally with the bus card is a kind of IC card, general common IC card USES radio frequency technology and support IC card reader to communicate.There is a difference between IC card and magnetic card, IC card is through the information stored in the IC card, the card is through the magnetic record information in the card.The cost of the IC card is higher than magnetic card, but better secrecy.Contactless IC card is also called radio frequency card, had been solve successfully the source (card without power supply) and contactless this difficult problem, is a breakthrough in the field of electronics.Mainly used for public transport, telecommunications, Banks, yard management, and other fields.Main features include safety certification, electronic purse, data storage, etc.The commonly used access control card, the second generation id card belongs to the application of safety certification, and bank CARDS, canvas is using electronic purse and other functions.By the end of 2013, the cumulative issue bank CARDS 4.214 billion pieces, at present, the per capita has card 3.11.Driven by the gold card project, smart IC card hairpin quantity more than 10 billion copies in China, IC card application in e-government, e-commerce and involve the people life and social activities in the practice of continuously made new achievements, made an important contribution to promote the whole society informatization., is known to be released industry investment decision-making net "smart IC card industry in China in 2014-2018 forecast and investment strategy research report shows that the future trend is as follows:1, the public key infrastructureThe facilities for the use of data encryption technology provides a management framework, a set of two pairs of keys (that is, the public key and private key) and a digital certificate is an important part of public key infrastructure.Private keys and digital certificates are kept by the user, as proof of identity, and public key is open to the public meet and use.Smart card security features, applicable to store private keys and digital certificates.Data from card smuggled to the reader, have been encrypted.Card in a dedicated processor is responsible for the encryption and decryption process, to reduce the risk of leaking Kane private key.2, biological identification technologyIn order to strengthen the ability of smart card authentication, the researchers have introduced biological identification technology to replace the traditional personal password authentication method.Due to the personal password is a string of Numbers, not truly representative of personal identity, but biological identification technology (such as to identify the fingerprint and the pupil) can be used to make up for the deficiency.In recent years, Britain and Japan have some Banks, has begun on the ATM pupil identification method is used to identify the user.In the short term, the biological identification method can be combined with smart card operating system, let users can be used on personal password and biological identification method to confirm identity.
