Financial IC card is also known as chip bank card, is the bank card using chip as medium.Chip card capacity is big, Ke Yicun
The information such as key, digital certificate, fingerprint are stored up, working principle is similar to microcomputer, can handle multiple functions simultaneously, be
The convenience of holder's offer one card for multiple uses.
Financial IC card is issued by business bank (credit office) or payment mechanism, using integrated circuit technique, it then follows state
Family's financial industry standard, has consumer credit, the transfer and settlement of accounts, cash-access all or part financial function, can have other
The financial instrument of commerce services and social management function.There are two types of chip card standards in the market, and one is in the world using more
EMV standard, one is the PBOC2.0 standards of People's Bank of China.
Financial IC card is the tool that modern information technologies are merged with financial service height, using chip technology and financial industry
Standard can have both bank card, ensure the multi-functionals such as card, management card, have safety, convenience, standard and scalability
The advantages that.
Financial IC card has apparent advantage:
