Description

The finger-print cipher keyboard that suitable bank savings is used

The utility model relates to the finger-print cipher keyboard that a kind of suitable bank savings is used.

Along with electronics; computing machine; the continuous development of network; the Electronic Finance informationization has reached its maturity universal; but in the process of electronic information; identification is a bottleneck problem; at present main solution is to adopt password; because what access to your password is local too many; easily password is forgotten; so the client is easy to some passwords (as the birthday; home telephone number etc.) as universal code; no matter which bankbook all uses this password, password just becomes and " plain code " like this, needs only others and knows your birthday or home telephone; just known your password, so produced " password crisis ".

The purpose of this utility model is will provide a kind of can solve " password crisis ", and the client is freed from the password worry, and is easy to operation, good confidentiality, the finger-print cipher keyboard that safe suitable bank savings is used.

The purpose of this utility model realizes with the following methods.Should be fit to finger-print cipher keyboard that bank savings uses comprise key board, as the cpu controller of central processing controller, there are fingerprint instrument and cpu controller to join, the IC-card interface that is connected with cpu controller in addition, the IC-card interface can insert the IC-card of storing information such as fingerprint, cpu controller also connects serial line interface, serial line interface can link to each other with various interfaces such as terminal, computing machine or converters, is used for transmission command or data; For showing various duties or operating result, cpu controller also connects liquid crystal display circuit; Cpu controller also connects voice warning circuit, integrated circuit of clock, memory body integrated circuit.

Below in conjunction with the embodiment accompanying drawing the utility model is described in further detail.
