图5示出的是与本发明实施例提供的掌纹识别装置的部分结构的框图。参考图5，掌纹识别装置包括：存储器410、输入单元420、显示单元430、手掌信息采集装置440、音频电路450、无线保真(wireless fidelity，WiFi)模块460、处理器470、以及电源480等部件。本领域技术人员可以理解，图5中示出的手机结构并不构成对手机的限定，可以包括比图示更多或更少的部件，或者组合某些部件，或者不同的部件布置。
下面结合图5对手机的各个构成部件进行具体的介绍：
存储器410可用于存储软件程序以及模块，处理器470通过运行存储在存储器410的软件程序以及模块，从而执行掌纹识别装置的各种功能应用以及数据处理。存储器410可主要包括存储程序区和存储数据区，其中， 存储程序区可存储操作系统、至少一个功能所需的应用程序(比如掌纹采集失败报警功能、掌纹采集功能等)等；存储数据区可存储根据手机的使用所创建的数据(比如掌纹数据等)等。此外，存储器410可以包括高速随机存取存储器，还可以包括非易失性存储器，例如至少一个磁盘存储器件、闪存器件、或其他易失性固态存储器件。

尽管未示出，掌纹识别装置还可以包括蓝牙模块等，在此不再赘述。
前述实施例中，各步骤方法流程可以基于该设备的结构实现。值得注意的是，上述手掌信息采集设备实施例中，所包括的各个单元只是按照功能逻辑进行划分的，但并不局限于上述的划分，只要能够实现相应的功能即可；另外，各功能单元的具体名称也只是为了便于相互区分，并不用于 限制本发明的保护范围。
另外，本领域普通技术人员可以理解实现上述各方法实施例中的全部或部分步骤是可以通过程序来指令相关的硬件完成，相应的程序可以存储于一种计算机可读存储介质中，上述提到的存储介质可以是只读存储器，磁盘或光盘等。
以上仅为本发明较佳的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明实施例揭露的技术范围内，可轻易想到的变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应该以权利要求的保护范围为准。
