第二卡槽 14,设置为插入第二信息卡,其中,所述第二信息卡中存储有安全单元; NFC 芯片 16, 设置为通过所述第一卡槽与所述第一信息卡或者通过所述第二卡槽与所述第 二信息卡连接。 在上述装置中,设置了至少两个卡槽,这样就可以实现对多个信息卡的支持。 NFC 芯片可以通过多种方式实现选择与第一信息卡连接还是选择与第二信息卡连接, 在本 实施例中提供了几种优选的实现方式, 这几种优选的实施方式如下: 优选实施方式一: 在该优选方式中采用了开关的方式, 图 2是根据本发明实施例的近场通信装置的 优选结构框图, 如图 2所示, 该优选装置还包括: 开关 22, 开关 22与第一卡槽 12、 第二卡槽 14和 NFC芯片 16连接, 通过开关 22的选择, NFC芯片 16可以通过第一 卡槽 12与第一信息卡建立第一连接, 也可以通过第二卡槽 14与第二信息卡建立的第 二连接。 在该优选实施方式, 只需要使用一个硬件的开关就可以实现连接的切换, 实现比 较简单。作为另一种实现方式,图 2中所示出的开关也可以表示一种软件功能,即 NFC 芯片 16与第一卡槽 12和第二卡槽 14是物理连接的, 但是, 软件来进行控制, 控制选 择这两个物理连接中的之一来进行通信。 优选地, 可以通过主控芯片来控制该开关。此时, 开关 22设置为接收主控芯片的 控制信号并在第一连接和第二连接之间进行切换, 其中, 主控芯片可以通过设置通用 输入输出 (General Purpose Input Output, 简称为 GPIO) 口来控制开关 22。 优选实施方式二: 在本优选实施例中, 不使用开关, 提供了一种至少具有两个接口的 NFC芯片, 图 3是根据本发明实施例的近场通信装置的优选结构框图二, 如图 3所示, 该 NFC芯片 16'至少包括: 与第一卡槽 12连接的第一接口和与第二卡槽 16连接的第二接口; NFC 芯片 16'设置为接收控制信号, 该控制信号用于指示 NFC芯片 16'通过第一接口和第 一卡槽 12与第一信息卡连接或者通过第二接口和第二卡槽 14与第二信息卡建立连接。 在该优选实施方式中, 不再需要额外的开关, 而使用至少具有两个接口的 NFC芯 片, 可以理解为将开关的功能内置于 NFC芯片中, 从而可以使该 NFC芯片支持至少 两个信息卡的连接。 优选实施方式三: 优选实施方式二中使用了一种特别的 NFC芯片, 这需要 NFC芯片制造厂商的支 持, 或者需要定制该特定的 NFC芯片。考虑到这一点, 在本优选实施例中提供了另一 种实施方式, 该优选方式中使用了与信息卡数量等同的 NFC芯片, 图 4是根据本发明 实施例的近场通信装置的优选结构框图三, 该图只象征性的示出了两个卡槽, 如图 4 所示, NFC芯片其实是多个 NFC芯片, 其中包括: 至少一个通过第一卡槽 12与第 一信息卡连接的第一 NFC芯片 162, 以及至少一个通过第二卡槽 14与第二信息卡连 接的第二 NFC芯片 164, 其中, 第一 NFC芯片 162和第二 NFC芯片 164设置为接收 控制信号, 该控制信号用于指示第一 NFC芯片 162与第一信息卡建立连接, 或第二 NFC芯片 164与第二信息卡建立连接。 该实现方式虽然需要使用多个 NFC芯片, 但是在实现上比较简单。 优选地, 第一信息卡可以为用户识别模块 SIM卡。 第二信息卡也可以使 SIM卡, 或者也可以是集成电路 IC卡 (例如, 金融 IC卡)。 作为一个比较优的实现, 该 IC卡 支持 NFC功能的管脚配置可以与 SIM卡支持 NFC功能的管脚配置相同, 和 /或, 该 IC卡的形状规格可以与 SIM卡相同。在这种情况下,两种卡槽的形状以及物理连接就 可以相同, 制造比较简便。 在本实施例中, 还提供了一种近场通信方法, 图 5是根据本发明实施例的近场通 信方法的流程图, 如图 5所示, 该流程包括如下步骤: 步骤 S502, 接收控制信号;

该 NFC芯片设置为接收控制信号, 并根据该控制信号通过该第一接口和该第一 卡槽与该第一信息卡建立连接, 或者通过该第二接口和该第二卡槽与该第二信息卡建 立连接。 又例如, 在 NFC 芯片包括至少一个通过该第一卡槽与该第一信息卡连接的第一 NFC芯片, 以及至少一个通过该第二卡槽与该第二信息卡连接的第二 NFC芯片的情 况下, 可以根据该控制信号控制该第一 NFC芯片与该第一信息卡建立该第一连接, 和 /或控制该第二 NFC芯片与该第二信息卡建立该第二连接。 与装置相同, 优选地, 在上述方法中, 第一信息卡可以为用户识别模块 SIM卡。 第二信息卡也可以使 SIM卡, 或者也可以是集成电路 IC卡 (例如, 金融 IC卡)。 作 为一个比较优的实现, 该 IC卡支持 NFC功能的管脚配置可以与 SIM卡支持 NFC功 能的管脚配置相同, 和 /或, 该 IC卡的形状规格可以与 SIM卡相同。 在这种情况下, 两种卡槽的形状以及物理连接就可以相同, 制造比较简便。 下面以移动终端 (例如, 手机) 为例进行说明, 在该优选实施例中使用了开关的 方式来实现。 本实施例提供了一种具有 NFC功能的手机并支持 SIM卡和金融 IC卡的实现方案, 本实施例能满足运营商的 NFC手机支付业务, 也能满足银联的 NFC手机支付业务, 方便用户自主选择两大 NFC手机支付业务。 在本实施例中提供了一种 SIM卡,该 SIM卡内置安全单元 SE,NFC芯片连接 SIM 卡的单线协议( Single Wire Protocol,简称为 SWP)管脚, NFC芯片和 SIM卡通过 SWP 协议进行通讯。 其中手机与 SIM卡之间通过 IS07816协议进行通讯。 在本实施例中还提供了一种新型金融 IC卡, 该 IC卡被设计成 SIM卡样式, 包括 IC卡芯片和内置于 IC卡芯片中的安全单元 SE,NFC芯片连接金融 IC卡的 SWP管脚, NFC芯片和金融 IC卡通过 SWP协议进行通讯,其中手机与 SIM卡之间通过 IS07816 协议进行通讯。 本实施例中还提供一种 SWP切换开关, 设置为将 SIM卡或者金融 IC卡连接到 NFC芯片。 其中, SWP切换开关通过手机 GPIO口进行控制。 当用户使用 SIM卡进 行刷卡业务时, 手机主控芯片通过设置 GPIO口来控制 SWP切换开关, 使 NFC芯片 与 SIM卡之间导通。 当用户使用金融 IC卡进行刷卡业务时, 手机主控芯片通过设置 GPIO口来控制 SWP切换开关, 使 NFC芯片与金融 IC卡之间导通。 本实施例中还提供一种手机, 该手机主板集成 NFC芯片, 主板上安置两个 SIM 卡卡槽, 主卡槽插入 SIM卡, 副卡槽插入金融 IC卡, NFC天线贴在电池背面或者手 机后盖内侧。 其中, 手机主控芯片与 NFC芯片通过 I2C或者其他高速总线进行通讯。 本实施例提供的 SIM卡内置安全单元 SE, 支持卡模拟, 可将该 SIM卡模拟成公 交卡、 门禁卡、 电子钱包、 银行卡等。 同时, 该 SIM卡具有传统的电信功能, 可进行 打电话发短信和数据业务等。 本实施例提供的金融 IC卡内置安全单元 SE, 也可以支 持卡模拟, 可将该金融 IC卡模拟成公交卡、 门禁卡、 电子钱包、 银行卡等。 同时, 该 IC卡不具备电信功能, 不可以打电话发短信和数据业务等。 图 6是根据本发明实施例的支持 SIM卡和金融 IC卡双 SE方案的结构框图,如图 6所示, 结构图包括手机主控芯片 60, NFC芯片 16, 支持 SE的 SIM卡 12, 支持 SE 的金融 IC卡 14, SWP线的切换开关 22', NFC天线 62, 以及控制 GPIO口的设置模 块 64。 手机主控芯片 60通过 I2C总线与 NFC芯片 16相连, 或者使用其他高速总线。 手机主控芯片 60通过 IS07816接口与 SIM卡 12进行通讯,通过 IS07816接口与 金融 IC卡 14进行通讯,通过设置模块 64控制 GPIO口对 SWP切换开关 22'进行控制。
