也即是说，在刷卡的过程中，第二电子设备使用第一电子设备的第一NFC虚拟卡完成操作，第二电子设备可以不用开通相应的虚拟卡，从而节约了重复开通虚拟卡所消耗的资源，解决了现有技术在多个电子设备上使用智能卡时，需要在各个电子设备开通智能卡，从而造成资源浪费的问题，具有较高的实用性和易用性。

近场无线通信(Near Field Communication，NFC)技术是在非接触式射频识别技术的基础上，结合无线互连技术研发而成，电子设备可以应用NFC技术模拟各类智能卡，例如公交卡、门禁卡、银行卡、智能门锁、NFC车钥匙等智能卡。
但是，如果用户想让电子设备模拟智能卡，需要在电子设备上开通相应的智能卡。例如，用户如果想让手机实现公交卡的功能，需要在手机上先开通电子公交卡。
通常在电子设备上开通卡片需要支付一定的开卡费用，例如，当前许多公交卡都需要20至30元的开卡费用。因此，当用户拥有多个电子设备时，如果想让多个电子设备都模拟智能卡，则需要在多个电子设备都开通卡片，这在一定程度上存在资源浪费。
并且，当前大多数智能卡都是以不记名的方式开通的，如果在各个电子设备上均开通智能卡，一旦用户更换电子设备或者电子设备遗失，则该电子设备的智能卡内的余额也无法找回，容易造成不必要的损失。
有鉴于此，本申请实施例提供了一种智能卡分享方法、装置、电子设备及计算机可读存储介质，可以使多个电子设备共享智能卡，从而解决现有技术在多个电子设备上使用智能卡时，需要在各个电子设备开通智能卡，从而造成资源浪费的问题。
首先，以图1所示的智能卡分享系统为例，对本申请中即将涉及的各个电子设备进行举例说明。
如图1所示，在智能卡分享系统中包括第一电子设备101、第二电子设备102以及NFC读卡器103。
其中，第一电子设备101表示已开通智能卡的电子设备，第二电子设备102表示请求分享智能卡的电子设备。
在第一电子设备101中，包括处理器1011、NFC芯片1012以及无线通信模块1013。
在第二电子设备102中，包括处理器1021、NFC芯片1022以及无线通信模块1023。
上述NFC芯片可在电子设备与NFC读卡器103之间实现非接触式通信。NFC芯片可允许电子设备在较低数据速率(例如106kbps)下与NFC读卡器103进行近程通信，并可遵守任何适当的标准，诸如IS0/IEC 7816、IS0/IEC 18092、ECMA-340、IS0/IEC 21481、ECMA-352、IS0 14443以及ISO 15693等标准中的任意一种或多种。除此以外，NFC芯片也可允许电子设备在较高数据速率(例如560Mbps)下与NFC读卡器103进行近程通信，并可遵守任何适当标准，诸如Transfer Jet TM协议。
上述无线通信模块的具体类型可以根据实际情况进行选择。例如，上述无线通信模块可以包括蓝牙(bluetooth，BT)模块、无线保真(wireless fidelity，Wi-Fi)模块、蜂窝网络模块等模块中的一种或多种。
第一电子设备101可以通过无线通信模块1013与第二电子设备102的无线通信模块1023建立无线连接通道104。无线通信模块1013和无线通信模块1023中应当包括至少一种相同类型的无线通信模块，否则无线通信模块1013和无线通信模块1023无法建立无线连接通道104。
例如，假设无线通信模块1013中包括蓝牙模块以及蜂窝网络模块，则无线通信模块1023中应当包括蓝牙模块和蜂窝网络模块中的至少一种无线通信模块，比如，无线通信模块1023可以包括蓝牙模块以及Wi-Fi模块。此时，无线通信模块1013和无线通信模块1023均包括蓝牙模块，无线通信模块1013和无线通信模块1023可以建立蓝牙连接通道。假设无线通信模块1023只包括Wi-Fi模块，则无线通信模块1013中的蓝牙模块和蜂窝网络模块均无法与无线通信模块1023中的Wi-Fi模块建立无线连接通道104。
当第二电子设备102与NFC读卡器103处于适当的近程距离(例如0厘米到4厘米的范围)时，第二电子设备102的NFC芯片1022可与NFC读卡器103建立NFC连接通道105。
可以理解的是，上述第一电子设备101以及第二电子设备102的具体类型可以根据实际情况进行设置。例如，上述电子设备可以为手机、平板电脑、可穿戴设备、车载设备、增强现实(augmented  reality，AR)/虚拟现实(virtual reality，VR)设备、笔记本电脑、超级移动个人计算机(ultra-mobile personal computer，UMPC)、上网本、个人数字助理(personal digital assistant，PDA)等电子设备中的任意一种，本申请实施例对电子设备的具体类型不作任何限制。
作为示例而非限定，当上述电子设备为可穿戴设备时，该可穿戴设备还可以是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，如智能手表或智能眼镜等，以及只专注于某一类应用功能，需要和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能首饰等。
以下，将根据图1所示的智能卡分享系统并结合具体的应用场景，对本申请实施例提供的智能卡分享方法进行详细说明。
首先，第一电子设备101可以响应于用户的第一操作，将智能卡(即前述NFC虚拟卡)的通信参数分享给第二电子设备102。
如图2所示，第一电子设备101的NFC芯片1012中，可能管理着一个已开通的智能卡，或者，也可能管理着多个已开通的智能卡，例如图2中的智能卡1、智能卡2至智能卡n，n为大于2的正整数。第一电子设备101可以与第二电子设备102建立无线连接通道104，并基于用户的选择操作确定需要分享的智能卡，或者，第一电子设备101也可以是默认分享当前激活的智能卡。
然后，第一电子设备101的处理器1011从NFC芯片1012中获取需要分享的智能卡(即前述第一NFC虚拟卡)的通信参数，通过无线通信模块1013将智能卡的通信参数传递至第二电子设备102的无线通信模块1023。
第二电子设备102的处理器1021通过无线通信模块1023获取到第一电子设备101分享的智能卡的通信参数后，将该智能卡的通信参数存储至NFC芯片1022进行管理。
其中，上述无线连接通道104的类型可以根据实际情况进行选择。例如，上述无线连接通道104可以为蓝牙连接通道、Wi-Fi连接通道、蜂窝网络连接通道等通道中的任意一种或多种。
上述智能卡的通信参数可以根据具体选用的NFC通信协议以及智能卡的类型进行确定。例如，当第一电子设备101和第二电子设备102选用ISO14443协议时，如果需要分享的智能卡为公交卡，则第一电子设备101需要分享给第二电子设备102的智能卡的通信参数可以包括NFC卡片的唯一识别码(unique identifier，UID)、NFC-A类请求指令的应答(answer to request-type A，ATQA)、选择确认(select acknowledge，SAK)、选择应答(answer to select，ATS)等参数中的一种或多种。
以下将结合具体的应用场景对上述智能卡参数配置步骤进行说明。
应用场景一：
在本应用场景中，假设第一电子设备101为手机，第二电子设备102为智能手表。上述无线通信模块1013中包括第一蓝牙模块，无线通信模块1023中包括第二蓝牙模块，手机通过第一蓝牙模块与智能手表的第二蓝牙模块建立蓝牙连接通道。
在手机和智能手表初次建立蓝牙连接通道时，手机可以响应于用户对手机的实体按键的按压操作或对手机的显示屏的触摸操作等操作，从休眠状态进入工作状态，并进入手机的主页页面。
如图3所示，手机的主页页面中可以包括一个或多个图标，例如“天气”、“相机”、“浏 览器”、“视频”、“钱包”、“计算器”、“相册”、“设置”等图标。当用户操作这些图标时，可以进入相应的应用程序或系统功能。
如图4和图5所示，手机可以响应于用户的向下滑动操作，唤出状态栏。在手机的状态栏中，设置有一个或多个控件图标，例如“WLAN”、“NFC”、“移动数据”、“振动”、“自动旋转”、“飞行模式”、“免打扰”、“蓝牙”等控件图标。
然后，手机可以响应于用户对蓝牙功能的控件图标的长按点击操作，进入蓝牙功能的设置页面。
或者，手机也可以响应于用户对手机的主页页面中的“设置”图标的点击操作，进入系统设置页面。
如图6所示，在系统设置页面中，包括多种系统功能的设置选项，例如“软件更新”、“无线与网络”、“设备连接”、“桌面和壁纸”、“手势识别”、“显示”、“声音”、“通知中心”、“安全与隐私”、“用户和账户”等设置选项。
手机可以响应于用户对“设备连接”选项的点击操作，进入“设备连接”的设置页面。“设备连接”的设置页面中可以包括多种设备连接的设置选项，例如“蓝牙”、“NFC”等。
之后，手机可以响应于用户对“蓝牙”选项的点击操作，进入蓝牙功能的设置页面。
如图7所示，在蓝牙功能的设置页面中，可以包括蓝牙功能的开关按键以及设备名称设置选项。手机可以响应于用户对蓝牙功能的开关按键的点击操作，开启手机的蓝牙功能。
在开启了手机的蓝牙功能之后，手机可以显示历史中已配对的设备(例如Flypods 3)，以及可用设备(例如智能手表、设备3、设备4以及设备5)。可用设备表示电子设备目前搜索到的，可以建立蓝牙连接电子设备。在蓝牙功能的设置页面的底部，还设置有“扫描”和“帮助”选项，当用户想重新扫描周围开启了蓝牙功能的电子设备时，手机可以响应于用户对“扫描”按键的点击操作，重新扫描周围开启了蓝牙功能的电子设备。
之后，手机可以响应于用户对可用设备中智能手表的选项的点击操作，与智能手表建立蓝牙连接通道。
此外，如果手机和智能手表并非首次建立蓝牙连接，则在手机和智能手表的蓝牙功能开启后，手机和智能手表可以自动配对建立蓝牙连接通道。
如图8所示，在手机与智能手表建立蓝牙连接通道后，手机可以响应于用户的操作，返回主页页面，然后，手机响应于用户对“钱包”图标的点击操作，进入钱包应用程序。
如图9所示，在钱包应用程序的主页面中，可以包括“刷卡”、“付款码”、“扫一扫”、“零钱”等功能，以及钱包应用程序提供的一些服务，比如“借钱”、“信用卡”、“交通”、“智卡”、“代币”、“充值”、“商城”、“发票”等。
在钱包应用程序的主页面的底部，设置有至少一个页面切换选项，比如“首页”、“生活”、“卡包”、“我的”。其中，“首页”为钱包应用程序的主页面，手机可以响应于用户对“卡包”选项的点击操作，切换至智能卡的页面。
如图10所示，在“卡包”页面中，可以根据类别收纳相应的智能卡。例如，智能卡的类别可以包括“银行卡”、“交通卡”、“证件”。
假设用户需要将岭南通交通卡的通信参数传递给智能手表时，则手机可以响应于用户对“交通卡”的选项的点击操作，进入交通卡收纳界面。
如图11所示，手机中可能已开通了多张交通卡，手机可以响应于用户对岭南通交通卡的点击 操作，进入岭南通交通卡界面。
如图12所示，手机进入岭南通交通卡界面后，手机可以响应于用户对右上角的按键的点击操作，弹出“优惠券”、“设置默认卡”以及“分享”选项，然后手机可以响应于用户对“分享”按键的点击操作，在页面底部弹出分享选择栏。
如图13所示，手机可以响应于用户对分享选择栏中“蓝牙”选项的点击操作，弹出分享提示框。当手机检测到用户对分享提示框中的“是”按键的点击操作时，手机将岭南通交通卡的通信参数传递至智能手表，或者，当手机检测到用户对分享提示框中的“否”按键的点击操作时，手机取消将岭南通交通卡的通信参数传递至智能手表的操作。
需要说明的是，虽然在上述应用场景中第一电子设备101和第二电子设备102通过蓝牙连接通道传递智能卡的通信参数，但是，在实际的应用过程中，除了蓝牙连接通道以外，还可以通过其他类型的无线连接通道104传递智能卡的通信参数，例如，第一电子设备101还可以通过Wi-Fi连接通道、蜂窝网络连接通道等方式，将第一电子设备101上的智能卡的通信参数传递至第二电子设备102。本申请对第一电子设备101传递智能卡的通信参数给第二电子设备102的方式不做任何限制。
在第一电子设备101将智能卡的通信参数传递至第二电子设备102之后，第二电子设备102可以执行相应智能卡的刷卡操作。
当用户使用第二电子设备102执行刷卡操作时，第二电子设备102可以响应于用户的操作，开启无线通信功能，使得第二电子设备102的无线通信模块1023与第一电子设备101的无线通信模块1013建立无线连接通道104。并且，第二电子设备102还可以响应于用户的操作，开启NFC功能。
在实际的操作过程中，第二电子设备102可以先开启无线通信功能，再开启电子设备NFC功能；或者，第二电子设备102也可以先开启电子设备NFC功能，再开启电子设备无线通信功能。
第二电子设备102在开启了NFC功能后，电子设备如果第二电子设备102与NFC读卡器103的距离保持在合适的近程距离(例如0厘米到4厘米)，则第二电子设备102的NFC芯片1022可以与NFC读卡器103建立NFC连接通道105。
之后，NFC读卡器103可以通过NFC连接通道105发送第一交易请求给第二电子设备102的NFC芯片1022。
NFC芯片1022接收到第一交易请求后，将第一信息请求传递至处理器1021，处理器1021通过无线通信模块1023将第一信息请求发送至第一电子设备101的无线通信模块1013。
其中，第一交易请求中包括上述被分享的智能卡的通信参数中的部分参数或全部参数。第一交易请求和第一信息请求可以为相同的请求，或者，第一交易请求和第一信息请求也可以为不同的请求。
例如，第二电子设备102接收到第一交易请求之后，直接将第一交易请求转发至第一电子设备101，此时，第一交易请求和第一信息请求为相同的请求。或者，第二电子设备102接收到第一交易请求之后，通过处理器1021对第一交易请求进行处理，比如格式转换、通信参数提取等处理，从而得到第一信息请求，然后再将第一信息请求发送至第一电子设备101，此时，第一交易请求和第一信息请求为不同的请求。
第一电子设备101的处理器1011通过无线通信模块1013接收到第一信息请求后，将第一信息请求传入NFC芯片1012中进行处理。
如图14所示，NFC芯片1012中可以包括NFC控制器芯片以及安全芯片。其中，NFC控制器芯片用于控制NFC芯片与其他支持NFC功能的电子设备建立NFC连接通道105。安全芯片是可信任平台模块，是一个可独立进行密钥生成、加解密的装置，封装有安全芯片的NFC芯片可以实现各类身份识别操作以及支付操作，使NFC芯片可以模拟各类需要进行身份验证操作的智能卡以及涉及资金交易的智能卡，例如银行卡、公交卡等。
处理器1011获取到第一信息请求后，可以将第一信息请求传入NFC芯片1012的安全芯片中进行处理。
安全芯片对第一信息请求处理完毕后，反馈智能卡响应信息(即前述第一响应信息)至处理器1011。
处理器1011获取到智能卡响应信息后，通过无线通信模块1013将智能卡响应信息发送至第二电子设备102。
第二电子设备102的处理器1021通过无线通信模块1023接收到智能卡响应信息后，将智能卡响应信息传入NFC芯片1022的NFC控制器芯片，由NFC芯片1022的NFC控制器芯片通过NFC连接通道105将智能卡响应信息发送至NFC读卡设备，完成刷卡操作。
以下结合具体的应用场景对上述刷卡过程进行说明。
应用场景二：
在本场景中，假设用户携带有第一电子设备101和第二电子设备102，第一电子设备101为手机，第二电子设备102为智能手表。手机的无线通信模块1013包含有第一蓝牙模块，智能手表的无线通信模块1023包含有第二蓝牙模块，手机通过第一蓝牙模块与智能手表的第二蓝牙模块建立蓝牙连接通道。
以用户打算乘坐公共汽车为例，用户在上车时，双手拎着东西，不便掏出手机扫码支付，用户通过智能手表刷卡支付。
如图15所示，NFC读卡器103在工作时，会产生NFC场强。在智能手表靠近NFC读卡器103的过程中，智能手表可以在合适的近程距离内检测到NFC场强。
出于节省电量的考虑，手机等电子设备如果在预设时长内没有检测到用户的操作，会进入休眠状态，因此，当智能手表在检测到NFC场强大于预设场强阈值后，智能手表的处理器1021可以通过第二蓝牙模块发送进场通知给手机，上述进场通知用于唤醒手机，提醒手机配合后续的刷卡操作。
当手机的处理器1011通过第一蓝牙模块接收到进场通知时，如果手机处于休眠状态，则处理器1011控制手机退出休眠状态，进入工作状态。
之后，智能手表的NFC芯片1022和NFC读卡器103可以基于ISO14443-3协议规定的内容进行初始化操作，建立NFC连接通道105。
建立了NFC连接通道105之后，NFC读卡器103通过NFC连接通道105发送选择应答请求(request for answer to select，RATS)指令给智能手表的NFC芯片1022。
智能手表的NFC芯片1022接收到RATS指令后，根据RATS指令检查NFC芯片1022中是否设置有相应的公交卡的通信参数。如果智能手表的NFC芯片1022中设置有相应的公交卡的通信参数，则智能手表通过NFC连接通道105回复ATS指令给NFC读卡器103，并且智能手表的处理器1021还可以通过第二蓝牙模块发送相应的卡片激活通知给手机的第一蓝牙模块。
手机的处理器1011通过第一蓝牙模块接收到卡片激活通知后，准备执行刷卡操作。
如图16所示，NFC读卡器103接收到ATS指令后，通过NFC连接通道105发送智能卡交互(application protocol data unit，APDU)命令(即第一交易请求)给智能手表的NFC芯片1022。
智能手表的NFC芯片1022接收到APDU命令后，通过I2C接口将APDU命令传递至处理器1021，处理器1022通过第二蓝牙模块将APDU命令传递至手机的第一蓝牙模块。
手机的处理器1011通过第一蓝牙模块接收到APDU命令后，通过SPI接口将APDU命令传入NFC芯片1012的安全芯片中。
如图17所示，NFC芯片1012的安全芯片对APDU命令进行处理，得到APDU响应(即智能卡响应信息)，并通过SPI接口将APDU响应传递至手机的处理器1011。
手机的处理器1011通过第一蓝牙模块将APDU响应传递至智能手表的第二蓝牙模块。
智能手表的处理器1021通过第二蓝牙模块接收到APDU响应后，通过I2C接口将APDU响应传递至NFC芯片1022。NFC芯片1022通过NFC连接通道105将APDU响应发送至NFC读卡器103。
至此，NFC读卡器103和智能手表完成了一次APDU指令的交互。
可以理解的是，NFC读卡器103和智能手表在刷卡过程中，可能需要进行一次或多次APDU指令的交互。当NFC读卡器103和智能手表需要进行多次APDU指令的交互时，NFC读卡器103、智能手表以及手机可以参照上述图15、图16和图17所示的APDU指令的交互过程进行多次APDU指令的交互。
上述蓝牙模块的具体类型可以根据实际情况进行选择。例如，上述蓝牙模块可以是标准的蓝牙模块，或者，上述蓝牙模块也可以是低功耗蓝牙(Bluetooth Low Energy，BLE)模块。此外，在实际的应用中，还可以选用其他通信范围合适的通信模块以代替上述蓝牙模块。例如，可以采用Wi-Fi模块代替上述蓝牙模块。
应用场景三：
在应用场景二中，无线通信模块1013和无线通信模块1023为蓝牙模块、Wi-Fi模块等通信距离较短的无线通信模块，因此，应用场景二所展示的刷卡过程适用于用户同时携带有第一电子设备101和第二电子设备102的近程刷卡场景。
但是，在另一些场景中，用户可能不会同时携带第一电子设备101和第二电子设备102。例如，在家庭中，可能父亲在自己的手机上开通了电子公交卡后，手机通过上述智能卡参数配置步骤，将公交卡的通信参数传递至儿童的智能手表上。当儿童使用智能手表进行公交卡刷卡操作时，父亲不一定在身边，即父亲的手机和儿童的智能手表的空间距离较远，智能手表无法通过蓝牙模块、Wi-Fi模块等通信距离较短的无线通信模块与手机建立无线连接通道104，导致智能手表无法实现上述刷卡过程。
因此，在应用场景三中，如图18所示，第一电子设备101的无线通信模块1013中可以包括第一蜂窝网络模块，第二电子设备102的无线通信模块1023中可以包括第二蜂窝网络模块。此时，第一电子设备101和第二电子设备102可以通过第一蜂窝网络模块以及第二蜂窝网络模块建立蜂窝网络连接通道，并通过蜂窝网络连接通道实现上述刷卡过程。
在本应用场景中，假设第一电子设备101为父亲的手机，第二电子设备102为儿童的智能手表，智能手表支持蜂窝网络。
儿童在单独乘坐公共汽车时，使用智能手表执行刷卡支付操作。
NFC读卡器103在工作时，会产生NFC场强。智能手表在靠近NFC读卡器103的过程中， 智能手表可以在合适的近程距离内检测到NFC场强。如果智能手表检测到NFC场强且NFC场强大于预设场强阈值，则智能手表的处理器1021通过第二蜂窝网络模块发送进场通知给手机，上述进场通知用于唤醒手机，提醒手机配合后续的刷卡操作。
当手机的处理器1011通过第一蜂窝网络模块接收到进场通知时，如果手机处于休眠状态，则处理器1011退出休眠状态，进入工作状态。
之后，智能手表的NFC芯片1022和NFC读卡器103可以基于ISO14443-3协议规定的内容进行初始化操作，建立NFC连接通道105。
建立了NFC连接通道105之后，NFC读卡器103通过NFC连接通道105发送选择应答请求(request for answer to select，RATS)指令给智能手表。
智能手表的NFC芯片1022接收到RATS指令后，根据RATS指令检查NFC芯片1022中是否设置有相应的公交卡的通信参数。如果智能手表的NFC芯片1022中设置有相应的公交卡的通信参数，则智能手表通过NFC连接通道105回复ATS指令给NFC读卡器103，并且智能手表的处理器1021还可以通过第二蜂窝网络模块发送相应的卡片激活通知给手机的第一蜂窝网络模块。
手机的处理器1011通过第一蜂窝网络模块接收到卡片激活通知后，准备执行刷卡操作。
NFC读卡器103接收到ATS指令后，通过NFC连接通道105发送智能卡交互(application protocol data unit，APDU)命令(即第一交易请求)给智能手表的NFC芯片1022。
智能手表的NFC芯片1022接收到APDU命令后，将APDU命令传递至处理器1021，处理器1022通过第二蜂窝网络模块将APDU命令传递至手机的第一蜂窝网络模块。
手机的处理器1011通过第一蜂窝网络模块接收到APDU命令后，将APDU命令传入NFC芯片1012的安全芯片中。
NFC芯片1012的安全芯片对APDU命令进行处理，得到APDU响应(即智能卡响应信息)，并将APDU响应传递至手机的处理器1011。手机的处理器1011通过第一蜂窝网络模块将APDU响应传递至智能手表的第二蜂窝网络模块。
智能手表的处理器1021通过第二蜂窝网络模块接收到APDU响应后，将APDU响应传递至NFC芯片1022。NFC芯片1022通过NFC连接通道105将APDU响应发送至NFC读卡器103。
至此，NFC读卡器103和智能手表完成了一次APDU指令的交互。
可以理解的是，NFC读卡器103和智能手表在刷卡过程中，可能需要进行一次或多次APDU指令的交互。当NFC读卡器103和智能手表需要进行多次APDU指令的交互时，NFC读卡器103、智能手表以及手机可以参照上述APDU指令的交互过程进行多次APDU指令的交互。
需要说明的是，上述蜂窝网络模块的具体类型可以根据实际情况进行选择。例如，上述蜂窝网络模块可以为2G蜂窝网络模块、3G蜂窝网络模块、4G蜂窝网络模块、5G蜂窝网络模块或未来可能出现的更多制式的蜂窝网络模块。本申请对蜂窝网络模块的具体类型不作任何限制。
通过上述应用场景二以及上述应用场景三的示例可知，第二电子设备102不在本地对第一交易请求进行处理，而是通过无线连接通道104将第一信息请求发送至第一电子设备101进行处理，然后接收第一电子设备101返回的智能卡响应信息。
因此，在刷卡的过程中，第二电子设备102可能需要在较长的时间后，才能接收到第一电子设备101返回的智能卡响应信息并将智能卡响应信息反馈至NFC读卡器103。
而在NFC读卡器103中，可能设置有预设时间阈值的等待时长。NFC读卡器103可以设置一个定时器，通过第一定时器记录NFC读卡器103等待的时间，如果NFC读卡器103等待的时间 超过了预设时间阈值且未接收到智能卡响应信息，则NFC读卡器103会断开与第二电子设备102的NFC连接通道105。
所以，在一些可能的实现方式中，第二电子设备102的处理器1021可以在接收到第一交易请求，并发送第一信息请求至第一电子设备101后，可以启动一个第二定时器。第二定时器的定时时长小于上述预设时间阈值。
如果处理器1021在第二定时器超时之前接收到第一电子设备101发送的智能卡响应信息，则停止第二定时器，将智能卡响应信息发送至NFC读卡器103以完成刷卡操作。
如果处理器1021在第二定时器超时之前未接收到第一电子设备101发送的智能卡响应信息，则通过NFC连接通道105发送等待请求至NFC读卡器103。
NFC读卡器103接收到等待请求后，延长可等待时长或刷新第一定时器，重新计算NFC读卡器的等待时长。然后，NFC读卡器103通过NFC连接通道105返回等待响应至第二电子设备102。
第二电子设备102的处理器1021通过NFC芯片1022接收到等待响应后，刷新处理器1021设置的第二定时器，重新开始计时。
如果第二定时器再次超时，则第二电子设备102可以重复上述步骤，重复发送等待请求至NFC读卡器103，请求NFC读卡器继续等待。
以下将结合具体的应用场景对上述超时等待功能进行说明。
应用场景四：
假设NFC读卡器103上设置有第一定时器，第一定时器的定时时长为2s，如果第一定时器超时，则NFC读卡器103断开与第二电子设备102的NFC连接通道105。
第二电子设备102上设置有第二定时器，第二定时器的定时时长为1.5s。
如图19所示，在NFC读卡器103发送APDU命令至第二电子设备102后，NFC读卡器103启动第一定时器，第一定时器开始计时。
第二电子设备102接收到APDU命令后，开启第二定时器并将APDU命令发送至第一电子设备101。
在1.5s后，第二定时器超时且未接收到APDU响应，第二电子设备102发送等待请求(WTX REQ)给NFC读卡器103。
NFC读卡器103接收到WTX REQ后，重置第一定时器，使第一定时器重新开始计时，并回复等待响应(WTX RES)给第二电子设备102。
第二电子设备102接收到WTX RES后，重置第二定时器，使第二定时器重新开始计时。
在1.5s后，第二定时器超时且仍未接收到APDU响应，第二电子设备102再次发送WTX REQ给NFC读卡器103。
NFC读卡器103接收到WTX REQ后，再次重置第一定时器，使第一定时器重新开始计时，并回复WTX RES给第二电子设备102。
第二电子设备102接收到WTX RES后，重置第二定时器，使第二定时器重新开始计时。
在1s后，第一电子设备101发送APDU响应给第二电子设备102。
第二电子设备102接收到APDU响应后，关闭第二定时器，将APDU响应发送至NFC读卡器103。
NFC读卡器103接收到APDU响应后，关闭第一定时器，完成本次APDU指令的交互。
在上述描述的应用场景二、应用场景三以及应用场景四中，第一电子设备101和第二电子设 备102均建立了无线连接通道104，且第一电子设备101分享了智能卡的通信参数给第二电子设备102。
但是，在另一些应用场景中，第一电子设备101可能无法与第二电子设备102建立无线连接通道104。此时，第二电子设备102无法使用第一电子设备101上开通的智能卡。
因此，在一些可能的实现方式中，用户可以在第二电子设备102上也开通智能卡。
当用户使用第二电子设备102执行刷卡操作时，第二电子设备102的处理器1021可以先检查无线通信模块1023是否与无线通信模块1013建立了无线连接通道104。
如果无线通信模块1023未与无线通信模块1013建立无线连接通道104，则处理器1021可以通知NFC芯片1022调用本地开通的智能卡执行刷卡操作。
如果无线通信模块1023与无线通信模块1013建立了无线连接通道104，则处理器1021可以通知NFC芯片1022调用第一电子设备101开通的智能卡执行刷卡操作。
进一步地，即使第一电子设备101的无线通信模块1013与第二电子设备102的无线通信模块1023建立了无线连接通道104，但是，第一电子设备101也可能因为未开通智能卡等原因，未将智能卡的通信参数分享给第二电子设备102，此时，第二电子设备102也无法使用第一电子设备101的智能卡。
因此，在一些可能的实现方式中，当用户使用第二电子设备102执行刷卡操作时，第二电子设备102的处理器1021可以先检查无线通信模块1023是否与无线通信模块1013建立了无线连接通道104，以及检测第一电子设备101是否已分享智能卡的通信参数。
比如，在第二电子设备102的处理器1021中，可以设置通道状态参数和智能卡状态参数。
通道状态参数用于记录无线连接通道104的状态。例如，处理器1021可以用1和0表示无线通信模块1023是否与无线通信模块1013建立无线连接通道104；当通道状态参数为0时，表示未建立无线连接通道104；当通道状态参数为1时，表示已建立无线连接通道104。
智能卡状态参数用于记录智能卡的通信参数的状态。例如，处理器1021可以用1和0表示第一电子设备101是否分享智能卡的通信参数给第二电子设备102；当智能卡状态参数为0时，表示第一电子设备101未分享智能卡的通信参数给第二电子设备102；当通道状态参数为1时，表示第一电子设备101已分享智能卡的通信参数给第二电子设备102。
根据上述通道状态参数以及智能卡状态参数可以确定第二电子设备102的终端状态，处理器1021根据第二电子设备102的终端状态，指示NFC芯片1022执行相应的刷卡操作。
如图20所示，第二电子设备102的终端状态可以主要划分为关机状态、单机状态、联机状态以及共享状态。
在关机状态下，第二电子设备102保留NFC功能，但是第二电子设备102无法与第一电子设备101建立无线连接通道104。当处于关机状态的第二电子设备102执行刷卡操作时，NFC芯片1022可以检测本地是否开通了相应的智能卡。如果第二电子设备102上开通了相应的智能卡，则第二电子设备102可以使用本地开通的智能卡执行刷卡操作；如果第二电子设备102未开通相应的智能卡，则第二电子设备102无法完成相应的刷卡操作，刷卡失败。
在单机状态下，第二电子设备102已开机，但是未与第一电子设备101建立无线连接通道104。当处于单机状态的第二电子设备102执行刷卡操作时，处理器1021可以指示NFC芯片1022检测本地是否开通了相应的智能卡。如果第二电子设备102上开通了相应的智能卡，则第二电子设备102可以使用本地开通的智能卡执行刷卡操作；如果第二电子设备102未开通相应的智能卡，则 第二电子设备102无法完成相应的刷卡操作，刷卡失败。
在联机状态下，第二电子设备102已开机，且第二电子设备102与第一电子设备101建立了无线连接通道104，但是，可能因为第一电子设备101未开通智能卡，或第一电子设备101未将第一电子设备101的智能卡的通信参数分享至第二电子设备102等因素，导致第二电子设备102上不存在第一电子设备101的智能卡的通信参数。当处于联机状态的第二电子设备102执行刷卡操作时，处理器1021可以指示NFC芯片1022检测本地是否开通了相应的智能卡。如果第二电子设备102上开通了相应的智能卡，则第二电子设备102可以使用本地开通的智能卡执行刷卡操作；如果第二电子设备102未开通相应的智能卡，则第二电子设备102无法完成相应的刷卡操作，刷卡失败。
在分享状态下，第二电子设备102已开机，第二电子设备102与第一电子设备101建立了无线连接通道104，并且第一电子设备101分享了智能卡的通信参数给第二电子设备102。当处于分享状态的第二电子设备102执行刷卡操作时，处理器1021可以指示NFC芯片1022优选选择第一电子设备101分享的智能卡执行上述刷卡操作；如果第一电子设备101分享的智能卡匹配，则根据以上描述的内容完成刷卡操作；如果第一电子设备101分享的智能卡不匹配，则NFC芯片1022选择本地开通的相应的智能卡执行刷卡操作；如果第二电子设备102未开通相应的智能卡，则第二电子设备102无法完成相应的刷卡操作，刷卡失败。
此外，第二电子设备102并非固定处于某一终端状态，第二电子设备102的终端状态可以根据实际情况进行切换。
如图20所示，当第二电子设备102处于关机状态时，第二电子设备102可以响应于用户的开机操作启动设备，此时，第二电子设备102的终端状态可以在开机后从关机状态切换至单机状态。
当第二电子设备102与第一电子设备101建立了无线连接通道104时，则第二电子设备恩102的终端状态可以从单机状态切换至联机状态。
在联机状态下，如果第一电子设备101将智能卡的通信参数同步至第二电子设备102，则第二电子设备102的终端状态由联机状态切换至共享状态。
但是，如果第一电子设备101将智能卡的通信参数同步至第二电子设备102时，通信参数同步失败，或者，第二电子设备102删除了第一电子设备101同步的智能卡的通信参数，则第二电子设备102的终端状态由共享状态切换至联机状态。
当第二电子设备102的终端状态处于联机状态或共享状态时，一旦无线连接通道104断开连接，则第二电子设备102的终端状态切换至单机状态。
当第二电子设备102的终端状态处于单机状态、联机状态或共享状态时，第二电子设备102可以响应于用户的关机操作关闭设备，此时，第二电子设备102的终端状态切换至关机状态。
以下将结合具体的应用场景对第二电子设备102在不同的终端状态下的刷卡流程进行介绍。
在以下的各个应用场景中，可以假设第一电子设备101为手机，第二电子设备102为智能手表，第一电子设备101的无线通信模块1013包括第一蓝牙模块，第二电子设备102的无线通信模块1023包括第二蓝牙模块。
在第二电子设备102的处理器1021中，设置有Ch2_Status(即通道状态参数)和Terminal_Status(即智能卡状态参数)。当Ch2_Status＝0时，表示手机和智能手表未建立蓝牙连接通道；当Ch2_Status＝1时，表示手机和智能手表已建立蓝牙连接通道；当Terminal_Status＝0时，表示手机未分享智能卡的通信参数给智能手表；当Terminal_Status＝1时，表示手机已分享智能卡的通信参 数给智能手表。
应用场景五：
智能手表处于关机状态，此时，智能手表上大部分功能不可用，仅保留少数功能，比如NFC功能。
用户在公共汽车上使用智能手表执行刷卡操作。当智能手表检测到NFC场强且NFC场强大于预设场强阈值时，智能手表的NFC芯片1022与NFC读卡器103建立NFC连接通道105。
之后，NFC读卡器103通过NFC连接通道105发送RATS指令给智能手表的NFC芯片1022。
智能手表的NFC芯片1022根据RATS指令查询本地是否开通了公交卡。如果NFC芯片1022查询到本地已开通公交卡，则NFC芯片1022回复该公交卡对应的ATS指令给NFC读卡器103。
NFC读卡器103接收到ATS指令后，进入APDU指令的交互过程。NFC读卡器103通过NFC连接通道105发送APDU命令给NFC芯片1022。
NFC芯片1022在NFC芯片1022的安全芯片中对APDU命令进行处理，得到APDU响应，并通过NFC连接通道105将APDU响应返回至NFC读卡器103，完成一次APDU指令的交互。
当刷卡过程仅需进行一次APDU指令的交互时，则NFC芯片1022和NFC读卡器103完成了公交卡刷卡操作。
当刷卡过程需要进行多次APDU指令的交互时，则NFC芯片1022和NFC读卡器103重复上述APDU指令的交互过程进行多次APDU指令的交互，从而完成公交卡刷卡操作。
此外，如果NFC芯片1022查询到本地未开通公交卡，则NFC芯片1022刷卡失败。
应用场景六：
智能手表已开机，用户在公共汽车上使用智能手表执行刷卡操作。当智能手表检测到NFC场强且NFC场强大于预设场强阈值时，智能手表的NFC芯片与NFC读卡器103建立NFC连接通道105。
之后，NFC读卡器103通过NFC连接通道105发送RATS指令给智能手表的NFC芯片1022。
智能手表的NFC芯片1022发送刷卡通知给处理器1021。处理器1021根据刷卡通知查询Ch2_Status和Terminal_Status。
智能手表的处理器1021查询到Ch2_Status＝0，Terminal_Status＝0或1，则表示智能手表为单机状态。此时，处理器1021通知NFC芯片1022使用本地智能卡执行刷卡操作。
智能手表的NFC芯片1022接收到处理器1021的通知后，根据RATS指令查询本地是否开通了公交卡。如果NFC芯片1022查询到本地已开通公交卡，则NFC芯片1022回复该公交卡对应的ATS指令给NFC读卡器103。
NFC读卡器103接收到ATS指令后，进入APDU指令的交互过程。NFC读卡器103通过NFC连接通道105发送APDU命令给NFC芯片1022。
NFC芯片1022在NFC芯片1022的安全芯片中对APDU命令进行处理，得到APDU响应，并通过NFC连接通道105将APDU响应返回至NFC读卡器103，完成一次APDU指令的交互。
当刷卡过程仅需进行一次APDU指令的交互时，则NFC芯片1022和NFC读卡器103完成了公交卡刷卡操作。
当刷卡过程需要进行多次APDU指令的交互时，则NFC芯片1022和NFC读卡器103重复上述APDU指令的交互过程进行多次APDU指令的交互，从而完成公交卡刷卡操作。
此外，如果NFC芯片1022查询到本地未开通公交卡，则NFC芯片1022刷卡失败。
应用场景七：
智能手表已开机，用户在公共汽车上使用智能手表执行刷卡操作。当智能手表检测到NFC场强且NFC场强大于预设场强阈值时，智能手表的NFC芯片与NFC读卡器103建立NFC连接通道105。
之后，NFC读卡器103通过NFC连接通道105发送RATS指令给智能手表的NFC芯片1022。
智能手表的NFC芯片1022发送刷卡通知给处理器1021。处理器1021根据刷卡通知查询Ch2_Status和Terminal_Status。
智能手表的处理器1021查询到Ch2_Status＝1，Terminal_Status＝0，则表示智能手表为联机状态。此时，处理器1021通知NFC芯片1022使用本地智能卡执行刷卡操作。
智能手表的NFC芯片1022接收到处理器1021的通知后，根据RATS指令查询本地是否开通了公交卡。如果NFC芯片1022查询到本地已开通公交卡，则NFC芯片1022回复该公交卡对应的ATS指令给NFC读卡器103。
NFC读卡器103接收到ATS指令后，进入APDU指令的交互过程。NFC读卡器103通过NFC连接通道105发送APDU命令给NFC芯片1022。

智能手表的NFC芯片1022接收到处理器1021的通知后，根据RATS指令查询第一电子设备101分享的智能卡的通信参数中是否包含公交卡的通信参数。
如果第一电子设备101分享的智能卡的通信参数中包含公交卡的通信参数，则NFC芯片1022回复该公交卡对应的ATS指令给NFC读卡器103，并通过应用场景二所述的APDU指令的交互方式完成公交卡刷卡操作。
如果第一电子设备101分享的智能卡的通信参数中不包含公交卡的通信参数，则智能手表的NFC芯片根据RATS指令查询本地是否开通了公交卡。如果NFC芯片1022查询到本地已开通公交卡，则NFC芯片1022回复该公交卡对应的ATS指令给NFC读卡器103。

此外，如果NFC芯片1022查询到本地未开通公交卡，则NFC芯片1022刷卡失败。
应用场景九：
在本应用场景中，将会对开通智能卡、分享智能卡以及刷卡支付的流程进行描述。
如图8所示，手机可以响应于用户对“钱包”图标的点击操作，进入钱包应用程序。
如图9所示，在钱包应用程序的主页面的底部，设置有至少一个页面切换选项，比如“首页”、“生活”、“卡包”、“我的”。
手机可以响应于用户对“卡包”选项的点击操作，切换至智能卡的页面。
如图10所示，在“卡包”页面中，可以根据类别收纳相应的智能卡。例如，智能卡的类别可以包括“银行卡”、“交通卡”、“证件”。
手机可以响应于用户对“交通卡”的选项的点击操作，进入交通卡收纳界面。
如图21所示，手机中可能已开通了多张交通卡。
如图22和图23所示，手机可以响应于用户的左滑操作或右滑操作切换不同的交通卡的显示界面。比如，手机可以响应于用户的左滑操作，从岭南通交通卡界面切换至深圳通交通卡界面。
如图24和图25所示，假设用户想要开通新的交通卡，则手机可以响应于用户对交通卡界面右上角的“+”图标的点击操作，进入可开通的交通卡列表界面。
如图26所示，假设用户想要开通京津翼互联互通卡，则手机可以响应于用户对京津翼互联互通卡的选项的点击操作，进入京津翼互联互通卡的开通界面。
如图27所示，然后手机可以响应于用户对“下一步”选项的点击操作以及支付操作，进入智能卡加载界面。
智能卡加载完成后，京津翼互联互通卡添加成功。
假设用户希望分享岭南通交通卡至智能手表。手机可以响应于用户的操作，开启蓝牙功能，与智能手表建立蓝牙连接通道。
如果岭南通交通卡为默认卡，则表示手机当前激活的智能卡为岭南通交通卡。如图28所示，此时，手机可以响应于用户对钱包应用程序的主页面的“分享”选项的点击操作，在页面底部弹出分享选择栏。
如图29所示，手机可以响应于用户对分享选择栏中“蓝牙”选项的点击操作，弹出分享提示框。当手机检测到用户对分享提示框中的“是”按键的点击操作时，手机将当前被激活的智能卡(即岭南通交通卡)的通信参数传递至智能手表，或者，当手机检测到用户对分享提示框中的“否”按键的点击操作时，手机取消将当前被激活的智能卡(即岭南通交通卡)的通信参数传递至智能手表的操作。
或者，如图30和图31所示，手机也可以响应于用户对岭南通交通卡的显示界面的“分享” 选项的点击操作，弹出分享提示框。当手机检测到用户对分享提示框中的“是”按键的点击操作时，手机将当前被激活的智能卡(即岭南通交通卡)的通信参数传递至智能手表，或者，当手机检测到用户对分享提示框中的“否”按键的点击操作时，手机取消将当前被激活的智能卡(即岭南通交通卡)的通信参数传递至智能手表的操作。
如图32所示，手机响应于与用户对分享提示框中的“是”按键的点击操作，将岭南通交通卡的通信参数传递至智能手表。
上述通信参数包括NFC卡片的唯一识别码(unique identifier，UID)、NFC-A类请求指令的应答(answer to request-type A，ATQA)、选择确认(select acknowledge，SAK)、选择应答(answer to select，ATS)等参数中的一种或多种。
如图33所示，在手机分享了岭南通交通卡的通信参数至智能手表之后，手机可以创建该岭南通交通卡的副卡，副卡为分享至其他电子设备的智能卡。
副卡的显示形态可以根据实际需求进行设置。例如，可以将副卡的显示卡片调节为半透明状态，以此区分手机上开通的智能卡和分享至其他电子设备的副卡。
刷卡支付过程以用户乘坐公共汽车的场景为例。
假设用户上车后，手机放在口袋中，手机和智能手表建立了蓝牙连接通道。此时，用户使用智能手表执行刷卡操作。
在智能手表靠近NFC读卡器103的过程中，智能手表可以在合适的近程距离内检测到NFC场强。
当智能手表在检测到NFC场强大于预设场强阈值后，智能手表的处理器1021可以通过第二蓝牙模块发送进场通知给手机，上述进场通知用于唤醒手机，提醒手机配合后续的刷卡操作。
当手机的处理器1011通过第一蓝牙模块接收到进场通知时，如果手机处于休眠状态，则处理器1011控制手机退出休眠状态，进入工作状态。
之后，智能手表的NFC芯片1022和NFC读卡器103可以基于ISO14443-3协议规定的内容进行初始化操作，建立NFC连接通道105。
建立了NFC连接通道105之后，NFC读卡器103通过NFC连接通道105发送选择应答请求(request for answer to select，RATS)指令给智能手表的NFC芯片1022。
智能手表的NFC芯片1022接收到RATS指令后，智能手表的NFC芯片1022发送刷卡通知给处理器1021。处理器1021根据刷卡通知查询Ch2_Status和Terminal_Status。
智能手表的处理器1021查询到Ch2_Status＝1，Terminal_Status＝1，则表示智能手表为分享状态。此时，处理器1021通知NFC芯片1022使用优先使用第一电子设备101分享的智能卡执行刷卡操作。
智能手表的NFC芯片1022接收到处理器1021的通知后，根据RATS指令检查NFC芯片1022中是否设置有相应的公交卡的通信参数。如果智能手表的NFC芯片1022中设置有相应的公交卡的通信参数，则智能手表通过NFC连接通道105回复ATS指令给NFC读卡器103，并且智能手表的处理器1021还可以通过第二蓝牙模块发送相应的卡片激活通知给手机的第一蓝牙模块。
手机的处理器1011通过第一蓝牙模块接收到卡片激活通知后，准备执行刷卡操作。
如图16所示，NFC读卡器103接收到ATS指令后，通过NFC连接通道105发送智能卡交互(application protocol data unit，APDU)命令给智能手表的NFC芯片1022，并启动第一定时器，第一定时器的定时时长为2s，将第一定时器的启动时间假定为第0s。
智能手表的NFC芯片1022接收到APDU命令后，通过I2C接口将APDU命令传递至处理器1021，处理器1022通过第二蓝牙模块将APDU命令传递至手机的第一蓝牙模块，并且，第二电子设备102启动第二定时器，第二定时器的定时时长为1.5s。
手机的处理器1011通过第一蓝牙模块接收到APDU命令后，通过SPI接口将APDU命令传入NFC芯片1012的安全芯片中。
如图17所示，NFC芯片1012的安全芯片对APDU命令进行处理，得到APDU响应(即智能卡响应信息)，并通过SPI接口将APDU响应传递至手机的处理器1011。
手机的处理器1011在第2s时通过第一蓝牙模块将APDU响应传递至智能手表的第二蓝牙模块。
其中，由于2s大于1.5s，因此，在第1.5s时，第二定时器超时且未接收到APDU响应，第二电子设备102发送等待请求(WTX REQ)给NFC读卡器103。
NFC读卡器103接收到WTX REQ后，重置第一定时器，使第一定时器重新开始计时，并回复等待响应(WTX RES)给第二电子设备102。
第二电子设备102接收到WTX RES后，重置第二定时器，使第二定时器重新开始计时。
在第2s时，智能手表的处理器1021通过第二蓝牙模块接收到APDU响应后，通过I2C接口将APDU响应传递至NFC芯片1022。NFC芯片1022通过NFC连接通道105将APDU响应发送至NFC读卡器103，并关闭第二定时器。
NFC读卡器103接收到APDU响应时，对APDU响应进行处理，并关闭第一定时器。
至此，NFC读卡器103和智能手表完成了一次APDU指令的交互。
可以理解的是，NFC读卡器103和智能手表在刷卡过程中，可能需要进行一次或多次APDU指令的交互。当NFC读卡器103和智能手表需要进行多次APDU指令的交互时，NFC读卡器103、智能手表以及手机可以参照上述图15、图16和图17所示的APDU指令的交互过程进行多次APDU指令的交互。
在刷卡完成后，手机101的钱包应用程序接收到远端服务器发送的交易成功通知。此时，手机可以通过振动或发出提示音的方式提示收到新消息，并亮屏显示该交易成功通知；或者，手机也可以接收该交易成功通知，但不执行消息提示操作。
此外，手机的处理器1011还可以通过第一蓝牙模块将交易成功通知传递至智能手表的第二蓝牙模块。智能手表的处理器1021通过第二蓝牙模块接收到交易成功通知后，执行相应的消息提示操作。
消息提示操作的形式可以根据实际情况进行设置。例如，如图34所示，智能手表102可以通过振动的方式提示用户收到新消息，并亮屏显示“交易成功”。
综上，在本申请实施例提供的智能卡分享方法中，当第二电子设备102执行刷卡操作时，可以将NFC读卡器103发送的第一信息请求发送至第一电子设备101进行处理，并在第一电子设备101对第一信息请求处理完毕后，将第一电子设备101反馈的智能卡响应信息转发至NFC读卡器103，完成刷卡操作。
当第二电子设备102使用第一电子设备101分享的智能卡时，无需在第二电子设备102上开通相应的智能卡，因此，第二电子设备102不用支付相应的开卡费用。
并且，由于第二电子设备102只是借用电子设备101分享的智能卡，该智能卡存在于电子设备101上，因此，即使第二电子设备102遗失，该智能卡也不会遗失。
此外，当用户更换了新的电子设备时，第一电子设备101也可以通过上述智能卡参数配置步骤，将第一电子设备101的智能卡分享至新的电子设备上，不会因为更换了新的电子设备，导致旧的电子设备上的智能卡闲置。
同时，由于第二电子设备102在使用第一电子设备101分享的智能卡时，NFC读卡器103发送的第一信息请求是由第一电子设备101的NFC芯片1012处理的。因此，第二电子设备102的NFC芯片1022中可以不设置安全芯片。由于NFC芯片中，安全芯片的成本占据整个NFC芯片的总成本的70％左右，因此，当NFC芯片1022不设置安全芯片时，虽然第二电子设备102无法独立支持NFC的智能卡功能，但是可以极大地降低NFC芯片的成本，减少资源消耗。
当上述无线通信模块1013和无线通信模块1023均包括蜂窝网络模块时，即使用户并未同时携带第一电子设备101和第二电子设备102，第二电子设备102也可以通过蜂窝网络连接通道远程使用第一电子设备101分享的智能卡。
另外，在一些应用场景中，第二电子设备102可能无法与第一电子设备101建立无线连接通道，无法使用第一电子设备101分享的智能卡。因此，用户也可以在第二电子设备102上开通部分智能卡以应对此类特殊应用场景。此时，第二电子设备102可以根据无线连接通道104的状态以及智能卡的通信参数的状态，确定自身的终端状态，并根据终端状态针对性地选择第一电子设备101分享的智能卡执行刷卡操作，或者，选择本地开通的智能卡执行刷卡操作。
应理解，上述实施例中各步骤的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本申请实施例的实施过程构成任何限定。
