由于硬件技术的约束，虽然钱包应用程序中模拟出了多张模拟卡，但是一次只能激活一张模拟卡。用户可在钱包应用程序中设置默认卡，例如，如图4所示，用户设置门禁卡“我的家”为默认卡。激活卡为门禁卡“我的家”，NFC读卡器101为深圳公交闸机的读卡器，此时需要将默认卡门禁卡切换为目标卡公交卡，以完成刷卡操作。
一种相关技术中，示例性地，如图5a至图5d所示，门禁卡为默认卡，NFC读卡器101为公交闸机的读卡器。则用户通过电子设备100在公交闸机处刷卡时，电子设备100上会弹出默认卡门禁卡，如图5a所示，电子设备100上弹出门禁卡“我的家”；此时用户需要手动将门禁卡切换为公交卡，如图5b所示，用户在电子设备100上点击公交卡“深圳通”；如图5c所示，将门禁卡“我的家”切换为公交卡“深圳通”，电子设备100上弹出公交卡“深圳通”，并在公交卡的下方显示公交卡的余额为￥27.18以及“充值”按钮；而后，如图5d所示，电子设备100通过公交卡“深圳通”在公交闸机处完成刷卡交易，交易时间为2020/9/14 17:08，交易金额为￥2.00，公交卡余额为￥25.18。此种方案中，无论NFC读卡器101为哪种类型的读卡器，电子设备100在检测到NFC读卡器101的NFC射频场时，总是弹出默认卡，当默认卡为门禁卡，NFC读卡器101为公交闸机的读卡器，此时需要用户手动换卡，并在换卡之后再次进行刷卡操作，从而降低了刷卡效率。
另一种相关技术中，用户通过电子设备100在NFC读卡器101上进行刷卡操作时，电子设备100检测到NFC读卡器101的NFC射频场之后，接收到NFC读卡器101发送的NFC控制器接口(NFC Controller Interface，简称NCI)流。NCI是NFC控制器102与操作系统通信的标准协议。NCI的类型可包括命令类型、通知类型或数据类型。通知类型的NCI是NFC控制器102与NFC读卡器101通信后将通信状态通知到操作系统侧的NCI。电子设备100根据获取到的AID选择AID对应的模拟卡，而后将默认卡切换为AID对应的模拟卡。但是，当默认卡为门禁卡，NFC读卡器101为公交闸机的读卡器时，由于NFC读卡器101不会向电子设备发送AID，导致电子设备100无法基于AID识别出NFC读卡器101的读卡类型，电子设备100无法实现基于AID自动将门禁卡切换为公交卡，需要用户手动换卡(手动换卡的过程可参见图5a至图5d所示)，并在换卡之后再次进行刷卡操作，从而降低了刷卡效率。
另一种相关技术中，示例性地，如图6a所示，提供了一种基于位置切换模拟卡的方案，以门禁刷卡点为中心建立地理围栏，地理围栏覆盖预定区域(图6a中圆圈所示的区域)，门禁刷卡点设置有门禁卡读卡器。用户进入地理围栏的预定区域之前，即：用户的电子设备100的位置位于地理围栏的预定区域之外时，电子设备100的激活卡为默认卡公交卡；用户进入地理围栏的预定区域，即：用户的电子设备100的位置位于地理围栏的预定区域内时，电子设备100去激活默认卡公交卡并激活门禁卡，以实现基于位置将公交卡切换为门禁卡；用户离开地理围栏的预定区域，即：用户的电子设备100的位置位于地理围栏的预定区域之外时，电子设备100去激活门禁卡并激活默认卡公交卡，以实现还原默认卡公交卡。示例性地，如图6b所示，一般来说，地理围栏的围栏半径较大，则地理围栏的预定区域会覆盖到公交刷卡点(或地铁刷卡点)，公交刷卡点设置有NFC读卡器101，在用户移动至公交刷卡点的过程中，一进入地理围栏的预定区域，电子设备100就会将默认卡公交卡切换为门禁卡；而后用户移动至公交刷卡点进行刷卡操作时，由于激活卡为门禁卡，且NFC读卡器101为公交闸机的读卡器时，由于NFC读卡器101不会向电子设备发送AID，导致电子设备100无法基于AID识别出NFC读卡器101的读卡类型，电子设备100无法实现基于AID自动将门禁卡切换为公交卡，需要用户手动换卡(手动换卡的过程可参见图5a至图5d所示)，并在换卡之后再次进行刷卡操作，从而降低了刷卡效率。

示例性地，AID为A000000632010105，该AID对应的模拟卡为深圳通互联互通卡。由于京津冀互联互通卡与深圳通互联互通卡为同一类型的模拟卡，因此京津冀互联互通卡对应的AID也为A000000632010105。
示例性地，小区门禁读卡器支持的协议为ISO14443-3协议，由于ISO14443-3协议为不选择AID的协议，因此，小区门禁读卡器不具备对应的AID。
NFC读卡器的读卡类型可包括电子设备能够读取的模拟卡的类型，如上表2所示，一个NFC读卡器可对应于一个或者多个AID，换言之，一个NFC读卡器能够读取一种或多种类型的模拟卡。例如，深圳公交闸机的读卡器对应于两个AID，则深圳公交闸机的读卡 器能够读取深圳通和深圳通互联互通卡两种类型的模拟卡；上海公交闸机的读卡器对应于一个AID，则上海公交闸机的读卡器能够读取上海通一种类型的模拟卡。
如上表1和表2所示，例如：不选择AID的协议包括ISO14443-3协议，选择AID的协议包括ISO14443-4协议。若SAK＝0x08时，SAK对应的卡支持协议包括ISO14443-3协议；若SAK0x20或者SAK＝0x28时，SAK对应的卡支持协议包括ISO14443-3协议和ISO14443-4协议。
示例性地，NFC读卡器从电子设备读取到SAK＝0x08，SAK＝0x08指明第一模拟卡只支持ISO14443-3协议，不支持ISO14443-4协议，NFC读卡器执行ISO14443-3协议的业务流程，不会执行ISO14443-4协议的业务流程，此时NFC读卡器执行不选择AID的业务流程，因此可将ISO14443-3协议称为不选择标识信息(AID)的协议。
示例性地，NFC读卡器从电子设备读取到SAK＝0x20或者SAK＝0x28，SAK＝0x20或者SAK＝0x28指明第一模拟卡支持ISO14443-3协议和ISO14443-4协议，NFC读卡器执行ISO14443-3协议的业务流程和ISO14443-4协议的业务流程，由于NFC读卡器支持执行ISO14443-4协议的业务流程，此时NFC读卡器可执行选择AID的业务流程，因此可将ISO14443-4协议称为选择标识信息(AID)的协议。
NFC读卡器可以基于SAK和NFC读卡器支持的协议确定出第一协议，并与电子设备执行第一协议的业务流程。当NFC读卡器从电子设备读取到SAK之后，可根据SAK确定出SAK对应的卡支持协议，再根据SAK对应的卡支持协议和NFC读卡器支持的协议确定出第一协议，并与电子设备执行第一协议的业务流程。例如：若SAK对应的卡支持协议包括不选择AID的协议(例如，ISO14443-3协议)，且NFC读卡器支持的协议包括不选择AID的协议(例如，ISO14443-3协议)和选择AID的协议(例如，ISO14443-4协议)，则NFC读卡器确定出的第一协议包括不选择AID的协议(例如，ISO14443-3协议)；又例如：若SAK对应的卡支持协议包括不选择AID的协议(例如，ISO14443-3协议)，且NFC读卡器支持的协议包括不选择AID的协议(例如，ISO14443-3协议)，则NFC读卡器确定出的第一协议包括不选择AID的协议(例如，ISO14443-3协议)；又例如：SAK对应的卡支持协议包括不选择AID的协议(例如，ISO14443-3协议)和选择AID的协议(例如，ISO14443-4协议)，且NFC读卡器支持的协议包括不选择AID的协议(例如，ISO14443-3协议)，则NFC读卡器确定出的第一协议包括不选择AID的协议(例如，ISO14443-3协议)；又例如：SAK对应的卡支持协议包括不选择AID的协议(例如，ISO14443-3协议)和选择AID的协议(例如，ISO14443-4协议)，NFC读卡器支持的协议包括不选择AID的协议(例如，ISO14443-3协议)和选择AID的协议(例如，ISO14443-4协议)，则NFC读卡器确定出的第一协议包括不选择AID的协议(例如，ISO14443-3协议)和选择AID的协议(例如，ISO14443-4协议)。电子设备在与NFC读卡器执行第一协议的业务流程的过程中，会产生第一NCI流。而后，电子设备若判断出第一NCI流不包括AID，则判断出满足协议信息调整条件，需要对SAK进行修改，例如，将SAK＝0x08修改为SAK＝0x20，或者将SAK＝0x08修改为SAK＝0x28；电子设备若判断出第一NCI流包括AID，则判断出不满足协议信息调整条件，不需要对SAK进行修改，此时SAK对应的卡支持协议包括选择AID的协议，例如，ISO14443-4协议，SAK＝0x20或者SAK＝0x28。
电子设备在进行是否满足协议信息调整条件的判断操作以及修改SAK或不修改SAK 之后，SAK对应的卡支持协议均包括选择AID的协议(例如，ISO14443-4协议)。而后，NFC读卡器还可以基于SAK和NFC读卡器支持的协议确定出第二协议，并与电子设备执行第二协议的业务流程。当NFC读卡器再次从电子设备读取到SAK之后，可根据再次读取的SAK确定出SAK对应的卡支持协议，再根据SAK对应的卡支持协议和NFC读卡器支持的协议确定出第二协议，并与电子设备执行第二协议的业务流程。此时，SAK对应的卡支持协议包括选择AID的协议(例如，ISO14443-4协议)，在此基础上，若NFC读卡器支持的协议包括不选择AID的协议(例如，ISO14443-3协议)，NFC读卡器确定出的第二协议包括不选择AID的协议(例如，ISO14443-3协议)；若NFC读卡器支持的协议包括不选择AID的协议(例如，ISO14443-3协议)和选择AID的协议(例如，ISO14443-4协议)，NFC读卡器确定出第二协议包括不选择AID的协议(例如，ISO14443-3协议)和选择AID的协议(例如，ISO14443-4协议)。电子设备在与NFC读卡器执行第二协议的业务流程的过程中，会产生第二NCI流。若第二协议包括不选择AID的协议(例如，ISO14443-3协议)和选择AID的协议(例如，ISO14443-4协议)，则NFC读卡器在与电子设备执行第二协议的业务流程的过程中，会向电子设备发送AID，因此电子设备生成的第二NCI流中包括AID，而后，电子设备判断出第二NCI流包括AID，则判断出满足换卡条件，需要进行换卡操作。若第二协议包括不选择AID的协议(例如，ISO14443-3协议)，则NFC读卡器在与电子设备执行第二协议的业务流程的过程中，不会向电子设备发送AID，因此电子设备生成的第二NCI流中不包括AID，电子设备若判断出第二NCI流不包括AID，则判断出不满足换卡条件，无需进行换卡操作。
需要说明的是：若NFC读卡器确定出第一协议包括不选择AID的协议(例如，ISO14443-3协议)和选择AID的协议(例如，ISO14443-4协议)，NFC读卡器与电子设备在执行第一协议的业务流程的过程中，NFC读卡器与电子设备先执行不选择AID的协议(例如，ISO14443-3协议)的业务流程，而后再执行选择AID的协议(例如，ISO14443-4协议)的业务流程。
需要说明的是：若NFC读卡器确定出第二协议包括不选择AID的协议(例如，ISO14443-3协议)和选择AID的协议(例如，ISO14443-4协议)，NFC读卡器与电子设备在执行第二协议的业务流程的过程中，先执行不选择AID的协议(例如，ISO14443-3协议)的业务流程，而后再执行选择AID的协议(例如，ISO14443-4协议)的业务流程。
下面结合模拟卡的切换场景，通过一些具体的实施例对模拟卡的切换方法做出示例性说明。
在一些实施例中，激活卡为门禁卡。用户可在电子设备上设置默认卡为门禁卡，以使得激活卡为门禁卡；或者，如图6b所示，以门禁卡读卡器为中心建立地理围栏，地理围栏的预定区域覆盖到公交闸机，用户可在电子设备上设置默认卡为公交卡，基于地理围栏技术将默认卡公交卡切换为门禁卡，具体描述可参见对图6b的描述。
示例性地，如图7所示，用户从小区的家沿路径S1移动至小区外的公交车站，并在公交闸机处进行刷卡操作。用户将电子设备100的背面靠近公交闸机的读卡器，如图8a所示，电子设备100上显示“正在运行智闪卡”的提示，以及显示“请将手机背面靠近刷卡区域”的提示。公交闸机的读卡器从电子设备100读取SAK，由于激活卡为我的家门禁卡，因此读取的SAK＝0x08。公交闸机的读卡器根据读取的SAK(0x08)确定出SAK对 应的卡支持协议为ISO14443-3协议，因此公交闸机的读卡器根据SAK对应的ISO14443-3协议以及自身支持的ISO14443-3协议和ISO14443-4协议，确定出第一协议包括ISO14443-3协议，并执行ISO14443-3协议的业务流程。而后，电子设备100判断出执行ISO14443-3协议的业务流程时产生的NCI流不包括AID，因此无法基于AID将门禁卡切换为AID对应的公交卡。为了实现切换为公交卡的目的，电子设备100将SAK配置为0x20，即将SAK＝0x08修改为SAK＝0x20。此时，公交闸机的读卡器再次从电子设备读取SAK，读取的SAK＝0x20。公交闸机的读卡器根据读取的SAK(0x20)获取到SAK对应的卡支持协议为ISO14443-4协议，而公交闸机的读卡器自身支持的协议为ISO14443-4协议，因此公交闸机的读卡器根据SAK对应的ISO14443-3协议以及自身支持的ISO14443-3协议和ISO14443-4协议，确定出第二协议包括ISO14443-3协议和ISO14443-4协议，并执行ISO14443-3协议和ISO14443-4协议的业务流程。而后，电子设备100判断出执行ISO14443-3协议和ISO14443-4协议的业务流程时产生的NCI流包括AID，确定出进行换卡操作，进而基于AID将我的家门禁卡切换为AID对应的公交卡深圳通，即电子设备100去激活我的家门禁卡，激活“深圳通”，如图8b所示，电子设备100上弹出激活的公交卡“深圳通”，并在公交卡“深圳通”的下方显示公交卡的余额为￥27.18以及“充值”按钮。电子设备100通过公交卡“深圳通”与公交闸机完成刷卡交易，如图8c所示，电子设备100上显示本次交易金额为￥2.00，显示本次交易时间为2020/9/14 17:08，并显示公交卡的余额为￥25.18。
示例性地，如图7所示，用户在从公交车上下车后，沿路径S2先从公交车站移动至小区的门禁卡读卡器所在位置，并在门禁卡读卡器处进行刷卡操作。用户将电子设备的背面靠近门禁卡读卡器，如图9a所示，电子设备100上显示“正在运行智闪卡”的提示，以及显示“请将手机背面靠近刷卡区域”的提示。门禁卡读卡器从电子设备100读取SAK，由于激活卡为我的家门禁卡，因此读取的SAK＝0x08。门禁卡读卡器根据读取的SAK(0x08)确定出SAK对应的卡支持协议为ISO14443-3协议，因此门禁卡读卡器根据SAK对应的ISO14443-3协议和以及自身支持的ISO14443-3协议和ISO14443-4协议，确定出第一协议包括ISO14443-3协议，并执行ISO14443-3协议的业务流程。而后，电子设备100判断出执行ISO14443-3协议的业务流程时产生的NCI流不包括AID，因此电子设备100将SAK配置为0x20，即将SAK＝0x08修改为SAK＝0x20。此时，门禁卡读卡器再次从电子设备读取SAK，读取的SAK＝0x20。门禁卡读卡器根据读取的SAK(0x20)获取到SAK对应的卡支持协议为ISO14443-4协议，而门禁卡读卡器自身支持的协议为ISO14443-3协议，无论SAK的值是多少，SAK对应的卡支持协议是哪种协议，由于门禁卡读卡器自身支持的协议为ISO14443-3协议，因此门禁卡读卡器在根据SAK对应的ISO14443-4协议以及自身支持的ISO14443-3协议和ISO14443-4协议确定第二协议时最终都会确定出第二协议为ISO14443-3协议，并与电子设备执行ISO14443-3协议的业务流程。电子设备100判断出执行ISO14443-3协议的业务流程时产生的NCI流不包括AID，无法执行基于AID的换卡操作，因此不会对门禁卡进行换卡操作。如图9b所示，电子设备100上弹出门禁卡“我的家”。电子设备100通过门禁卡与门禁卡读卡器完成刷卡操作，如图9c所示，电子设备100上显示“刷卡成功”，而后小区的门打开，用户继续沿路径S2移动至家所在位置。

需要说明的是，上述SAK、AID和协议均为本申请实施例的示例性展示，SAK、AID和协议均可以为其它内容，本申请实施例对此不作限定。
本申请实施例提供的模拟卡的切换方法的技术方案中，电子设备通过调整激活卡第一模拟卡的协议信息，使得NFC读卡器能够根据调整后的协议信息和自身支持的协议与电子设备执行指定协议的业务流程，电子设备执行协议的业务流程时获取到AID并基于AID自动将第一模拟卡切换为AID对应的第二模拟卡，实现了自动换卡，从而提高了刷卡效率。
下面通过与相关技术中自动换卡的方法进行对比，并且以电子设备包括手机以及NFC包括公交闸机的读卡器为例，对本申请实施例的技术方案进行详细描述。
如图15a所示，用户通过手机在公交闸机处进行刷卡操作。手机的激活卡为门禁卡，手机靠近公交闸机，公交闸机从手机读取SAK，此时SAK为0x08，SAK对应的卡支持协议为不选择AID的协议ISO14443-3协议。公交闸机与手机执行ISO14443-3协议的业务流程，在执行ISO14443-3协议的业务流程中公交闸机不会向手机返回AID。手机无法基于AID进行换卡，当前激活卡仍为门禁卡，弹出门禁卡。用户在手机上查看到弹出门禁卡，向手机输入换卡操作，例如，换卡操作包括点击深圳通公交卡(如图5b所示)，将门禁卡切换为深圳通公交卡。手机基于深圳通公交卡与公交闸机完成刷卡交易，刷卡成功。
如图15b所示，用户通过手机在公交闸机处进行刷卡操作。手机的激活卡为门禁卡，手机靠近公交闸机，公交闸机从手机读取SAK，此时SAK为0x08，SAK对应的卡支持协议为不选择AID的协议ISO14443-3协议，公交闸机与手机执行ISO14443-3协议的业务流程，在执行ISO14443-3协议的业务流程中公交闸机不会向手机返回AID。手机将SAK修改为0x20，公交闸机从手机读取SAK，此时SAK为0x20，SAK对应的卡支持协议包括不选择AID的协议ISO14443-3协议和选择AID的协议ISO14443-4协议。公交闸机与手机执行ISO14443-3协议的业务流程和ISO14443-4协议的业务流程，在执行ISO14443-4协议的业务流程中公交闸机会向手机返回AID。手机基于AID自动将门禁卡切换为AID对应的深圳通公交卡。手机基于深圳通公交卡与公交闸机完成刷卡交易，刷卡成功。
从上述图15a和图15b所示，相关技术的方案需要手动将门禁卡切换为深圳通公交卡，而本申请实施例的方案可实现自动将门禁卡切换为深圳通公交卡，从而实现了自动换卡，提高了刷卡效率。
相关技术中可基于AID进行模拟卡的切换。若激活卡为默认卡，NFC读卡器为小区门禁读卡器时，需要将默认卡切换为目标卡。
小区门禁读卡器支持的协议包括不选择AID的协议，门禁卡对应的卡支持协议包括不 选择AID的协议，因此门禁卡没有对应的AID。当用户通过电子设备在小区门禁读卡器处进行刷卡操作时，需要盲等一段预设时间，在预设时间内判断是否获取到小区门禁读卡器发送的AID，若未获取到AID，通过排除法确定出目标卡为门禁卡，即小区门禁读卡器所要刷的模拟卡为门禁卡，而后将默认卡切换为门禁卡，以实现智选到门禁卡。电子设备刷卡时需要进入NFC读卡器的场强，且需要盲等一段预设时间，造成模拟卡的切换速度慢，导致刷卡速度慢，从而降低了刷卡效率。
用户通过电子设备在小区门禁读卡器处进行刷卡操作时，小区门禁读卡器先读取到电子设备上预设置的默认卡后，电子设备上的钱包应用即便立即完成自动换卡，以将默认卡切换到目标卡，小区门禁读卡器也不会重新进行读卡，从而造成刷卡失败。此时需要用户将电子设备从小区门禁读卡器处拿开，然后重新靠近小区门禁读卡器才能刷卡成功。此种异常是小区门禁读卡器的行为引起的，但也是刷卡时，在小区门禁读卡器的场强内才能进行模拟卡的切换操作引起的副作用。这样造成模拟卡的切换速度慢，导致刷卡速度慢，从而降低了刷卡效率。
在通过排除法选择出门禁卡的方案中，只能选择出一张门禁卡，此时若电子设备上设置有多张门禁卡时，而选择出的门禁卡无法完成刷卡时，需要用户将选择出的门禁卡切换到正确的门禁卡。这样造成模拟卡的切换速度慢，导致刷卡速度慢，从而降低了刷卡效率。
为解决上述技术问题，本申请另一些实施例还提供了一种模拟卡的切换方法。本申请实施例中，当电子设备进入预设区域内时采集当前位置指纹，计算当前位置指纹和预先采集的刷卡点指纹之间的相似度，若相似度大于门限值时，将激活卡切换为与刷卡点指纹匹配的模拟卡。本申请可基于相似度的变化，判断出电子设备是靠近刷卡点还是远离刷卡点，从而决定是否切换为与刷卡点指纹匹配的模拟卡。本申请实施例若判断出电子设备靠近刷卡点时，实现了提前预切卡，则当用户移动至刷卡点时电子设备可直接与NFC读卡器完成刷卡过程，从而提高了刷卡效率。
图16是本申请另一些实施例中模拟卡的切换方法的流程图，如图16所示，该方法包括：
步骤202、电子设备采集刷卡点的刷卡点指纹，并建立刷卡点指纹与目标卡的对应关系。
刷卡点设置有NFC读卡器，例如，NFC读卡器为小区门禁读卡器。
用户通过电子设备在刷卡点位置处首次进行刷卡时，电子设备采集刷卡点的周边网络设备的特征，并将刷卡点的周边网络设备的特征作为刷卡点指纹，该刷卡点指纹包括：周边网络设备的ID和该ID对应的信号参数。
采集的刷卡点指纹包括但不仅限于如下几种刷卡点指纹：
(1)若周边网络为WiFi网络时，周边网络设备的ID包括BSSID，对应的信号参数包括RSSI，则采集的刷卡点指纹包括WiFi网络的BSSID和RSSI，每个BSSID对应于一个RSSI。一般刷卡点的周边会存在多个WiFi网络设备，则可采集多个刷卡点指纹，即采集到多组BSSID和对应的RSSI。
(2)若周边网络为BT网络或者BLE网络时，周边网络设备的ID包括BSSID，对应的信号参数包括RSSI，则采集的刷卡点指纹包括BT网络或BLE网络的BSSID和RSSI，每个BSSID对应于一个RSSI。一般刷卡点的周边会存在多个BT网络或BLE网络，则可 采集多个刷卡点指纹，即采集到多组BSSID和对应的RSSI。
(3)若周边网络设备为Cell基站时，周边网络设备的ID包括CID，对应的信号参数包括信号值dBm，则采集的刷卡点指纹包括Cell基站的CID和信号值dBm，每个CID对应于一个信号值dBm。一般刷卡点的周边会存在多个Cell基站，则可采集多个刷卡点指纹，即采集到多组CID和对应的信号值dBm。
本步骤中，建立刷卡点指纹与目标卡的对应关系中，目标卡为在刷卡点的NFC读卡器进行刷卡操作的模拟卡。
步骤204、电子设备若进入特定区域，采集当前位置指纹。
本申请实施例，电子设备在进入特定区域后，可采用熄屏扫描的方式扫描周边网络，以采集到当前位置指纹。
本申请实施例中，可以刷卡点作为中心点建立地理围栏，地理围栏覆盖的区域为特定区域。电子准备进入地理围栏后，开始周期采集当前位置指纹。电子设备离开地理围栏后，停止采集当前位置指纹。
电子设备在电子围栏中移动时，电子设备周期性采集当前位置的周边网络设备的特征，并将当前位置的周边网络设备的特征作为当前位置指纹，该当前位置指纹包括：周边网络设备的ID和该ID对应的信号参数。
采集的当前位置指纹包括但不仅限于如下几种刷卡点指纹：
(1)若周边网络为WiFi网络时，周边网络设备的ID包括BSSID，对应的信号参数包括RSSI，则采集的当前位置指纹包括WiFi网络的BSSID和RSSI，每个BSSID对应于一个RSSI。一般刷卡点的周边会存在多个WiFi网络设备，则可采集多个刷卡点指纹，即采集到多组BSSID和对应的RSSI。
(2)若周边网络为BT网络或者BLE网络时，周边网络设备的ID包括BSSID，对应的信号参数包括RSSI，则采集的当前位置指纹包括BT网络或BLE网络的BSSID和RSSI，每个BSSID对应于一个RSSI。一般刷卡点的周边会存在多个BT网络或BLE网络，则可采集多个刷卡点指纹，即采集到多组BSSID和对应的RSSI。
(3)若周边网络设备为Cell基站时，周边网络设备的ID包括CID，对应的信号参数包括信号值dBm，则采集的当前位置指纹包括Cell基站的CID和信号值dBm，每个CID对应于一个信号值dBm。一般刷卡点的周边会存在多个Cell基站，则可采集多个刷卡点指纹，即采集到多组CID和对应的信号值dBm。
电子设备在电子围栏中移动时，周期性(即间隔时间)采集的当前位置指纹不停发生变化。
步骤206、电子设备计算当前位置指纹和刷卡点指纹之间的相似度。随着用户走动，间隔时间采集的当前位置指纹不停发生变化，因此计算所得的相似度也不停地变化。
把刷卡点指纹标记为F1，把标记为F2。
本步骤具体可包括：
步骤2062、查询出刷卡点指纹F1和当前位置指纹F2中相同的ID，并根据相同的ID形成相同设备集合[ID1,ID2…,IDn]，F1和F2中相同ID的个数为n。
步骤2064、根据F1中相同设备集合的ID对应的信号参数形成F1的第一信号参数集合[Q1,Q2…,Qn]；根据F2中相同设备集合的ID对应的信号参数形成F2的第二信号参数 集合[Q1’,Q2’…,Qn’]。
步骤2066、计算出相似度。
作为一种可选方案，根据相同设备集合的元素个数n和刷卡点指纹F1中的ID个数m，计算出相似度，其中，n<＝m。例如，相似度S＝1/(m-n+1)。n与m越接近，计算出的相似度越大。
作为另一种可选方案，根据第一信号参数集合和第二信号参数集合，计算出相似度。例如，相似度S＝1/(d+1)，d可以为第一信号参数集合[Q1,Q2…,Qn]和第二信号参数集合[Q1’,Q2’…,Qn’]之间的欧式距离，可通过欧氏距离公式对[Q1,Q2…,Qn]和[Q1’,Q2’…,Qn’]进行计算生成d。d越小，计算出的相似度越大。
作为另一种可选方案，根据相同设备集合的元素个数n、刷卡点指纹F1中的ID个数m、第一信号参数集合和第二信号参数集合计算出相似度。例如：相似度S＝k1/(m-n+1)+k2/(d+1)，其中，k1和k2为权重系数，k1+k2＝1。
本步骤中计算出的相似度的取值大于0且小于或等于1。
步骤208、基于相似度进行模拟卡的切换。
相似度用于表示当前位置与刷卡点位置之间的接近程度。相似度越大，表明电子设备越靠近刷卡点；相似度越小，表明电子设备越远离刷卡点。
若判断出相似度大于或等于门限值时，表示电子设备已经很靠近刷卡点，根据建立的刷卡点指纹与目标卡的对应关系，将激活卡切换为与刷卡点指纹匹配的目标卡。例如，激活卡为交通卡深圳通，目标卡为门禁卡。而后当用户移动至刷卡点时，由于电子设备已经预先完成了切换卡的过程，因此可以直接在刷卡点的NFC读卡器上进行门禁卡的刷卡操作，从而提高了刷卡速度，提高了刷卡效率。
若判断出相似度小于门限值时，表示电子设备已经很远离刷卡点，根据建立的刷卡点指纹与目标卡的对应关系，将激活卡切换为默认卡。例如，激活卡为门禁卡，默认卡为交通卡深圳通。
本实施例提供的技术方案中，电子设备采集刷卡点的刷卡点指纹并建立刷卡点指纹与目标卡的对应关系，若进入特定区域采集当前位置指纹，计算当前位置指纹和刷卡点指纹之间的相似度，基于相似度进行模拟卡的切换，实现了基于相似度自动进行预切换卡的操作，解决电子设备靠近NFC读卡器才能切换卡而导致的刷两次卡以及刷卡慢的问题，从而提高了刷卡效率。本申请实施例的方案由于是基于相似度自动进行预切换卡的操作，解决了电子设备上设置有多张门禁卡时自动进行预切换卡的问题，无需用户手动换卡，从而提高了刷卡效率。
