刷卡方法、卡控制器、电子设备及存储介质
交叉引用
本申请基于申请号为“2021106144069”、申请日为2021年06月02日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此以引入方式并入本申请。
技术领域
本申请实施例涉及近场通信技术领域，特别涉及一种刷卡方法、卡控制器、电子设备及存储介质。
背景技术
为实现对集成多种通信协议的多张卡应用程序的电子设备的刷卡识别，现有一种方式为：对读卡器端进行硬件和软件升级改造，从而使得读卡器端能够根据协议类型不同从多种通信协议的多张卡应用程序中识别出对应协议的卡应用程序。此技术关注于读卡器端实现，需要全部替换当前的读卡器端，成本较大；而且当存在支持同一通信协议的多张卡应用程序时，由于读卡器端无法区分根据协议标签区分出是哪个卡应用程序发出的，因此，读卡器端无法从多个支持同一通信协议的卡应用程序中选取相应的卡应用程序。
为实现对集成多个支持同一通信协议的卡应用程序的电子设备的刷卡识别，现有另一种方式为：使用手持终端(比如手机)模拟智能卡的刷卡业务过程中，需要使用者在刷卡之前进行一系列操作，这些操作如下：首先，点亮手机屏幕，并进入选卡程序；然后，选择一张卡进行接下来的刷卡；最后，将手机靠近刷卡设备，利用选择的卡进行刷卡。也就是说，此种方式中需要用户在承载有卡应用程序的设备显示界面进行切卡操作，给用户使用模拟的智能卡进行刷卡产生了一些不便利，刷卡的便捷性较低。

本申请的实施方式还提供了一种卡控制器，包括：至少一个处理模块；以及，与所述至 少一个处理模块通信连接的存储模块；其中，所述存储模块存储有可被所述至少一个处理模块执行的指令，所述指令被所述至少一个处理模块执行，以使所述至少一个处理模块能够执行上述第一种刷卡方法。

具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合附图对本申请的各实施方式进行详细的阐述。然而，本领域的普通技术人员可以理解，在本申请各实施方式中，为了使读者更好地理解本申请而提出了许多技术细节。但是，即使没有这些技术细节和基于以下各实施方式的种种变化和修改，也可以实现本申请所要求保护的技术方案。
传统的各种智能卡，比如公交卡、银行卡、医保卡等，因为卡内含有芯片(芯片集成有卡控制器)而能被各种读卡器读取数据进行刷卡。常见的用于智能卡的芯片有两大类，一类是接触式刷卡，比如常见的插卡POS机。另一类是非接触式刷卡，其内含有类似NFC一类的非接触式数据传输控制芯片(含配套天线)，比如常见的靠近读卡机刷卡的公交卡。非接触式刷卡场景中，将这些常见的实体卡片功能，通过电子设备(例如手机)来模拟，这时候并没有实实在在的卡片存在，只是通过在电子设备内添加卡片的应用程序以“模拟”一张智能卡，这样同一个电子设备内可以通过NFC芯片(芯片集成有卡控制器)和安全元件的配合实现多种卡、多张卡的模拟，相当于在手机上安装了多张智能卡，可以在不同场合使用同一个电子设备以实现不同的刷卡认证、刷卡消费等行为。
本申请中刷卡方法所应用的场景是在非接触式刷卡场景下，所提及的卡应用程序可理解为集成在电子设备内的多张智能卡的应用程序，例如：公交卡应用程序、门禁卡应用程序、银行卡应用程序等。在理解了本申请刷卡方法所应用的场景以及卡应用程序的基本概念后，以下对本申请的刷卡方法进行具体说明：
本申请涉及一种刷卡方法，应用于卡控制器，包括：当检测到进入读卡器的射频场时， 进入选卡步骤，选卡步骤包括：根据内置的N个卡应用程序的优先级顺序，从本次选卡步骤中尚未被选取过的卡应用程序中选取优先级最高的卡应用程序，作为目标卡应用程序，N为大于或等于2的整数；调用目标卡应用程序，并利用目标卡应用程序与读卡器进行交互；在交互过程中，当检测到读卡器的射频场复位时，停用目标卡应用程序，并重复选卡步骤，直至N个卡应用程序中任一卡应用程序与读卡器交互成功，或者，N个卡应用程序在本次选卡步骤中均被选取过且均未交互成功。
当读卡器与卡应用程序交互失败后，读卡器的射频场复位，所述射频场复位是指射频场从开启—关闭—开启的这一过程，本申请中可利用读卡器与卡应用程序交互失败后，读卡器射频场复位这一特性，作为卡应用程序的切换条件。
具体的，当检测到进入读卡器的射频场时，进入选卡步骤，选卡步骤包括：根据内置的N个卡应用程序的优先级顺序，从本次选卡步骤中尚未被选取过的卡应用程序中选取优先级最高的卡应用程序，作为目标卡应用程序；调用目标卡应用程序，并利用目标卡应用程序与读卡器进行交互，若在交互过程中检测到读卡器的射频场复位，即检测到读卡器的射频场经历了从开启到关闭再到开启这一过程，则根据交互失败后读卡器射频场复位这一特性可知，当前被调用的卡应用程序与读卡器交互失败。因此，停用该被调用的目标卡应用程序，避免影响后续另一卡应用程序与读卡器之间的交互，重复选卡步骤，也就是说，调用另一个本次选卡步骤中尚未被选取过的卡应用程序，并利用另一个本次选卡步骤中尚未被选取过的卡应用程序与读卡器进行交互，直至N个卡应用程序中任一卡应用程序与读卡器交互成功，或者，N个卡应用程序在本次选卡步骤中均被选取过且均未交互成功，从而实现卡控制器自动切换卡应用程序以实现自适应刷卡，如此，既无需在设置卡应用程序的设备界面进行手动切卡操作，提高了刷卡的便捷性。且由于本申请中是在卡端进行改进，由卡端的卡控制器执行选卡步骤以实现自动切换卡应用程序，因此可适用于现有的读卡器端，无需对读卡器端进行改造便可从多张卡应用程序中选取出需识别的卡应用程序，能够降低成本。
下面对本实施方式的刷卡方法的实现细节进行具体的说明，以下内容仅为方便理解提供的实现细节，并非实施本方案的必须。
本申请刷卡方法的流程示意图如图1所示：
步骤101：根据内置的N个卡应用程序的优先级顺序，从本次选卡步骤中尚未被选取过的卡应用程序中选取优先级最高的卡应用程序，作为目标卡应用程序，N为大于或等于2的整数。
具体地说，在检测到进入读卡器的射频场时，从内置的N个卡应用程序中选取一个目标卡应用程序，该目标卡应用程序在进入该读卡器的射频场之后，在本次刷卡步骤中尚未被选 取过，也就是说，在进入该读卡器的射频场之后、在本次刷卡步骤中，该目标卡应用程序并未与读卡器尝试交互过。例如：一个电子设备中内置有深圳通公交卡应用程序、武汉通公交卡应用程序、门禁卡应用程序、招商银行卡应用程序和医保卡应用程序这5个卡应用程序，这5个卡应用程序在进入读卡器的射频场后、在本次刷卡步骤中，均未被选取并与读卡器尝试交互过，因此，可从这5个卡应用程序选取一个卡应用程序作为目标卡应用程序。而假使这5个卡应用程序中深圳通公交卡应用程序和门禁卡应用程序在本次选卡步骤中均被选取过，则需从招商银行卡应用程序、武汉通公交卡应用程序、和医保卡应用程序这3个卡应用程序中选取一个卡应用程序作为目标卡应用程序。
具体的在选取目标卡应用程序时，根据内置的N个卡应用程序的优先级顺序，从本次选卡步骤中尚未被选取过的卡应用程序中选取优先级最高的卡应用程序，作为目标卡应用程序。
本实施例中给出了以下三种优先级顺序的设置方式：
第一种，优先级顺序可随机设置。
第二种，根据N个卡应用程序中每个卡应用程序的历史交互成功次数，设置N个卡应用程序的优先级顺序，其中，卡应用程序的历史交互成功次数越高，卡应用程序的优先级越高。
具体地说，记录N个卡应用程序中每个卡应用程序的历史交互成功次数，一个卡应用程序的历史交互成功次数越多，表明该卡应用程序被使用的频率越高，那么该卡应用程序被用户使用的概率也就越大。该方案中卡应用程序的历史交互成功次数越高，卡应用程序的优先级越高，也就是说，在刷卡时，优先利用被用户使用的概率较大的卡应用程序作为目标卡应用程序与读卡器进行交互，可大大提升刷卡效率。
上述实现方式中，由卡控制器根据N个卡应用程序中每个卡应用程序的历史交互成功次数，来自动设置N个卡应用程序的优先级顺序。在实际应用中，也可由用户在具备卡控制器的电子设备的显示界面自行设置，以满足不同用户的个性化需求。
第三种，根据N个卡应用程序中每个卡应用程序对应的射频通信参数的优先级，设置N个卡应用程序的优先级顺序；其中，射频通信参数的优先级越高，与射频通信参数对应的卡应用程序的优先级越高。
具体地说，卡控制器预先获取根据N个卡应用程序中每个卡应用程序对应的射频通信参数，以得到N组射频通信参数。为N组射频通信参数设定优先级顺序，该方案中射频通信参数的优先级越高，与射频通信参数对应的卡应用程序的优先级越高，该方案中给出了另外一种确定N个卡应用程序的优先级顺序的实现方式，射频通信参数的优先级顺序可由控制器自主生成，如此，可自动生成N个卡应用程序的优先级顺序，无需用户设置或统计历史数据。
上述射频通信参数可以理解为：卡应用程序与读卡器之间建立空中接口连接所需使用的 通信参数，也就是说，卡应用程序的射频通信参数为用于与读卡器建立通信连接的参数。在具体实现中，射频通信参数可以包括但不限于：用户身份证明(User Identification，UID)、请求应答(Answer to Request，ATQ)、选择确认指令(Select Acknowledge，SAK)、选择应答(Answer To Select，ATS)、密钥KEY等。在为N组射频通信参数设定优先级顺序时，可根据上述射频通信参数中的任意一个参数的优先级顺序来确定该组射频通信参数的优先级顺序。
步骤102：调用目标卡应用程序，并利用目标卡应用程序与读卡器进行交互。
具体地说，在选取目标卡应用程序之后，调用该目标卡应用程序以利用该目标卡应用程序与读卡器进行交互。这里所说的调用目标卡应用程序可理解为是将目标卡应用程序运行在电子设备中。例如，深圳通公交卡应用程序、武汉通公交卡应用程序、门禁卡应用程序、招商银行卡应用程序和医保卡应用程序这5个卡应用程序在本次刷卡步骤中均未被选取并与读卡器尝试交互过，从深圳通公交卡应用程序、武汉通公交卡应用程序、门禁卡应用程序、招商银行卡应用程序和医保卡应用程序这5个卡应用程序中选取一个卡应用程序，例如深圳通公交卡应用程序作为目标卡应用程序，则调用深圳通公交卡应用程序，利用深圳通公交卡应用程序与读卡器进行交互。
需说明的是，本方案中目标卡应用程序与读卡器进行交互时，包括：利用目标卡应用程序与读卡器进行协议确认、协议确认成功后利用目标卡应用程序与读卡器进行key值认证、以及key值认证成功后利用目标卡应用程序与读卡器进行数据交互这三个步骤。当协议确认失败、key值认证失败或者数据交互失败时，读卡器的射频场复位。其中，当key值认证成功后利用目标卡应用程序与读卡器进行数据交互失败时，会多次重复利用目标卡应用程序与读卡器进行数据交互，从而避免由于网络原因导致数据交互失败。
步骤103：在交互过程中，判断是否检测到读卡器的射频场复位，当判定为是时，进入步骤104；当判定为否时，则结束该流程。
在选卡步骤中，当任意一个卡应用程序与读卡器交互失败，该卡应用程序会发送4bit的NACK信息至所述读卡器，读卡器在接收到该4bit的NACK信息时会执行射频场复位操作。在利用该目标卡应用程序与读卡器交互的过程中，通过判断是否检测到读卡器的射频场复位，便可确认目标卡应用程序与读卡器是否交互成功，射频场复位可理解为射频场的状态从开启到关闭，然后再到开启这一过程，若检测到射频场的状态经历了“开启—关闭—开启”这一变化过程，则可以确定读卡器的射频场复位。
若读卡器的射频场复位，则可以确定读卡器与卡应用程序交互失败，此时存在两种情况，一种为N个卡应用程序均已被选取过，另一种为N个卡应用程序还有在本次选卡步骤中尚未 被选取过的卡应用程序。因此，当检测到读卡器的射频场复位时，执行步骤104(停用目标卡应用程序，并判断N个卡应用程序是否在本次选卡步骤中均被选取过)以区分上述两种情况。
若读卡器的射频场并未复位，则可以确定卡应用程序与读卡器交互成功，此时可结束该流程。
在一个例子中，为了避免在未检测到读卡器的射频场复位时，立即结束刷卡流程而导致卡应用程序与读卡器之间未交互完成，那么在实际应用中，在执行一次检测读卡器的射频场复位时需持续一定的时间长度，该时间长度能够确保卡应用程序与读卡器之间的整个交互流程结束，如此，所探测到的结果才更加准确。该时间长度可根据实际需要进行设置，本实施例中不做具体限定。
步骤104：停用目标卡应用程序，并判断N个卡应用程序是否在本次选卡步骤中均被选取过。当判定为是时，该流程结束；当判定为否时，返回步骤101执行。
具体地说，在读卡器的射频场复位，也就是说，确定读卡器与卡应用程序交互失败后，停用目标卡应用程序，从而避免影响后续另一卡应用程序与读卡器之间的交互。此时，通过判断N个卡应用程序是否在本次选卡步骤中均被选取过，来确定N个卡应用程序是否在本次选卡步骤中均与读卡器尝试交互过。
在确定读卡器与卡应用程序交互失败后，且当N个卡应用程序在本次选卡步骤中均被选取过时，可以确定这N个卡应用程序中不存在可以与读卡器交互的卡应用程序，此时该刷卡流程可以结束。
当N个卡应用程序中存在在本次选卡步骤中尚未被选取过的卡应用程序，也就是说，N个卡应用程序中存在在本次选卡步骤中尚未与读卡器尝试交互过的卡应用程序，此时，需返回步骤101执行，继续从该N个卡应用程序中在本次选卡步骤中其他尚未被选取过的卡应用程序中选取一个卡应用程序作为目标卡应用程序。
在一个例子中，在N个卡应用程序在本次选卡步骤中均被选取过且均未交互成功之后，还包括：输出交互失败的信息。其中，所述输出交互失败的信息的具体形式可以是在包含卡控制器的电子设备的显示界面显示类似“交互失败”字样，也可以是，将交互失败的信息通过振动提示给用户，从而提示用户交互失败以避免用户多次刷卡。上述交互失败的信息的展示形式仅作举例，不应以此为限。
在一个例子中，在N个卡应用程序中任一卡应用程序与读卡器交互成功，或者，N个卡应用程序在本次选卡步骤中均被选取过且均未交互成功之后，还包括：将N个卡应用程序均重置为尚未被选取。
具体地说，在N个卡应用程序中任一卡应用程序与读卡器交互成功，或者，N个卡应用程序在本次选卡步骤中均被选取过且均未交互成功之后，将N个卡应用程序重置为尚未被选取，如此，在利用卡应用程序与另一读卡器尝试交互时，不会遗漏卡应用程序，如此能够保证刷卡结果的准确性。
可实现地，上述将N个卡应用程序重置为尚未被选取时，可通过去除标记的方式来实现。例如：在一次刷卡过程中，将N个卡应用程序中被选取过的卡应用程序标记为“已选取”，当N个卡应用程序均标记为“已选取”但均交互失败，或者N个卡应用程序中任一卡应用程序与读卡器交互成功时，去除N个卡应用程序中每个卡应用程序上的标记。上述区分卡应用程序在一次刷卡过程中是否被选取过的方式仅为举例说明，不以此为限。
在一个例子中，N个卡应用程序均使用同一通信协议，本方案中可实现对同一协议多卡应用的自适应刷卡。例如，本实施例中该N个卡应用程序均使用yula协议。当然，若支持其他协议的读卡器也具备在卡应用程序与读卡器交互时射频场复位这一特性，则本实施例中N个卡应用程序也可包含使用不用通信协议的卡应用程序。
上面各种方法的步骤划分，只是为了描述清楚，实现时可以合并为一个步骤或者对某些步骤进行拆分，分解为多个步骤，只要包括相同的逻辑关系，都在本专利的保护范围内；对算法中或者流程中添加无关紧要的修改或者引入无关紧要的设计，但不改变其算法和流程的核心设计都在该专利的保护范围内。
本申请还提供了另一种刷卡方法，包括：当检测到进入读卡器的射频场时，进入本次刷卡过程的协议确认步骤，所述协议确认步骤包括：从内置的M组卡应用程序中选取在本次刷卡过程中尚未被选取过的一组卡应用程序，作为目标组，其中，所述M组卡应用程序中任意两组卡应用程序所使用的通信协议类型不同，且每组卡应用程序中所有卡应用程序的通信协议类型相同，所述M为大于或等于2的整数；调用所述目标组中任意一个卡应用程序，并将所述目标组中被调用的卡应用程序的通信协议标签发送至读卡器，以供所述读卡器进行协议确认；若协议确认失败，则停用所述目标组中被调用的卡应用程序，并重复所述协议确认步骤，直至任一组卡应用程序中任意一个卡应用程序协议确认成功，或者所述M组卡应用程序在本次刷卡过程中均被选取过但均协议确认失败；若协议确认成功，则利用所述目标组中被调用的卡应用程序与所述读卡器进行key值认证；若key值认证成功，则利用所述目标组中被调用的卡应用程序与所述读卡器进行数据交互；若检测到所述读卡器的射频场复位，且所述目标组中包含N个卡应用程序，所述N为大于或等于2的整数时，进入本次刷卡过程的选卡步骤，所述选卡步骤包括：根据所述目标组中的N个卡应用程序的优先级顺序，从在本次刷卡过程中均未被选取过的卡应用程序中选取优先级最高的卡应用程序，作为目标卡应用程 序，所述N为大于或等于2的整数；调用所述目标卡应用程序，并利用所述目标卡应用程序与所述读卡器进行key值认证；若key值认证成功，则利用所述目标卡应用程序与所述读卡器进行数据交互；在交互过程中，当检测到所述读卡器的射频场复位时，停用所述目标卡应用程序，并重复所述选卡步骤，直至所述N个卡应用程序中任一卡应用程序与所述读卡器数据交互成功，或者，所述N个卡应用程序在本次刷卡过程中均被选取过且均未数据交互成功。
本方案中当检测到进入读卡器的射频场时，先进行本次刷卡过程的协议确认步骤，以从M组卡应用程序中确认出读卡器适用于哪一组卡应用程序的通信协议，当确认出读卡器适用的目标组后，先继续利用协议确认步骤中被调用的卡应用程序与读卡器进行key值认证、数据交互，若任意一个步骤失败，则表明目标组中被调用的卡应用程序与读卡器不适配，此时需进行选卡步骤。选卡步骤中，根据目标组中的N个卡应用程序的优先级顺序、从在本次刷卡过程中均未被选取过的卡应用程序中选取优先级最高的卡应用程序，作为目标卡应用程序。由于目标组中所有卡应用程序中的通信协议相同，因此，在协议确认成功后，无需利用目标卡应用程序与读器进行协议认证步骤，只需利用目标卡应用程序与读器进行key值认证、数据交互步骤即可。从目标组中N个卡应用程序中在本次刷卡过程中尚未被选取过的卡应用程序选取目标卡应用程序，利用目标卡应用程序与读卡器进行key值认证、数据交互，若在交互过程中检测到读卡器的射频场复位，则根据key值认证失败或数据交互失败后，读卡器射频场复位这一特性可知，当前目标卡应用程序与读卡器交互失败。因此，停用当前目标卡应用程序，并重复选卡步骤，也就是说，调用目标组中另一个在本次刷卡过程中尚未被选取过的卡应用程序，并利用另一个在本次刷卡过程中尚未被选取过的卡应用程序与读卡器进行key值认证、数据交互，直至N个卡应用程序中任一卡应用程序与读卡器数据交互成功，或者，N个卡应用程序在本次刷卡过程中均被选取过且均未数据交互成功，从而实现卡控制器自动切多种协议类型的卡应用程序、以及同一协议类型的多张卡应用程序以实现自适应刷卡，如此，既无需在设置卡应用程序的设备界面进行手动切卡操作，提高了刷卡的便捷性。且由于本申请中是在卡端进行改进，由卡端的卡控制器执行选卡步骤以实现自动切换卡应用程序，因此可适用于现有的读卡器端，无需对读卡器端进行改造便可从多种协议类型的卡应用程序、以及同一协议类型的多张卡应用程序中选取出需识别的卡应用程序，能够降低成本。
下面对本实施方式的刷卡方法的实现细节进行具体的说明，以下内容仅为方便理解提供的实现细节，并非实施本方案的必须。
本申请刷卡方法的流程示意图如图2所示：
步骤201：从内置的M组卡应用程序中选取在本次刷卡过程中尚未被选取过的一组卡应用程序，作为目标组，其中，M组卡应用程序中任意两组卡应用程序所使用的通信协议类型 不同，且每组卡应用程序中所有卡应用程序的通信协议类型相同，M为大于或等于2的整数。
具体地说，将使用不同协议类型的卡应用程序分类到一组卡应用程序中，使得每组卡应用程序中所有卡应用程序的通信协议类型相同，而任意两组卡应用程序所使用的通信协议类型不同，以便于后续步骤中根据不同组对协议类型进行确认。从M组卡应用程序中选取在本次刷卡过程中尚未被选取过的一组卡应用程序，如果一组卡应用程序中任意一个卡应用程序被选取过，则该组卡应用程序确定为被选取过。也就是说，在本次刷卡过程中尚未被选取过的一组卡应用程序中任意一个卡应用程序在本次刷卡过程中均被选取过。
值得说明的是，同一组卡应用程序指的是相同协议的卡应用程序，可能都是相同功能的卡应用程序比如交通卡应用程序，也可能是多种功能的卡应用程序。
具体的，在选取目标组卡应用程序时，根据内置的M组卡应用程序的优先级顺序，从本次选卡步骤中尚未被选取过的多组卡应用程序中选取优先级最高的一组卡应用程序，作为目标组。
本实施例中给出了以下两种优先级顺序的设置方式：
第一种，优先级顺序可随机设置。
第二种，根据M组卡应用程序中每组卡应用程序的历史交互成功次数，设置M组卡应用程序的优先级顺序，其中，该组卡应用程序的历史交互成功次数越高，该组卡应用程序的优先级越高。
具体地说，记录M组卡应用程序中每组卡应用程序的历史交互成功次数，一组卡应用程序的历史交互成功次数越多，表明该组卡应用程序被使用的频率越高，那么该组卡应用程序被用户使用的概率也就越大。该方案中一组卡应用程序的历史交互成功次数越高，表明该组卡应用程序的优先级越高，也就是说，在刷卡时，优先利用被用户使用的概率较大的一组卡应用程序作为目标组，可大大提升刷卡效率。
上述实现方式中，由卡控制器根据M组卡应用程序中每组卡应用程序的每个卡应用程序的历史交互成功次数之和，来自动设置M组卡应用程序的优先级顺序。在实际应用中，也可由用户在具备卡控制器的电子设备的显示界面自行设置，以满足不同用户的个性化需求。
步骤202：调用目标组中任意一个卡应用程序，并将目标组中被调用的卡应用程序的通信协议标签发送至读卡器，以供读卡器进行协议确认。
具体地说，调用目标组中任意一个卡应用程序，并利用目标组中被调用的卡应用程序的通信协议标签与读卡器进行协议确认。例如，当目标组中被调用的卡应用程序所使用的协议类型为yula协议时，则发送yula标签至读卡器以进行协议确认。
步骤203：判断协议确认是否成功，若判定失败，则进入步骤204；若判定成功，则进入 步骤205。
具体地说，若协议确认成功，则表明被调用的卡应用程序所使用的协议与读卡器适配，此时，需利用当前目标组卡应用程序与读卡器进行key值认证等其他步骤，即进入步骤205(判定利用目标组中被调用的卡应用程序与读卡器进行key值认证是否成功)。若协议确认失败，则表明被调用的卡应用程序所使用的协议与读卡器不适配，此时，需切换其他组的卡应用程序进行尝试，即进入步骤204(停用目标组中被调用的卡应用程序，并判断M组卡应用程序是否在本次刷卡过程中均被选取过)
步骤204：停用目标组中被调用的卡应用程序，并判断M组卡应用程序是否在本次刷卡过程中均被选取过，若判定为是，则该流程结束；若判定为否，则返回步骤201执行。
具体地说，协议确认失败后，停用目标组中被调用的卡应用程序，从而避免影响后续另一卡应用程序与读卡器之间的协议确认。此时，通过判断M组卡应用程序是否在本次刷卡过程中均被选取过，来确定M组卡应用程序是否均与读卡器尝试进行协议确认过。
若M组卡应用程序均与读卡器尝试进行协议确认过，则可以确定这M组卡应用程序中不存在与读卡器的通信协议相同的卡应用程序，此时该刷卡流程可以结束。
当M组卡应用程序中存在在本次刷卡过程中尚未被选取过的一组或多组卡应用程序，此时，需返回步骤201执行，继续从内置的M组卡应用程序中选取在本次刷卡过程中尚未被选取过的一组卡应用程序，作为目标组。
步骤205：判定利用目标组中被调用的卡应用程序与读卡器进行key值认证是否成功，若判定为成功，则进入步骤206；若判定失败，则进入步骤207。
具体地说，协议确认成功，则表明被调用的卡应用程序所使用的协议与读卡器适配，此时可继续利用被调用的卡应用程序与读卡器进行key值认证，若判定成功，则表明可利用该卡应用程序与读卡器进行数据交互，即进入步骤206(判定利用目标组中被调用的卡应用程序与读卡器进行数据交互是否成功)。若判定失败，则表明被调用的卡应用程序不能被读卡器所读取，此时如果当前目标组中还有其他卡应用程序，则需要切换其他卡应用程序进一步确认，即进入步骤207(判断目标组中的卡应用程序数目是否大于或等于2)。
步骤206：判定利用目标组中被调用的卡应用程序与读卡器进行数据交互是否成功，若判定为成功，则该流程结束；若判定失败，则进入步骤207。
具体地说，利用被调用的卡应用程序与读卡器进行key值认证成功后，可继续利用目标组中被调用的卡应用程序与读卡器进行数据交互，若数据交互成功，则表明被调用的卡应用程序与读卡器完成整个交互流程，此时可结束该流程。若数据交互失败，则需要切换其他卡应用程序进一步确认，即进入步骤207(判断目标组中的卡应用程序数目是否大于或等于2)。
步骤207：判断目标组中的卡应用程序数目是否大于或等于2。若确定为是，则进入步骤208；若确定为否，则该流程结束。
具体地说，目标组中被调用的卡应用程序与读卡器进行key值认证失败后，或者，目标组中被调用的卡应用程序与读卡器进行数据交互失败后，需进一步确认目标组中除该被调用的卡应用程序之外是否还有其他卡应用程序，即判断目标组中的卡应用程序数目是否大于或等于2。如果目标组中的卡应用程序数目大于或等于2，则需切换目标组中其他卡应用程序进一步确认，此时需进入步骤208(从目标组中的N个卡应用程序中选取一个在本次刷卡过程中尚未被选取过的卡应用程序，作为目标卡应用程序，N为大于或等于2的整数)。如果目标组中的卡应用程序数目仅为一个，由于该被调用的卡应用程序已经与读卡器整个交互流程失败，则表明目标组中不存在可被读卡器读取的卡应用程序，此时可结束该流程。
步骤208：根据目标组中的N个卡应用程序的优先级顺序，从在本次刷卡过程中均未被选取过的卡应用程序中选取优先级最高的卡应用程序，作为目标卡应用程序，N为大于或等于2的整数。
具体地说，从目标组中的N个卡应用程序中选取一个目标卡应用程序，该目标卡应用程序在进入该读卡器的射频场之后尚未被选取过，也就是说，该目标卡应用程序在本次交互过程中并未与读卡器尝试交互过。
具体的在选取目标卡应用程序时，根据内置的N个卡应用程序的优先级顺序，从本次选卡步骤中尚未被选取过的卡应用程序中选取优先级最高的卡应用程序，作为目标卡应用程序。
本实施例中给出了以下三种优先级顺序的设置方式：
第一种，优先级顺序可随机设置。
第二种，根据N个卡应用程序中每个卡应用程序的历史交互成功次数，设置N个卡应用程序的优先级顺序，其中，卡应用程序的历史交互成功次数越高，卡应用程序的优先级越高。
具体地说，记录N个卡应用程序中每个卡应用程序的历史交互成功次数，一个卡应用程序的历史交互成功次数越多，表明该卡应用程序被使用的频率越高，那么该卡应用程序被用户使用的概率也就越大。该方案中卡应用程序的历史交互成功次数越高，卡应用程序的优先级越高，也就是说，在刷卡时，优先利用被用户使用的概率较大的卡应用程序作为目标卡应用程序与读卡器进行交互，可大大提升刷卡效率。
上述实现方式中，由卡控制器根据N个卡应用程序中每个卡应用程序的历史交互成功次数，来自动设置N个卡应用程序的优先级顺序。在实际应用中，也可由用户在具备卡控制器的电子设备的显示界面自行设置，以满足不同用户的个性化需求。
第三种，根据N个卡应用程序中每个卡应用程序对应的射频通信参数的优先级，设置N 个卡应用程序的优先级顺序；其中，射频通信参数的优先级越高，与射频通信参数对应的卡应用程序的优先级越高。
具体地说，卡控制器预先获取根据N个卡应用程序中每个卡应用程序对应的射频通信参数，以得到N组射频通信参数。为N组射频通信参数设定优先级顺序，该方案中射频通信参数的优先级越高，与射频通信参数对应的卡应用程序的优先级越高，该方案中给出了另外一种确定N个卡应用程序的优先级顺序的实现方式，射频通信参数的优先级顺序可由控制器自主生成，如此，可自动生成N个卡应用程序的优先级顺序，无需用户设置或统计历史数据。
上述射频通信参数可以理解为：卡应用程序与读卡器之间建立空中接口连接所需使用的通信参数，也就是说，卡应用程序的射频通信参数为用于与读卡器建立通信连接的参数。在具体实现中，射频通信参数可以包括但不限于：用户身份证明(User Identification，UID)、请求应答(Answer to Request，ATQ)、选择确认指令(Select Acknowledge，SAK)、选择应答(Answer To Select，ATS)、密钥KEY等。在为N组射频通信参数设定优先级顺序时，可根据上述射频通信参数中的任意一个参数的优先级顺序来确定该组射频通信参数的优先级顺序。
步骤209：调用目标卡应用程序，并利用目标卡应用程序与读卡器进行key值认证。
具体地说，在选取目标卡应用程序之后，调用该目标卡应用程序以利用该目标卡应用程序与读卡器进行key值认证。需要说明的是，由于上述步骤中可以确定该目标组的通信协议与读卡器适配，则在切换该目标组中在本次刷卡过程中尚未被选取过的目标卡应用程序与读卡器尝试交互时，无需发送协议标签至读卡器，可直接跳过协议确认这一过程，直接利用目标卡应用程序与读卡器进行key值认证即可。
步骤210：判定利用目标卡应用程序与读卡器进行key值认证是否成功，若判定为成功，则进入步骤211；若判定失败，则进入步骤212。
具体地说，若判定成功，则表明可利用该目标卡应用程序与读卡器进行数据交互，即进入步骤211(判定利用目标卡应用程序与读卡器进行数据交互是否成功)。若判定失败，则表明该目标卡应用程序不能被读卡器所读取，此时如果当前目标组中还有在本次刷卡过程中其他尚未被选取过的卡应用程序，则需要切换在本次刷卡过程中其他尚未被选取过的卡应用程序进一步确认，即进入步骤212(停用目标卡应用程序，并判断N个卡应用程序是否在本次刷卡过程中均被选取过)。
步骤211：判定利用目标卡应用程序与读卡器进行数据交互是否成功，若判定为成功，则该流程结束；若判定失败，则进入步骤212。
具体地说，利用目标卡应用程序与读卡器进行key值认证成功后，可继续利用目标卡应 用程序与读卡器进行数据交互，若数据交互成功，则表明目标卡应用程序与读卡器完成整个交互流程，此时可结束该流程。若数据交互失败，则需要切换在本次刷卡过程中其他尚未被选取过的卡应用程序进一步确认，即进入步骤212(停用目标卡应用程序，并判断N个卡应用程序是否在本次刷卡过程中均被选取过)。
步骤212：停用目标卡应用程序，并判断N个卡应用程序是否在本次刷卡过程中均被选取过。若判定为是时，该流程结束；若判定为否，返回步骤208执行。
具体地说，由于在卡应用程序与读卡器的key值认证失败或数据交互失败后，读卡器的射频场复位。因此，当探测到读卡器的射频场复位，则可以确认卡应用程序与读卡器的key值认证失败或数据交互失败，当N个卡应用程序在本次刷卡过程中均被选取过时，可以确定这N个卡应用程序中不存在可以被读卡器读取的卡应用程序，此时该刷卡流程可以结束。
当N个卡应用程序中存在在本次刷卡过程中尚未被选取过的卡应用程序，也就是说，N个卡应用程序中存在尚未与读卡器尝试交互过的卡应用程序，此时，需返回步骤208执行，继续从该N个卡应用程序中在本次刷卡过程中其他尚未被选取过的卡应用程序中选取一个卡应用程序作为目标卡应用程序。
在一个例子中，在N个卡应用程序在本次刷卡过程中均被选取过且均未交互成功之后，或者，M组卡应用程序中在本次刷卡过程中均被选取过但均协议确认失败之后还包括：输出交互失败的信息。其中，输出交互失败的信息的具体形式可以是在包含卡控制器的电子设备的显示界面显示类似“交互失败”字样，也可以是，将交互失败的信息通过振动提示给用户，从而提示用户交互失败以避免用户多次刷卡。上述交互失败的信息的展示形式仅作举例，不应以此为限。
在一个例子中，在N个卡应用程序中任一卡应用程序与读卡器交互成功，或者，N个卡应用程序在本次刷卡过程中均被选取过且均未交互成功之后，还包括：将N个卡应用程序均重置为尚未被选取。
具体地说，在N个卡应用程序中任一卡应用程序与读卡器交互成功，或者，N个卡应用程序在本次刷卡过程中均被选取过且均未交互成功之后，将N个卡应用程序重置为尚未被选取，如此，在利用卡应用程序与另一读卡器尝试交互时，不会遗漏卡应用程序，如此能够保证刷卡结果的准确性。
可实现地，上述将N个卡应用程序重置为尚未被选取时，可通过去除标记的方式来实现。例如：在一次刷卡过程中，将N个卡应用程序中被选取过的卡应用程序标记为“已选取”，当N个卡应用程序均标记为“已选取”但均交互失败，或者N个卡应用程序中任一卡应用程序与读卡器交互成功时，去除N个卡应用程序中每个卡应用程序上的标记。上述区分卡应用 程序在一次刷卡过程中是否被选取过的方式仅为举例说明，不以此为限。
在一个例子中，在任一组卡应用程序中任意一个卡应用程序协议确认成功，或者M组卡应用程序在本次刷卡过程中均被选取过但均协议确认失败之后，还包括：将M组卡应用程序均重置为尚未被选取。如此，在利用该M组卡应用程序与另一读卡器尝试交互时，不会遗漏M组卡应用程序中的任意一组，能够保证刷卡结果的准确性。具体的，区分M组卡应用程序中任意一组卡应用程序是否被选取的方式也可通过设置或去除标记的方式实现，在此不再赘述。
上面各种方法的步骤划分，只是为了描述清楚，实现时可以合并为一个步骤或者对某些步骤进行拆分，分解为多个步骤，只要包括相同的逻辑关系，都在本专利的保护范围内；对算法中或者流程中添加无关紧要的修改或者引入无关紧要的设计，但不改变其算法和流程的核心设计都在该专利的保护范围内。
