具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”等所区分的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说 明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”，一般表示前后关联对象是一种“或”的关系。
下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的近场通信NFC的信息显示方法进行详细地说明。
如图1所示，本申请实施例提供了一种近场通信NFC的信息显示方法。可选地，本申请实施例中的近场通信NFC的信息显示方法，可以应用于近场通信NFC的信息显示装置，也可以应用于电子设备，如移动终端等。
所述方法包括：
步骤11：接收目标装置发送的第一NFC信号；其中，所述目标装置包括NFC读卡器或NFC卡。
可选地，NFC卡可以包括但不限于：门禁卡、公交卡、银行卡等，或者NFC卡还可以是其他采用NFC技术的卡片等，本申请实施例不以此为限。
当目标装置为NFC卡时，NFC的信息显示装置或电子设备能够与所述NFC卡之间进行数据交互，其中，NFC卡可以主动或被动的与该装置或电子设备进行通信，该装置或电子设备可以对NFC卡的数据进行读取，如该装置或电子设备可以复制NFC卡的数据，或者读取NFC卡中的数据并执行相应操作(如NFC卡为门禁卡时，该装置或电子设备能够在读取所述NFC卡中的数据成功后，执行解除门禁的操作)。
以NFC卡为门禁卡，该装置或电子设备复制NFC卡的数据为例，门禁卡的类型可以是非加密门禁卡，也可以是加密门禁卡。
其中，非加密门禁卡其扇区数据是非加密的。通常复制此类门禁卡，只需要复制门禁卡的ID信息；加密门禁卡其扇区数据是经过加密的，需要通过秘钥校验成功后才能正常读取。复制此类门禁卡，不仅需要复制门禁卡的唯一标识码信息，还要复制门禁卡扇区的数据。
可选的，NFC读卡器可以包括但不限于：门禁读卡器、公交读卡器、银行卡读卡器等，或者NFC读卡器还可以是其他采用NFC技术的读卡器等，本申请实施例不以此为限。
当目标装置为NFC读卡器时，该NFC的信息显示装置或电子设备能够与所述NFC读卡器之间进行数据交互，其中该装置或电子设备中具有NFC 卡的数据，即该装置或电子设备可以模拟NFC卡与所述NFC读卡器之间进行数据交互。
步骤12：在所述第一NFC信号不符合所述第一NFC信号对应的目标响应条件的情况下，显示目标提示信息。
可选地，所述目标提示信息可以用于指示所述第一NFC信号不符合所述第一NFC信号对应的目标响应条件，当然该目标提示信息可以用于指示与所述目标装置之间的数据交互失败。
可选地，所述第一NFC信号不符合所述第一NFC信号对应的目标响应条件可以包括但不限于：第一NFC信号不符合协议条件，如不符合ISO14443协议的条件，第一NFC信号携带的信息内容不符合以TYPE A技术做出在场回应(Answer To Request Type A，ATQA)的指令内容，或不符合以TYPE B技术做出在场回应(Answer To Request Type B，ATQB)的指令内容；第一NFC信号携带的秘钥信息不符合解密得到的秘钥信息等。
其中，Type A技术是通过13.65MHz的射频载波传送信号。其采用方案为同步、改进的密勒(Miller)编码方式，通过100％幅移键控(amplitude shift keying，ASK)信号传送；当NFC卡向读卡器具传送信号时，通过调制载波传送信号。使用847kHz的副载波传送曼彻斯特(Manchester)编码。简单说，当表示信息“1”时，信号会有0.3微妙的间隙，当表示信息“0”时，信号可能有间隙也可能没有，与前后的信息有关。
Type B技术是在读卡器具向NFC卡传送信号时，通过13.65MHz的射频载波信号，采用的是异步、不归零(NRZ)编码方式，通过用10％ASK信号传送的方案；在NFC卡向读卡器具传送信号时，则是采用的二进制相移键控(binary phase shift keying，BPSK)编码进行调制。即信息“1”和信息“0”的区别在于信息“1”的信号幅度大，即信号强，信息“0”的信号幅度小，即信号弱。
以NFC卡为门禁卡，该装置或电子设备复制NFC卡的数据为例，门禁卡的类型可以是非加密门禁卡，也可以是加密门禁卡。
其中，非加密门禁卡其扇区数据是非加密的。采用该非加密门禁卡，或者是采用复制了非加密门禁卡的装置或电子设备刷门禁时，门禁卡或是该装 置或电子设备将唯一标识码信息发送给门禁机(或者称为门禁读卡器)，在门禁机验证该唯一标识码信息成功时，即可刷门禁成功，若验证该唯一标识码信息失败，即表示不符合所述第一NFC信号对应的目标响应条件。
其中，加密门禁卡其扇区数据是经过加密的，需要通过秘钥校验成功后才能正常读取。采用该加密门禁卡，或者是采用复制了加密门禁卡的装置或电子设备刷门禁时，门禁机会向加密门禁卡或是该装置或电子设备请求对应的扇区数据，请求成功才能正常刷开门禁，若请求失败，如无扇区数据或扇区数据不符合条件，则表示不符合所述第一NFC信号对应的目标响应条件。
可选地，NFC的信息显示装置或电子设备具有NFC模块，用于实现与目标装置的数据交互；其中，该NFC模块具有指令侦测单元，用于实现指令侦测。例如：在复制门禁卡数据或采用门禁卡或者是复制了门禁卡数据的装置或电子设备刷门禁的过程中，指令侦测单元可以实时侦测该装置或电子设备与目标装置之间的每个交互指令的正确性，在检测到在交互过程中的多个指令中存在不符合目标响应条件的执行时，触发异常上报，如上报给处理器，由处理器控制显示模块显示目标提示信息，以告知用户当前交互异常。
如图2所示，给出了一种指令侦测方法的流程图，具体包括：
步骤21：向外发出指令；例如：该指令可以是近场靠近指令，用于感应预定距离内的目标装置，当有目标装置接收该指令时可以反馈响应的应答指令。
步骤22：启动指令侦测单元；
步骤23：等待接收目标装置反馈的指令；
步骤24：判断是否在预定时长内接收到目标装置反馈的指令；若在预定时长内未接收到目标装置反馈的指令，则执行步骤25；若在预定时长内接收到目标装置反馈的指令，则执行步骤26；
步骤25：上报异常事件，流程结束；
步骤26：判断指令是否符合协议条件；若符合且未达到流程结束的条件，则执行步骤27；若符合且达到流程结束的条件，则流程结束；若不符合，则执行步骤25；
步骤27：向外发出指令；该指令可以是与目标装置的数据交互过程中的 指令，如用于握手连接的指令、密钥信息的认证等。
在本申请实施例中，接收目标装置发送的第一NFC信号；在所述第一NFC信号不符合所述第一NFC信号对应的目标响应条件的情况下，显示目标提示信息。这样，通过目标提示信息用于指示所述第一NFC信号不符合所述第一NFC信号对应的目标响应条件，来告知用户当前与NFC读卡器或NFC卡等目标装置的数据交互失败，从而避免了用户需要反复多次进行认证操作，导致操作时间和操作步骤的增加，从而有利于提高操作效率。
可选地，在所述目标装置为NFC卡的情况下，所述在所述第一NFC信号不符合所述第一NFC信号对应的目标响应条件的情况下，显示目标提示信息，包括：
在接收到所述第一NFC信号之后的预定时长内，未接收到携带有目标信息内容的第二NFC信号的情况下，显示第一提示信息；
其中，所述第一提示信息用于指示所述NFC卡是不符合第一预设协议条件的NFC卡。
例如：该NFC卡是门禁卡，NFC的显示装置或电子设备复制该门禁卡的数据时，如果该门禁卡是非ISO14443协议的门禁卡，或者该门禁卡是属于ISO14443协议的门禁卡，但是在数据交互过程中并未完全按照协议标准的内容进行数据交互的情况下，则可能发生复制失败。这种场景下，在复制门禁卡的过程中，检测NFC的显示装置或电子设备与门禁卡的数据交互指令任意一条指令不符合协议所规定的条件时，即触发复制门禁卡失败事件的上报。如在应用层界面通过交互显示提示信息，以告知用户复制门禁卡失败，例如提示信息的内容可以是“不支持此类门禁卡的复制操作”，如图3所示。
其中，检测NFC的显示装置或电子设备与门禁卡的数据交互指令中有任意一条指令不符合协议所规定的条件可以是：在接收到第一NFC信号之后，未在协议规定的预定时长内接收到携带有目标信息内容的第二NFC信号，则不符合协议所规定的条件。
如图4给出了复制门禁卡过程中，门禁卡与NFC的显示装置或电子设备之间的数据交互过程；具体可以包括：
NFC的显示装置或电子设备可以通过NFC天线发出寻卡指令，寻卡指令 用于侦测是否存在门禁卡同时启动装置或电子设备的指令侦测单元。
门禁卡接收到装置或电子设备发出的寻卡指令后作出回应，即向装置或电子设备反馈应答指令，即第一NFC信号。
指令侦测单元判断该门禁卡返回的应答指令的内容是否符合ATQA或ATQB指令内容，若不符合，则表示当前门禁卡不支持ISO14443协议，即不符合第一预设协议的条件，则停止复制门禁卡的操作，并上报异常事件。如在应用层界面通过交互显示提示信息，以告知用户所述NFC卡是不符合第一预设协议条件的NFC卡，复制门禁卡失败，例如提示信息的内容可以是“不支持此类门禁卡的复制操作”。如果在检测到有NFC片靠近即接收到NFC卡靠近的第一NFC信号之后，但在预设时长内未接受到NFC片反馈的ATQA或ATQB指令，则表示当前门禁卡不支持ISO14443协议，即不符合第一预设协议的条件，则停止复制门禁卡的操作，并上报异常事件。如在应用层界面通过交互显示提示信息，以告知用户所述NFC卡是不符合第一预设协议条件的NFC卡，复制门禁卡失败，例如提示信息的内容可以是“不支持此类门禁卡的复制操作”。
该实施例中，通过在与NFC卡的近场靠近信号的交互过程中，判断该NFC卡不符合协议条件，或者可以理解为NFC卡不是预定类型(如Type A或Type B类型)的NFC卡的情况下，可以直接终止复制流程，并通过显示提示信息的方式告知用户复制失败，可以减少用户反复多次进行复制操作，并且还可以通过具体显示NFC卡是不符合第一预设协议条件的NFC卡的方式，告知用户复制操作失败的原因，以便用户可以根据失败原因进行相应处理。
可选地，本申请的上述实施例还可以应用于刷卡过程中，如NFC的显示装置或电子设备可以是读卡器，该读卡器可以具有显示模块，用于显示提示信息，或者该读卡器可以与显示装置连接，用于发送携带该提示信息的指令至显示装置，并通过该显示装置显示所述提示信息等，本申请实施例不以此为限。
可选地，所述目标装置为NFC卡的情况下，所述接收目标装置发送的第一NFC信号的步骤，可以具体包括：在与所述NFC卡进行握手连接的交互 过程中，接收所述NFC卡发送的第一握手信号；
所述在所述第一NFC信号不符合所述第一NFC信号对应的目标响应条件的情况下，显示目标提示信息的步骤，可以具体包括：在所述第一握手信号不符合第一预设协议条件的情况下，显示第二提示信息；其中，所述第二提示信息用于指示所述NFC卡是不符合第一预设协议条件的NFC卡。
例如：该NFC卡是门禁卡，NFC的显示装置或电子设备复制该门禁卡的数据时，如果该门禁卡是非ISO14443协议的门禁卡，或该门禁卡是属于ISO14443协议的门禁卡，但是在数据交互过程中并未完全按照协议标准的内容进行数据交互的情况下，则可能发生复制失败。这种场景下，在复制门禁卡的过程中，检测NFC的显示装置或电子设备与门禁卡的数据交互指令中有任意一条指令不符合协议所规定的条件时，即触发复制门禁卡失败事件的上报。如在应用层界面通过交互显示提示信息，以告知用户复制门禁卡失败，例如提示信息的内容可以是“不支持此类门禁卡的复制操作”，如图3所示。
参见图4，在复制门禁卡过程中，门禁卡与NFC的显示装置或电子设备之间的数据交互过程；具体还可以包括：
在与门禁卡之间进行ISO14443协议的握手交互过程中，该握手交互过程中可能存在多个握手信号，即握手交互过程中可能存在多个指令的交互。指令侦测单元在该握手交互过程中检测到门禁卡反馈的任意一个握手信号内容不符合协议所规定的条件，如握手信号的内容与协议所规定的内容不一致，或者或握手信号的内容不是协议规定所包含的内容，即握手信号不符合第一预设协议的条件，则触发异常事件上报，表示不支持此类门禁卡的复制操作。如在应用层界面通过交互显示提示信息，以告知用户复制门禁卡失败，例如提示信息的内容可以是“不支持此类门禁卡的复制操作”，如图3所示。
可选地，在与门禁卡之间进行ISO14443协议的握手交互过程之前，还可以包括：
NFC的显示装置或电子设备可以通过NFC天线发出寻卡指令，寻卡指令用于侦测是否存在门禁卡同时启动装置或电子设备的指令侦测单元。
门禁卡接收到装置或电子设备发出的寻卡指令后作出回应，即向装置或电子设备反馈应答指令，即第一NFC信号。指令侦测单元判断该门禁卡返回 的应答指令的内容符合ATQA或ATQB指令内容的情况下，与门禁卡之间进行ISO14443协议的握手交互过程。
该实施例中，通过在与NFC卡的握手交互过程中，判断该NFC卡是不符合协议条件的NFC卡的情况下，可以直接终止复制流程，并通过显示提示信息的方式告知用户复制失败，可以减少用户反复多次进行复制操作，并且还可以通过具体显示NFC卡是不符合第一预设协议条件的NFC卡的方式，告知用户复制操作失败的原因，以便用户可以根据失败原因进行相应处理。
可选地，本申请的上述实施例还可以应用于刷卡过程中，如NFC的显示装置或电子设备可以是读卡器，该读卡器可以具有显示模块，用于显示提示信息，或者该读卡器可以与显示装置连接，用于发送携带该提示信息的指令至显示装置，并通过该显示装置显示所述提示信息等，本申请实施例不以此为限。
可选地，所述目标装置为NFC读卡器的情况下，所述接收目标装置发送的第一NFC信号的步骤，可以具体包括：在以第二NFC卡的数据与所述NFC读卡器进行握手连接的交互过程中，接收所述NFC读卡器发送的第二握手信号；
所述在所述第一NFC信号不符合所述第一NFC信号对应的目标响应条件的情况下，显示目标提示信息的步骤，可以具体包括：在所述第二握手信号不符合第二预设协议条件的情况下，显示第三提示信息；其中，所述第三提示信息用于指示所述第二NFC卡是不符合所述NFC读卡器对应的协议条件的NFC卡。
可选地，该NFC读卡器可以是门禁类型的读卡器，NFC的显示装置或电子设备具有门禁卡的数据，即具有模拟门禁卡的功能，在门禁读卡器与该装置或电子设备在ISO14443-3协议层握手建立连接的过程中，接收门禁读卡器反馈的握手信号，如果握手信号不符合ISO14443-3层的协议标准规范，及握手信号不符合第二预设协议条件，则触发上报刷门禁失败的事件。如应用层获取事件后通过交互显示提示信息，以告知用户NFC的显示装置或电子设备当前模拟的门禁卡是不符合所述NFC读卡器对应的协议条件的门禁卡，例如提示信息的内容可以是“非标准门禁、刷门禁失败”等，如图5所示。
如图6给出了刷门禁过程中，NFC的显示装置或电子设备与门禁读卡器之间的数据交互过程；具体可以包括：
门禁读卡器持续发出寻卡指令，该寻卡指令用于侦测是否存在门禁卡或模拟了门禁卡功能的装置或电子设备。
该装置或电子设备接收到门禁读卡器的寻卡指令后作出回应，即根据该寻卡指令反馈应答指令，并启动指令侦测单元。
门禁读卡器和终端设备进行ISO14443协议的握手交互过程，该握手交互过程中可能存在多个握手信号，即握手交互过程中可能存在多个指令的交互。指令侦测单元在该握手交互过程中检测到门禁卡反馈的任意一个握手信号内容不符合协议所规定的条件，如握手信号的内容与协议所规定的内容不一致，或者或握手信号的内容不是协议规定所包含的内容，或者门禁读卡器在接收到该装置或电子设备的应答指令(如ATQA指令)后，在40us内就回了防冲突(ANTICOLLISION)指令给该装置或电子设备，由于这个时间远小于协议规范定义的时间400us，所以对该装置或电子设备侧来说，相当于未收到门禁读卡器的任何指令，即握手信号不符合第二预设协议条件，则触发异常事件上报，表示非标准门禁，刷门禁失败。如在应用层界面通过交互显示提示信息，以告知用户该装置或电子设备所模拟的门禁卡功能未遵循ISO14443协议标准，导致刷门禁失败，例如提示信息的内容可以是“非标准门禁，刷门禁失败”，如图5所示。
该实施例中，通过在与NFC读卡器的握手交互过程中，判断所模拟的NFC卡是不符合NFC读卡器协议条件的NFC卡的情况下，可以直接终止刷卡流程，并通过显示提示信息的方式告知用户刷卡失败，可以减少用户反复多次进行复制操作，并且还可以通过具体显示NFC卡是不符合NFC读卡器的协议条件的NFC卡的方式，告知用户刷卡操作失败的原因，以便用户可以根据失败原因进行相应处理。
可选地，所述目标装置为读卡器的情况下，所述接收目标装置发送的第一NFC信号的步骤，可以具体包括：在以第二NFC卡的数据与所述NFC读卡器建立握手连接后，接收所述NFC读卡器发送的第一NFC信号，所述第一NFC信号携带有第一密钥信息；
所述在所述第一NFC信号不符合所述第一NFC信号对应的目标响应条件的情况下，显示目标提示信息的步骤，可以具体包括：根据所述第二NFC卡的数据确定第二密钥信息；在所述第一密钥信息与所述第二密钥信息不匹配的情况下，显示第四提示信息；其中，所述第四提示信息用于指示在与所述NFC读卡器建立握手连接后，以所述第二NFC卡的数据进行密钥认证失败。
可选地，当NFC读卡器是加密类型的读卡器，即需要在读取的NFC卡的数据满足相应加密协议的情况下，才能执行相应功能。
例如：加密类型的读卡器与NFC卡的数据交互过程可以是解密随机数的过程，如NFC卡或者是模拟了NFC卡功能的装置或电子设备可以通过内置的密钥尝试解密，得到第二密钥信息，如果该第二密钥信息与读卡器发送的第一密钥信息相匹配，则确定解密成功，则能够继续后续的数据交互流程。如果第二密钥信息与读卡器发送的第一密钥信息不匹配，则解密失败，则表明该NFC卡或者是模拟了NFC卡功能的装置或电子设备终端设备不具备正确的密钥，需要通过授权获取到密钥才能使得NFC读卡器执行相应功能，如该读卡器是门禁读卡器时，该NFC卡或者是模拟了NFC卡功能的装置或电子设备终端设备需要通过授权获取到密钥才能使得NFC读卡器解除门禁。在解密失败时，可以通过应用层显示提示信息，以告知用户NFC的显示装置或电子设备当前模拟的门禁卡是不具备正确的密钥，或者告知用户NFC的显示装置或电子设备当前模拟的门禁卡是未经授权的NFC卡，解密失败，例如提示信息的内容可以是“加密门禁，请先授权密钥”等，如图7所示。
如图8和图9，给出了解密过程中，NFC的显示装置或电子设备与门禁读卡器之间的数据交互过程；具体可以包括：
加密门禁读卡器持续发出寻卡指令，该寻卡指令用于侦测是否存在门禁卡或模拟了门禁卡的装置或电子设备。
该装置或电子设备收到加密门禁读卡器的寻卡指令后作出回应，即向加密门禁读卡器反馈应答指令，并启动指令侦测单元。
该装置或电子设备与加密门禁读卡器之间进行ISO14443协议层的握手交互，并通过ISO14443协议层的握手交互建立握手连接；加密门禁读卡器向 发送加密随机数，即第一密钥信息。
该装置或电子设备通过内置的密钥解密随机数，得到第二密钥信息。如果指令侦测单元侦测到解密失败，如无密钥无法进行解密，或者解密得到的第二密钥信息与第一密钥信息不匹配，则上报异常事件，显示提示用于，用于告知用户NFC的显示装置或电子设备当前模拟的门禁卡是未经授权的NFC卡，解密失败，例如提示信息的内容可以是“加密门禁，请先授权密钥”等，如图7所示。
如果解密成功，即第一密钥信息与第二密钥信息匹配，加密门禁读卡器收到成功的数据后，会进一步从该装置或电子设备中读取出门禁卡数据中的扇区数据，用于校验扇区内容，若校验成功，则表明刷门禁成功，此时加密门禁读卡器可以控制解除门禁。
该实施例中，对于加密类型的读卡器，在与NFC读卡器的建立握手连接后，在解密过程发生失败的情况下，可以直接终止刷卡流程，并通过显示提示信息的方式告知用户刷卡失败，可以减少用户反复多次进行复制操作，并且还可以通过具体显示当前读卡器是加密类型的读卡器，当前解密失败，需要授权密钥等方式，告知用户刷卡操作失败的原因，以便用户可以根据失败原因进行相应处理。
