Definitions

  • the present application relates to the field of terminals, and in particular to an automatic activation method and terminal for Near Field Communication (NFC) applications.
  • NFC Near Field Communication
  • NFC is a short-range wireless communication technology based on a 13.56 megahertz (MHz) carrier frequency that allows non-contact point-to-point data transmission between devices. Since NFC has high security, it has become more and more popular and accepted by the public in recent years. Among them, the development of NFC-capable terminals is particularly rapid. Terminals with NFC function can work in three modes: card reader mode, card emulation mode, and point-to-point mode. The most used is the card simulation mode, that is, the terminal can be simulated as a non-contact integrated circuit (Integrated Circuit, IC) card, and the user can interact with the card reader by holding the terminal to complete the bank card, bus card or card Access control cards and other operations bring a lot of convenience to life.

  • One NSE can carry multiple NFC applications simultaneously.
  • the terminal can simulate the corresponding contactless IC card to interact with the card reader.
  • the NFC application can be manually activated by the user.
  • NFC applications can also be activated automatically by the terminal.

Description

一种NFC应用的自动激活方法及终端
本申请要求于2018年12月19日提交中国国家知识产权局、申请号为201811561669.2、申请名称为“一种NFC应用的自动激活方法及终端”以及于2018年11月1日提交中国专利局、申请号为201811294647.4、申请名称为“一种NFC应用的激活方法及终端”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及终端领域，尤其涉及一种近距离无线通信(Near Field Communication，NFC)应用的自动激活方法及终端。
背景技术
NFC是一种基于13.56兆赫兹(MHz)载波频率的近距离无线通信技术，允许设备之间进行非接触式点对点数据传输。由于NFC具有较高的安全性，因此，近年来越来越被大众欢迎和接受。其中具备NFC功能的终端的发展尤为迅速。具备NFC功能终端可以工作于三种模式：读卡器模式，卡模拟模式，点对点模式。使用最多的是卡模拟模式，即终端可以模拟为一张非接触集成电路(Integrated Circuit，IC)卡，用户手持终端便可与读卡器进行交互，以完成刷银行卡、刷公交卡或刷门禁卡等操作，给生活带来很多便利。
终端在模拟为非接触IC卡与读卡器进行交互之前，需下载对应的NFC应用到安全单元(Security Element，SE)中。SE可以为NFC应用的运行提供安全的执行环境，为其敏感数据提供安全的存储环境。一个SE中可同时承载多个NFC应用。在SE中承载的NFC应用被激活时，终端便可模拟为对应的非接触IC卡与读卡器进行交互。其中，NFC应用可由用户手动激活。NFC应用也可由终端自动激活。具体的，终端可在接收到读卡器发送的交易指令后，可以根据交易指令中携带的应用标识符(Application Identifier，AID)来判别该交易指令访问的是SE中承载的哪个NFC应用，并自动将交易指令访问的NFC应用激活。
但是，由于目前NFC应用没有形成统一的规范，移动运营商、电子设备制造商、应用生产商等多方均在主导定制SE，因此，一个终端可能有多个SE。通常，SE只有处于激活状态下时，终端才可以根据交易指令携带的AID自动激活该交易指令所要访问的NFC应用。而目前终端同时仅有一个SE处于激活状态。这样，在交易指令访问的是处于未激活状态的SE中承载的NFC应用时，终端是无法自动激活对应NFC应用的。这种情况下，用户只能手动选择激活对应的NFC应用，方可与读卡器完成交互。因此，在终端有多个SE时，如何自动激活交易指令所访问的NFC应用，已成为本领域技术人员研究的重点课题。

NFC应用：是用于实现近距离通信的应用程序，其具备用于模拟非接触IC卡的仿真功能。根据应用场景的不同，NFC应用可以分为不同的类型。如，公交类应用、门禁类应用、银行卡类应用等。其中，NFC应用具有AID，但并不是所有的NFC应用都会使用AID。使用AID的NFC应用支持AID识别，即终端能够根据交易指令中携带的AID识别出交易指令所访问的NFC应用。
终端实现卡模拟需要包括三个功能实体，分别为：设备主机(device host，DH)，NFC控制器(NFC controller，NFCC)和SE。其中：
DH：可以负责NFCC的管理，如初始化、配置和电源管理等。
NFCC：可以负责通过天线进行数据的物理传输。其中，DH可以包含在终端的主芯片中，NFCC可以包含在终端的NFC芯片中。
SE：可以负责为NFC应用提供安全执行环境(如认证、授权等)以及敏感数据存储的环境。SE是一个安全单元芯片。SE中可同时承载多个NFC应用。
终端可以有一个或多个SE。如果终端有多个SE，则这些SE可以以不同的形式存在。例如，如图1所示，终端有三个SE。这三个SE分别可以为：以用户标识模块(subscriber identification module，SIM)卡形式存在的SE 1，与NFC芯片一起封装的SE 2，以及以终端的主芯片(如图1中所示的应用处理器(application processor，AP))形式存在的inSE。对于inSE而言，SE的硬件，如图1所示的SE 3部署在位于云端的服务器中。
当然，上述SE只是作为示例，在本实施例中，SE还可以以其他形式存在于终端。如，以SD卡形式存在的SE。又如，以通用集成电路卡(Universal Integrated Circuit Card，UICC)形式存在的SE等等，本实施例对此不作限制。
一般的，SE只有处于激活状态下时，终端才可以自动激活接收到的交易指令所访 问的NFC应用。但是，由于终端同时仅有一个SE处于激活状态。这样，在终端有多个SE的情况下，如果交易指令所访问的是处于未激活状态的SE中承载的NFC应用，则终端是无法自动激活对应NFC应用的。例如，结合上述图1，以当前处于激活状态的是以SIM卡形式存在的SE 1为例。在终端靠近读卡器(或POS机具)时，终端可以接收到读卡器(或POS机具)发送的交易指令。如果该交易指令所访问的NFC应用承载在SE 1中，则终端可以自动激活对应的NFC应用，以完成交易。如果该交易指令所访问的NFC应用没有承载在SE 1中，而是承载在SE 2或SE 3中，则终端是无法自动激活交易指令所访问的NFC应用的。此时，只能通过用户手动激活对应的NFC应用才能完成交易。
本实施例提供一种NFC应用的自动激活方法，该方法可以应用于有多个SE的终端，该终端具备NFC功能。本实施例提供的方法，在终端有多个SE时，能够自动激活的交易指令所要访问的NFC应用。
举例来说，本实施例中所述的终端，可以为手机、平板电脑、桌面型、膝上型、手持计算机、笔记本电脑、超级移动个人计算机(Ultra-mobile Personal Computer，UMPC)、上网本、蜂窝电话、以及个人数字助理(Personal Digital Assistant，PDA)、可穿戴式设备(如智能手表)、增强现实(augmented reality，AR)\虚拟现实(virtual reality，VR)设备等设备，本实施例对该设备的具体形式不做特殊限制。

对于已经下载到终端的SE中的NFC应用(如，本申请中的第二NFC应用也可以是该NFC应用)，如出厂时已经下载到终端的SE中的NFC应用。如果该NFC应用并未下载到默认处于激活状态的SE中，终端可以确定该NFC应用的AID是否包含在上述白名单中。如果确定该NFC应用的AID包含在白名单中，那么终端可以将该NFC应用由当前的SE中转移到默认处于激活状态的SE中。例如，结合上述示例和表1所示，终端出厂时下载了某银行的银行卡应用到终端的SE 2中，其AID为AID 2。终端确定出该银行卡应用的AID 2包含在终端存储的白名单中。终端可以将银行卡应用由SE 2转移到SE 1中。
之后，在终端靠近读卡器或POS机具时，终端可以接收交易指令(如，本申请中的第一交易指令可以是该交易指令)。该交易指令中可以包括AID。终端根据交易指令中包括的AID，便可以在默认处于激活状态的SE中查找到对应的NFC应用并自动激活该NFC应用。示例性的，在用户手持终端靠近读卡器(或POS机具)时，读卡器(或POS机具)可以发送携带AID的交易指令。终端的NFCC可以接收该交易指令。终端的NFCC可以将接收到的交易指令发送至默认处于激活状态的SE(如上述SE 1)。默认处于激活状态的SE接收到交易指令后，可以根据该交易指令中携带的AID，自动运行该AID所标识的NFC应用，并执行该交易指令。
例如，结合上述示例，在下载西安的公交卡应用时，终端将其下载到了默认处于激活状态的SE 1中。西安的公交卡应用的AID为AID 1。用户在手持终端靠近西安公交车上的POS机具时，该POS机具可以发送携带AID 1的交易指令，该交易指令用于指示扣除用户公交卡的金额1元钱。终端的NFCC收到该交易指令时，可以将该交易指令发送至SE 1。SE 1可以根据接收到的交易指令中携带的AID 1确定POS机具所访问的NFC应用为西安的公交卡应用。SE 1可以自动运行该西安的公交卡应用，并扣除1元钱。
又例如，结合上述示例，终端将出厂默认下载在SE 2的银行卡应用转移到了默认处于激活状态的SE 1中。该银行卡应用的AID为AID 2。用户在手持终端靠近POS 机具时，该POS机具可以发送携带AID 2的交易指令，该交易指令用于指示扣除用户银行卡的金额268元钱。终端的NFCC收到该交易指令时，可以将该交易指令发送至SE 1。SE 1可以根据接收到的交易指令中携带的AID 2，确定POS机具所访问的NFC应用为银行卡应用。SE 1可以自动运行该银行卡应用，并扣除268元钱。
在本实施例中，如果NFC应用不是支持AID识别的NFC应用，那么终端可以将该NFC应用下载到SE 1中，也可以将该NFC应用下载在终端的其他SE中，如SE 2或SE 3中。
在其他一些实施例中，上述特定的NFC应用可以是用户经常用到的NFC应用。也就是说，可以将用户经常用到的NFC应用均承载在终端的默认处于激活状态的SE中。其中，本申请中的第一SE可以是该默认处于激活状态的SE。
示例性的，终端可以获取终端中的NFC应用的使用频率。例如，终端可以统计用户在一段时间内手动激活NFC应用的次数来获取其使用频率。如果终端获取到某NFC应用的使用频率大于预定的阈值，但该NFC应用当前并未承载在默认处于激活状态的SE中，则终端可以将该NFC应用由当前的SE中转移到默认处于激活状态的SE中。
示例性的，终端还可以统计用户经常使用该NFC应用的时间和/或地理位置等信息，以便后续在接收到交易指令(如，本申请中的第二交易指令可以是该交易指令)时，可以根据这些信息确定用户当前使用终端的意图是否是使用该NFC应用。在确定用户使用终端的意图是使用该NFC应用时，可以自动将其激活。在一些实施例中，终端可以通过各种定位技术来获取地理位置。例如，终端可以通过终端中的GPS来获取用户所处的地理位置。
例如，结合图1，以以SIM卡形式存在的SE 1默认处于激活状态为例。如图3中的(a)所示，终端的与NFC芯片一起封装的SE 2中承载了某NFC应用，如车钥匙应用301。终端根据用户在一段时间内手动激活该车钥匙应用301的次数，获取到该车钥匙应用301的使用频率为频率1。终端判断该频率1是否大于预定的阈值。如果该频率1大于预定的阈值，终端可以将该车钥匙应用301由SE 2中转移到默认处于激活状态的SE 1中，如图3中的(b)所示。另外，终端还统计出了用户在7:30-7:50这个时间段内经常使用该车钥匙应用301。那么如果终端接收到了交易指令，可以在获取到当前***时间(或者说是，接收到交易指令的时间)处于7:30-7:50这个时间段内时，自动激活该车钥匙应用301。也就是说，可以在当前***时间处于7:30-7:50这个时间段内时，由默认处于激活状态的SE 1自动运行该车钥匙应用301。这样，在用户使用手机靠近车门时，无需用户手动激活车钥匙应用301，可打开车门。
又例如，结合图1，以以SIM卡形式存在的SE 1默认处于激活状态为例。如图3中的(a)所示，终端的以终端的AP形式存在的inSE中承载了某NFC应用，如门禁卡应用302。终端根据用户在一段时间内手动激活该门禁卡应用302的次数，获取到该门禁卡应用302的使用频率为频率2。终端判断该频率2是否大于预定的阈值。如果该频率2大于预定的阈值，终端可以将该门禁卡应用302由inSE中转移到默认处于激活状态的SE 1中，如图3中的(b)所示。另外，终端还统计出了用户在18:00-18:30这个时间段内，且某个地理位置范围内(如该地理位置范围是用户的家)经常使用该门禁卡应用302。那么如果终端接收到了交易指令，可以在获取到当前***时间(或 者说是，接收到交易指令的时间)处于18:00-18:30这个时间段内，且当前所处的地理位置(或者说是，接收到交易指令时的地理位置)位于上述地理位置范围内时，自动激活该门禁卡应用302。也就是说，可以在当前***时间处于18:00-18:30这个时间段内，且当前地理位置处于地理位置范围内时，由默认处于激活状态的SE 1自动运行该门禁卡应用302。这样，在用户使用手机靠近房间门时，无需用户手动激活门禁卡应用302，可打开房间门。
当然，对于承载在默认处于激活状态的SE中的NFC应用，终端也可以统计出用户经常使用该NFC应用的时间和/或地理位置等信息，以便后续可以根据这些信息确定用户当前使用终端的意图是否是使用该NFC应用。若是，则可以将该NFC应用的自动激活。
又示例性的，终端可以在下载NFC应用时，将NFC应用的相关信息和NFC应用的句柄对应存储在该默认处于激活状态的SE的路由表中。终端在接收到交易指令后，可以根据该路由表，从该默认处于激活状态的SE承载的NFC应用中确定出交易指令所访问的NFC应用，并自动将其激活，以便完成交易。需要说明的是，根据路由表来确定交易指令所访问的NFC应用的具体过程，可参考下述实施例中对应内容的具体描述，此处不再详细赘述。
在本申请其他一些实施例中，在终端有多个SE(如三个SE)的场景下，会存在一个SE默认处于激活状态，其他的SE处于未激活状态。在本实施例中，终端可以根据用户使用NFC应用的场景来实现对应NFC应用的自动激活。
示例性的，结合图1，以以SIM卡形式存在的SE 1默认处于激活状态，SE 2和SE 3处于未激活状态为例。终端的NFCC在接收到交易请求后，可以根据使用场景来确定交易请求所访问的NFC应用。如果交易请求所访问的NFC应用承载在SE 1中，则终端的NFCC可以将接收到的交易请求传输至该SE 1，以便该SE 1自动激活对应的NFC应用，进而完成交易。如果交易请求所访问的NFC应用不是承载在SE 1中，而是承载在处于未激活状态的SE，如SE 2中，那么终端可以将该SE 1去激活，并将SE 2激活。这样，终端的NFCC可以将接收到的交易请求传输至当前处于激活状态的SE 2。SE 2根据接收到的交易指令，可以自动激活对应的NFC应用，进而完成交易。
例如，结合图1，以以SIM卡形式存在的SE 1默认处于激活状态，SE 2和SE 3处于未激活状态为例。终端的SE 1中承载了深圳的公交卡应用，SE 2中承载了西安的公交卡应用。终端可以根据用户所处的地理位置来实现对应NFC应用的自动激活。当用户手持终端靠近公交车上的POS机具时，终端的NFCC可以接收POS机具发送的交易指令。终端在接收到交易指令后，可以获取用户当前所处的地理位置。如果获取到的地理位置表明用户当前处于深圳，则终端的NFCC可以将接收到的交易指令传输至SE 1。此时，SE 1自动激活深圳的公交卡应用，并执行该交易指令，如从该公交卡应用中扣除相应的金额。如果获取到的地理位置表明用户当前处于西安，则终端可以将SE 1去激活，将SE 2激活。终端的NFCC可以将接收到交易指令传输至SE 2。SE 2接收到交易指令后，可以自动激活西安的公交卡应用，并执行该交易指令，以便完成交易。
在本申请另外一些实施例中，在终端下载有多个NFC应用的场景下，终端可以根 据部署在互联网的服务器发送的推荐信息，来确定出需要自动激活的NFC应用，并将其自动激活。该服务器发送的推荐信息可以是根据其他用户的终端上报的信息确定的，该信息可以用于指示该终端在某场景下，使用了某NFC应用。一般的，大多数用户在某时间、地点均使用了某NFC应用。这些用户的终端可以将用于指示在该时间、地点使用了该NFC应用的信息上报至服务器。在用户在该时间到达该地点后，用户的终端可以接收到服务器发送的推送消息，该推送消息用于指示终端向用户推荐使用对应的NFC应用。终端可以根据该推送消息，自动激活对应的NFC应用。
例如，服务器根据大多数用户上报的信息确定出在某地方的星巴克，大家都使用了招商银行的银行卡应用。某用户的终端中下载了招商银行的银行卡应用。当用户来到该地方的星巴克时，终端可以接收到的服务器发送的推送消息，终端根据该推送消息，可以自动激活终端中的招商银行的银行卡应用。在一些实施例中，如图4所示，终端在接收到推送消息后，可以显示提示窗口，该提示窗口中包括提示信息401，该提示信息401用于提示用户将自动激活招商银行的银行卡应用。在一些实施例中，该提示窗口中还可以包括确定按钮402和取消按钮403。当用户想要使用该招商银行的银行卡应用时，可以对确定按钮402执行点击操作。响应于该点击操作，终端可以自动激活该应用。如果用户不想使用该招商银行的银行卡应用时，可以对取消按钮403执行点击操作。响应于该点击操作，终端则不激活该应用。在一些实施例中，当该招商银行的银行卡应用承载在处于未激活状态的SE中时，终端在接收到推送消息后，可以先将承载该银行卡应用的SE激活。
在本申请另外一些实施例中，在终端有多个SE(如三个SE)的场景下，用户在手持终端靠近读卡器(或POS机具)后，终端可以接收读卡器(或POS机具)发送的交易指令。终端根据接收到的交易指令，确定交易指令所访问的NFC应用承载在终端的多个SE中的哪个SE。如将承载交易指令所访问的NFC应用的SE称为目标SE。在确定出目标SE后，可以将接收到的交易指令传输至该目标SE。目标SE根据接收到的交易指令，可以从目标SE承载的NFC应用中确定交易指令所访问的NFC应用，如将交易指令所访问的NFC应用称为目标NFC应用。目标SE可以自动激活该目标NFC应用。也就是说，目标SE可以自动运行该目标NFC应用，并执行读卡器(或POS机具)的交易指令，以便完成交易。
在本实施例中，所述的交易指令可以是任何类型读卡器(如，手持移动读卡器，固定读卡器)或任何类型POS机具(如，手持移动POS机具，固定POS机具)所发出指令。其可以是各种类型或各种帧格式的指令。如，交易指令可以是应用协议数据单元(Application Protocol Data Unit，APDU)帧格式、单字节短帧格式、长帧格式等帧格式的指令。又如，交易指令可以是14443类型(TYPE)A，14443TYPE B，国际标准化组织(International Standard Organization，ISO)18092，ISO15693等类型的指令。
在一些实施例中，如果终端确定出的目标SE处于激活状态，则终端在确定出目标SE后，可以将接收到的交易指令传输至该目标SE。如果终端确定出的目标SE处于未激活状态，则终端在确定出目标SE后，可以将该目标SE激活，然后将接收到的交易指令传输至该目标SE。当然，如果目标SE处于未激活状态，终端的其他SE处 于激活状态，终端还可以将处于激活状态的其他SE去激活。
在一些实施例中，终端可以根据终端维护的第一路由表来确定交易指令所访问的NFC应用承载在终端的多个SE中的哪个SE。即终端可以根据第一路由表确定目标SE。该第一路由表中可以包括：终端安装的所有NFC应用相关信息与承载每个NFC应用的SE的SE标识(但不限于SE标识。如，承载每个NFC应用的SE与NFCC之间的物理通道标识或者逻辑通道标识等)的对应关系。以下实施例中，以第一路由表中包括终端安装的所有NFC应用相关信息与承载每个NFC应用的SE的SE标识的对应关系为例进行介绍。
终端可以根据终端维护的第二路由表从目标SE承载的至少一个NFC应用中确定交易指令所访问的NFC应用，即确定目标NFC应用。终端可以为终端中的每个SE维护一个第二路由表。该第二路由表中可以包括：该SE中承载的每个NFC应用的相关信息与该NFC应用的句柄(handle)的对应关系。
其中，终端的多个SE中的每个SE可以承载至少一个NFC应用。NFC应用可以是终端由服务器处下载的。在下载NFC应用时，终端可以分别在上述第一路由表和第二路由表中配置该NFC应用对应的路由信息。之后，终端根据这些路由信息便可以确定出目标NFC应用，并自动将其激活，以便完成交易。
示例性的，以第一路由表为表2所示为例。由表2可知，该第一路由表中包括：NFC应用的相关信息与承载该NFC应用的SE的SE标识的对应关系。其中，NFC应用的相关信息中，AID是该NFC应用的标识，其在同一个SE中唯一存在。例如，在同一个SE中，一个AID可以用来唯一标识一个公交卡应用、银行卡应用、身份证应用或社保健康卡应用。另外，在不同的SE中承载的NFC应用的AID可以相同，也可以不同。在本实施例中，还可用其他的方式来标识NFC应用。对于不同的NFC应用，访问其的交易指令遵循的协议和规则可以相同，也可以不同。访问NFC应用的交易指令遵循的协议和规则可以在安装时确定，在使用过程中也可以动态改变。例如，访问公交卡应用、门禁卡应用、银行卡应用的交易指令都有其各自遵循的协议和规则。访问NFC应用的交易指令遵循的协议和规则可以包括用户自定义的协议和规则。访问NFC应用的交易指令使用的NFC物理技术有：TYPEA技术，TYPEB技术，TYPEF技术等。对于不同的NFC应用，访问其的交易指令使用的NFC物理技术可以相同，也可以不同。访问NFC应用的交易指令使用的NFC物理技术可以在安装时确定。例如，访问身份证应用的交易指令使用的是TYPEB技术。访问公交卡应用的交易指令使用的是TYPEA技术。访问NFC应用的交易指令，可以是一个字符串。该字符串可以是固定不变的，也可以是动态变化的。该字符串可以是一个字节或几个比特位。访问不同NFC应用的字符串可以相同，也可以不同。访问NFC应用的字符串可以在安装时确定，在使用过程中也可以动态改变。运行NFC应用时，对终端的功耗状态的要求可以包括：感应充电、有电、无电、亮屏、灭屏等。运行不同NFC应用时，对终端的功耗状态的要求可以是相同的，也可以是不同的。例如，运行银行卡应用时，要求终端的功耗状态为亮屏。运行门禁卡应用时，要求终端的功耗状态是灭屏。运行NFC应用时，对终端的功耗状态可以包括预定义的功耗状态，如有电、无电等。还可以包括用户自定义的一些状态，如终端的电量等。如定义运行某NFC应用时，终端的电量 要求大于50％。
表2
Figure PCTCN2019112689-appb-000001
在下载NFC应用时，该NFC应用对应在表2所示的第一路由表中的路由信息可以根据终端的DH下发的路由配置命令来配置。在第一路由表中，实际配置的NFC应用对应的路由信息中可以包括NFC应用的相关信息中的至少一种。也就是说，实际配置的NFC应用对应的路由信息中可以包括以下信息中的至少一种：NFC应用的AID、访问NFC应用的交易指令遵循的协议和规则、访问NFC应用的交易指令使用的NFC物理技术、访问NFC应用的交易指令以及运行NFC应用时对终端的功耗状态的要求。
例如，在下载某NFC应用时，该NFC应用下载到了终端的某个SE中。终端的该SE在确定出该NFC应用下载到该SE成功后，可以向终端的DH发送用于指示该NFC应用已下载成功的消息。终端的DH接收到该消息后，可以向终端的NFCC发送路由配置命令。该路由配置命令可以是在终端的本地预先定义的，也可以是提供该NFC应用下载资源的服务器下发给终端的DH的。该路由配置命令用于指示NFCC在上述第一路由表中配置与该NFC应用对应的路由信息。该路由配置命令中可以包括：在第一路由表中配置路由信息时需要配置的信息，以及需要配置的信息的具体取值。该路由配置命令中还包括：承载该NFC应用的SE的SE标识。终端的NFCC根据该路由配置命令，便可以在上述第一路由表中配置该NFC应用对应的路由信息。该路由信息中可以包括，该NFC应用的相关信息与SE标识的对应关系。
由于不同SE中承载的NFC应用的AID可能不同，访问不同NFC应用的交易指令遵循的协议和规则可能不同，使用的NFC物理技术可能不同，交易指令可能不同，运行NFC应用时终端的功耗状态可能不同。因此，终端的NFCC在接收到交易指令后，可以根据表2所示的第一路由表来确定该交易指令所访问的NFC应用承载在终端的哪个SE中，即确定目标SE。示例性的，终端的NFCC可以根据第一路由表和交易指令，从第一路由表中确定一路由信息(如本申请中的第一路由信息可以为该路由信息)。该路由信息可以是第一路由表中满足匹配条件(本申请中的第一匹配条件可以为该匹配条件)的路由信息。该匹配条件可以包括以下至少一种：条件a：路由信息中的AID与交易指令中携带的应用标识符AID相同，条件b：路由信息中的协议和规则与交易指令遵循的协议和规则相同，条件c：路由信息中的NFC物理技术与交易指令使用的NFC物理技术相同，条件d：路由信息中的交易指令与接收到的交易指令相同。在一些实施例中，终端的NFCC可以按照上述四个条件的预设顺序(本申请中的第一预设顺序可以为该预设顺序)将第一路由表中满足该预设顺序中首个条件的路由信息作为确定的路由信息。
另外，在确定目标SE时，运行NFC应用时对终端的功耗状态的要求这一信息可 以作为辅助条件来使用，这样，可以提高自动激活NFC应用的安全性。
例如，如图5所示，以上述预设顺序为条件a，条件b，条件c，条件d为例。终端的NFCC根据第一路由表确定交易指令所访问的NFC应用承载在终端的哪个SE中的具体实现可以包括：
终端的NFCC在接收到交易指令后，可以判断该交易指令中是否包含AID。如果确定出该交易指令中包括AID，则可以按照第一路由表中各条路由信息的配置顺序或者按照终端中包括的SE的优先级顺序(SE的优先级可以是预定义的，也可以是用户设置的)，遍历查找第一路由表中的路由信息，以确定第一路由表中是否存在AID与接收到的交易指令中的AID相同的路由信息。如果存在AID与该交易指令中的AID相同的路由信息，且该条路由信息中包括的运行NFC应用时对终端的功耗状态的要求这一信息的取值与终端当前的功耗状态相同，则该条路由信息中包括的SE标识所标识的SE即为目标SE。
如果接收到交易指令中不包含AID，或者，第一路由表中不存在AID与接收到的交易指令中的AID相同的路由信息，或者，第一路由表中存在AID与接收到的交易指令中的AID相同的路由信息，但该条路由信息中包括的运行NFC应用时对终端的功耗状态的要求这一信息的取值与终端当前的功耗状态不同，则终端的NFCC可以按照第一路由表中各条路由信息的配置顺序或者按照终端中包括的SE的优先级顺序，遍历查找第一路由表中的路由信息，以确定第一路由表中是否存在协议和规则与接收到的交易指令所遵循的协议和规则相同的路由信息。如果存在，且该条路由信息中包括的运行NFC应用时对终端的功耗状态的要求这一信息的取值与终端当前的功耗状态相同，则该条路由信息中包括的SE标识所标识的SE即为目标SE。
如果第一路由表中不存在协议和规则与接收到的交易指令所遵循的协议和规则相同的路由信息，或者，第一路由表中存在协议和规则与接收到的交易指令所遵循的协议和规则相同的路由信息，但该条路由信息中包括的运行NFC应用时对终端的功耗状态的要求这一信息的取值与终端当前的功耗状态不同，则终端的NFCC可以按照第一路由表中各条路由信息的配置顺序或者按照终端中包括的SE的优先级顺序，遍历查找第一路由表中的路由信息，以确定第一路由表中是否存在NFC物理技术与接收到的交易指令使用的NFC物理技术相同的路由信息。如果存在，且该条路由信息中包括的运行NFC应用时对终端的功耗状态的要求这一信息的取值与终端当前的功耗状态相同，则该条路由信息中包括的SE标识所标识的SE即为目标SE。
如果第一路由表中不存在NFC物理技术与接收到的交易指令所使用的NFC物理技术相同的路由信息，或者，第一路由表中存在NFC物理技术与接收到的交易指令所使用的NFC物理技术相同的路由信息，但该条路由信息中包括的运行NFC应用时对终端的功耗状态的要求这一信息的取值与终端当前的功耗状态不同，则终端的NFCC可以按照第一路由表中各条路由信息的配置顺序或者按照终端中包括的SE的优先级顺序，遍历查找第一路由表中的路由信息，以确定第一路由表中是否存在交易指令与接收到的交易指令相同的路由信息。如果存在，且该条路由信息中包括的运行NFC应用时对终端的功耗状态的要求这一信息的取值与终端当前的功耗状态相同，则该条路由信息中包括的SE标识所标识的SE即为目标SE。
如果第一路由表中不存在交易指令与接收到的交易指令相同的路由信息，或者，第一路由表中存在交易指令与接收到的交易指令相同的路由信息，但该条路由信息中包括的运行NFC应用时对终端的功耗状态的要求这一信息的取值与终端当前的功耗状态不同，则终端的NFCC可以将优先级最高的SE作为目标SE。
在一些实施例中，上述表2中NFC应用的相关信息中“访问NFC应用的交易指令”这一信息可以替换为“访问NFC应用的交易指令对应的掩码”。其中，访问NFC应用的交易指令对应的掩码，可以是交易指令对应的固定字符串包括的部分字符比特。访问不同NFC应用的字符串对应的掩码可以相同，也可以不同。因此，可以通过接收到的交易指令对应的掩码来判断交易指令所访问的NFC应用承载于终端的哪个SE中。
在终端确定出接收到的交易指令所访问的NFC应用承载在终端的哪个SE中，即确定出目标SE之后，可以根据该目标SE的第二路由表，从目标SE承载的至少一个NFC应用中确定交易指令所访问的NFC应用，即确定目标NFC应用。
示例性的，以第二路由表为表3为例。由表3可知，该第二路由表中包括：NFC应用的相关信息与NFC应用的句柄(handle)的对应关系。其中，NFC应用的相关信息中，NFC应用的AID、访问NFC应用的交易指令、访问NFC应用的交易指令对应的掩码、访问NFC应用的交易指令遵循的协议和规则以及访问NFC应用的交易指令使用的NFC物理技术的相关描述，可以参考表2所示的第一路由表中对应信息的具体描述，此处不再赘述。另外，对于固定优先级，可以是终端根据NFC应用的下载顺序自动设置的，也可以是用户在下载NFC应用时手动设置的。对于可变优先级，初始设置可以为空值(null)。之后终端可以根据用户使用NFC应用的习惯以及当前的场景信息动态调整。如用户在某个时间、某个地理位置经常使用某NFC应用，则在当前时间和当前地理位置与其相同时，终端可以将该NFC应用的可变优先级设置为最高。NFC应用的句柄可以在SE中唯一确定NFC应用。
表3
Figure PCTCN2019112689-appb-000002
在下载NFC应用时，该NFC应用对应在表3所示的第二路由表中的路由信息可以根据终端的DH下发的安装命令以及实际情况(固定优先级和可变优先级是根据场景触发或用户设置来配置的)来配置。在第二路由表中，实际配置的NFC应用对应的路由信息中可以包括：NFC应用的AID、访问NFC应用的交易指令、访问NFC应用的交易指令对应的掩码、NFC应用的固定优先级、NFC应用的可变优先级、访问NFC应用的交易指令遵循的协议和规则以及访问NFC应用的交易指令使用的NFC物理技 术中的至少一种。
例如，终端的DH接收到用于指示NFC应用已下载成功的消息后，还可以向承载该NFC应用的SE发送安装命令。该安装命令可以是招商银行的服务器下发给终端的DH的。该安装命令用于指示该SE在上述第二路由表中配置与该NFC应用对应的路由信息。该安装命令中可以包括：在第二路由表中配置路由信息时需要配置的信息，以及需要配置的信息的具体取值。该安装命令中还包括：该NFC应用的句柄。承载该NFC应用的SE根据该安装命令，便可以在上述第二路由表中配置该NFC应用对应的路由信息。该路由信息中可以包括，该NFC应用的相关信息与NFC应用的句柄的对应关系。
由于同一个SE中承载的NFC应用的标识不同，访问不同NFC应用的交易指令可能不同，交易指令对应的掩码可能不同、可变优先级不同，因此终端的SE在接收到交易指令后，可以根据该第二路由表来确定该交易指令所访问的NFC应用是该SE中的哪个NFC应用。从而自动激活对应的NFC应用，并执行交易指令以完成交易。示例性的，终端的SE可以根据第二路由表和交易指令，从第二路由表中确定一路由信息(如本申请中的第二路由信息可以为该路由信息)。该路由信息可以是第二路由表中满足匹配条件(本申请中的第二匹配条件可以为该匹配条件)的路由信息。该匹配条件可以包括以下至少一种：条件e：路由信息中的AID与交易指令中携带的AID相同，条件f：路由信息中的交易指令与接收到的交易指令相同，条件g：路由信息中的掩码与接收到的交易指令对应的掩码相同，条件h：路由信息中包括的可变优先级为第一优先级，该第一优先级为第二路由表的路由信息中可变优先级最高的优先级。在一些实施例中，终端的SE可以按照上述四个条件的预设顺序(本申请中的第二预设顺序可以为该预设顺序)将第二路由表中满足该预设顺序中首个条件的路由信息作为确定的路由信息。
另外，在确定目标NFC应用时，访问NFC应用的交易指令遵循的协议和规则以及使用的NFC物理技术这两信息中的一个或两个，可以作为辅助条件来使用，这样，可以提高自动激活NFC应用的安全性。
例如，以将访问NFC应用的交易指令遵循的协议和规则以及使用的NFC物理技术这两个信息作为辅助条件来确定目标NFC应用，预设顺序为条件e，条件f，条件g，条件h为例，如图6所示，终端的SE根据该SE的第二路由表，从该SE承载的至少一个NFC应用中确定交易指令所访问的NFC应用，即确定目标NFC应用的具体实现可以包括：
终端的SE接收到交易指令后，可以判断该交易指令中是否包含AID。如果该交易指令中包含AID，则该SE可以遍历查找第二路由表中的路由信息，以确定第二路由表中是否存在AID与该交易指令中的AID相同的路由信息。如果第二路由表中存在AID与该交易指令中的AID相同的路由信息，该SE可以判断该条路由信息中包括的访问NFC应用的交易指令遵循的协议和规则以及使用的NFC物理技术这两个信息的取值与当前接收到的交易指令遵循的协议和规则以及使用的NFC物理技术是否相同。如果该条路由信息中包括的协议和规则以及使用的NFC物理技术与当前接收到的交易指令遵循的协议和规则以及使用的NFC物理技术相同，则该条路由信息中包括的 NFC应用的句柄对应的NFC应用即为目标NFC应用。
如果上述交易指令中不包含AID，或者，第二路由表中不存在AID与接收到的交易指令中的AID相同的路由信息，或者第二路由表中存在AID与接收到的交易指令中的AID相同的路由信息，但该条路由信息中包括的协议和规则或使用的NFC物理技术与当前接收到的交易指令遵循的协议和规则以及使用的NFC物理技术不同，则终端的SE可以遍历查找第二路由表中的路由信息，以确定第二路由表中是否存在交易指令与接收到的交易指令相同的路由信息。如果第二路由表中存在交易指令与接收到的交易指令相同的路由信息，该SE可以判断该条路由信息中包括的访问NFC应用的交易指令遵循的协议和规则以及使用的NFC物理技术这两个信息的取值与当前接收到的交易指令遵循的协议和规则以及使用的NFC物理技术是否相同。如果该条路由信息中包括的协议和规则以及使用的NFC物理技术与当前接收到的交易指令遵循的协议和规则以及使用的NFC物理技术相同，则该条路由信息中包括的NFC应用的句柄对应的NFC应用即为目标NFC应用。
如果第二路由表中不存在交易指令与接收到的交易指令相同的路由信息，或者第二路由表中存在交易指令与接收到的交易指令相同的路由信息，但该条路由信息中包括的协议和规则或使用的NFC物理技术与当前接收到的交易指令遵循的协议和规则以及使用的NFC物理技术不同，则终端的SE可以遍历查找第二路由表中的路由信息，以确定第二路由表中是否存在掩码与接收到的交易指令对应的掩码相同的路由信息。如果第二路由表中存在掩码与接收到的交易指令对应的掩码相同的路由信息，该SE可以判断该条路由信息中包括的访问NFC应用的交易指令遵循的协议和规则以及使用的NFC物理技术这两个信息的取值与当前接收到的交易指令遵循的协议和规则以及使用的NFC物理技术是否相同。如果该条路由信息中包括的协议和规则以及使用的NFC物理技术与当前接收到的交易指令遵循的协议和规则以及使用的NFC物理技术相同，则该条路由信息中包括的NFC应用的句柄对应的NFC应用即为目标NFC应用。
如果第二路由表中不存在掩码与接收到的交易指令对应的掩码相同的路由信息，或者第二路由表中存在掩码与接收到的交易指令对应的掩码相同的路由信息，但该条路由信息中包括的协议和规则或使用的NFC物理技术与当前接收到的交易指令遵循的协议和规则以及使用的NFC物理技术不同，则终端的SE可以将第二路由表中，可变优先级最高的路由信息中包括的NFC应用的句柄对应的NFC应用即为目标NFC应用。
如果第二路由表中没有可变优先级这一信息，也就是说，经过上述匹配，未能确定出目标NFC应用，则终端的SE可以将默认的NFC应用作为目标NFC应用。该默认的NFC应用可以是用户设置的，也可以是预定义的。
在一些实施例中，终端的SE可以结合第二路由表中的固定优先级这一信息，按照优先级从高到低的顺序遍历查找第二路由表。在其他一些实施例中，终端的SE也可以结合第二路由表中的可变优先级这一信息，按照优先级从高到低的顺序查找遍历查找第二路由表。在另外一些实施例中，终端的SE也可以同时结合第二路由表中的固定优先级和可变优先级，遍历查找第二路由表。这样，可以提高匹配效率，能快速的确定出接收到的交易指令所访问的NFC应用。
这样，终端在确定出目标NFC应用后，便可在目标SE中运行该目标NFC应用，并执行接收到的交易指令，以完成交易。
为了便于理解，以下结合具体示例，对目标SE和目标NFC应用的确定过程进行举例介绍。例如，结合图1所示，终端有三个SE，分别为以SIM卡形式存在的SE 1，与NFC芯片一起封装的SE 2，以及以终端的AP形式存在的inSE，如称为SE 3。
终端中下载了多个NFC应用，这些NFC应用可以承载在终端的三个SE中。如，终端中下载了招商银行的银行卡应用701、车钥匙应用702、社保健康卡应用703、门禁卡应用704。其中，如图7所示，招商银行的银行卡应用701和门禁卡应用704承载在SE 1中。车钥匙应用702承载在SE 2中。社保健康卡应用703承载在SE 3中。在下载招商银行的银行卡应用701、车钥匙应用702、社保健康卡应用703、门禁卡应用704时，终端在第一路由表和第二路由表中分别配置每个NFC应用的路由信息。配置对应路由信息后的第一路由表可以参见表4所示。配置对应路由信息后的SE 1中的第二路由表如表5。配置对应路由信息后的SE 2中的第二路由表如表6所示。配置对应路由信息后的SE 3中的第二路由表如表7所示。

其中，在表7所示的SE 3中的第二路由表中，第一条路由信息为社保健康卡应用703对应的路由信息。
以配置招商银行的银行卡应用701的路由信息为例，对在第一路由表和第二路由 表中进行路由配置的过程进行介绍。对于门禁卡应用704、车钥匙应用702以及社保健康卡应用703对应路由信息配置过程的具体描述与招商银行的银行卡应用701对应的路由信息配置过程的具体描述类似。
例如，用户想要终端能够模式招商银行的银行卡应用701。根据用户的操作，终端可以下载该招商银行的银行卡应用701到终端的SE中。如该银行卡应用701下载到了SE 1中。在该银行卡应用701下载到SE 1成功后，该SE 1可以向终端的DH发送指示成功的消息。终端的DH响应于该消息，可以向终端的NFCC发送路由配置命令。如该路由配置命令中包括：在第一路由表中配置路由信息时需要配置的信息：招商银行的银行卡应用701的AID、访问该银行卡应用701的交易指令遵循的协议和规则以及运行NFC应用时对终端的功耗状态的要求。且需要配置的这三个信息的具体取值依次为：AID 1，协议和规则1和亮屏。该路由配置命令中还包括承载该招商银行的银行卡应用701的SE的SE标识，如SE 1。
终端的NFCC根据DH下发的路由配置命令便可以进行路由配置，即在第一路由表中配置招商银行的银行卡应用701对应的路由信息。如，配置的路由信息如表4所示的第一路由表中的第一条路由信息所示。终端的NFCC可以将其他不需要配置的信息设置为空值(null)。
终端的DH响应于接收到的消息，还可以向终端的SE 1发送安装命令。该安装命令是招商银行的服务器下发给终端的DH的。如，该安装命令中包括：在第二路由表中配置路由信息时需要配置的信息：招商银行的银行卡应用701的AID、访问该银行卡应用701的交易指令遵循的协议和规则以及访问该银行卡应用701的交易指令使用的NFC物理技术。且需要配置的这三个信息的具体取值依次为：AID 1，协议和规则1和NFC物理技术1。该安装命令中还包括该银行卡应用701的句柄，如句柄1。
终端的SE 1根据DH下发的安装命令便可以进行路由配置，即在SE 1中的第二路由表中配置招商银行的银行卡应用701对应的路由信息。配置的路由信息如表5中的第一条路由信息所示。其中，银行卡应用701的固定优先级是根据下载顺序设置的，如设置为1(数值越大固定优先级越低)。可变优先级为空值(null)，其他不需要配置的信息也设置为空值。
这样，招商银行的银行卡应用701对应的路由信息便配置完成，后续可利用该路由信息确定出交易指令是否要访问该NFC应用。
例如，用户在超市购物结束需要付款时，可以用终端靠近收银台的POS机具。终端的NFCC可以接收到POS机具发送的交易指令，该交易指令中携带AID 1。终端的NFCC可以判断接收到的交易指令中是否包含AID。在确定该交易指令中包括AID时，终端的NFCC可以按照SE的优先级顺序，遍历查找表4所示的第一路由表中的路由信息，以确定表4所示的第一路由表中是否存在AID与AID 1相同的路由信息。由表4可知，表4所示的第一路由表中第一条路由信息的AID与该AID 1相同。终端的NFCC可以获取终端当前的功耗状态，如获取到的当前的功耗状态为亮屏，其与该条路由信息中包括的运行NFC应用时对终端的功耗状态的要求这一信息的取值“亮屏”相同。那么终端的NFCC根据该第一条路由信息，可以确定SE 1即为目标SE。在确定出SE 1为目标SE之后，终端的NFCC可以将交易指令发送至该SE 1。
SE 1接收到交易指令后，可以根据该交易指令确定该SE 1中的哪个NFC应用是交易指令所访问的NFC应用。如，SE 1接收到交易指令后，可以判断该交易指令中是否包含AID。在确定该交易指令中包含AID时，该SE 1可以按照固定优先级的顺序，遍历查找表5所示的第二路由表中的路由信息，以确定第二路由表中是否存在AID与AID 1相同的路由信息。由表5可知，表5所示的第一路由表中第一条路由信息的AID与该AID 1相同。该SE 1可以判断接收到的交易指令所遵循的协议和规则以及使用的NFC物理技术是否为协议和规则1以及NFC物理技术1。如果是，则该SE 1可以确定该条路由信息中句柄1对应的NFC应用即为目标NFC应用，即SE 1中承载的招商银行的银行卡应用701为交易指令所访问的NFC应用。SE 1可以运行该银行卡应用701，并执行交易指令，以完成扣款。
又例如，用户想要驾车回家，可以用终端靠近汽车的车门。终端的NFCC可以接收到车门上的读卡器发送的交易指令，该交易指令中未携带AID。终端的NFCC可以判断接收到的交易指令中是否包含AID。在确定该交易指令中未包括AID时，终端的NFCC可以按照SE的优先级顺序，遍历查找表4所示的第一路由表中的路由信息，以确定表4所示的第一路由表中是否存在协议和规则与接收到的交易指令遵循的协议和规则相同的路由信息。如接收到的交易指令所遵循的协议和规则为协议和规则2，由表4可知，终端的NFCC按照SE的优先级顺序，查找第一条路由信息确定其包含的协议和规则这一信息的取值与协议和规则2不相同，再查找第四条路由信息确定其包含的协议和规则这一信息的取值与协议和规则2也不相同，然后查找第二条路由信息确定其包含的协议和规则这一信息的取值与协议和规则2相同。终端的NFCC可以获取终端当前的功耗状态，如获取到的当前的功耗状态为有电，其与该条路由信息中包括的运行NFC应用时对终端的功耗状态的要求这一信息的取值“有电”相同。那么终端的NFCC根据该第二条路由信息，可以确定SE 2即为目标SE。在确定出SE 2为目标SE之后，终端的NFCC可以将交易指令发送至该SE 2。
SE 2接收到交易指令后，可以根据该交易指令确定该SE 2中的哪个NFC应用是交易指令所访问的NFC应用。如，SE 2接收到交易指令后，可以判断该交易指令中是否包含AID。在确定该交易指令中不包含AID时，该SE 2可以遍历查找表6所示的第二路由表中的路由信息，以确定第二路由表中是否存在交易指令与接收到的交易指令相同的路由信息。如果未查找到交易指令与接收到的交易指令相同的路由信息，则根据表6查找是否存在掩码与接收到的交易指令对应的掩码相同的路由信息。例如，接收到的交易指令对应的掩码为掩码2。那么，SE 2可以判断接收到的交易指令所遵循的协议和规则以及使用的NFC物理技术是否为协议和规则2以及NFC物理技术2。如果是，则该SE 2可以确定该条路由信息中句柄2对应的NFC应用即为目标NFC应用，即SE 2中承载的车钥匙应用702为交易指令所访问的NFC应用。SE 2可以运行该车钥匙应用702，并执行交易指令，以便打开车门。
再例如，用户驾车回到家，想要打开房门时，可以用终端靠近房间门的门锁。终端的NFCC可以接收到门锁发送的交易指令，该交易指令中未携带AID。终端的NFCC可以判断接收到的交易指令中是否包含AID。在确定该交易指令中未包括AID时，终端的NFCC可以按照SE的优先级顺序，遍历查找表4所示的第一路由表中的路由信 息，以确定表4所示的第一路由表中是否存在协议和规则与接收到的交易指令所遵循的协议和规则相同的路由信息。如，接收到的交易指令所遵循的协议和规则为协议和规则4，由表4可知，第一路由表中不存在协议和规则与接收到的交易指令所遵循的协议和规则4相同的路由信息。终端的NFCC可以按照SE的优先级顺序，遍历查找表4所示的第一路由表中的路由信息，以确定表4所示的第一路由表中是否存在NFC物理技术与接收到的交易指令所使用的NFC物理技术相同的路由信息。如，接收到的交易指令所使用的NFC物理技术为NFC物理技术4，由表4可知，第一路由表中不存在NFC物理技术与接收到的交易指令所使用的NFC物理技术4相同的路由信息。终端的NFCC可以按照SE的优先级顺序，遍历查找表4所示的第一路由表中的路由信息，以确定表4所示的第一路由表中是否存在交易指令与接收到的交易指令相同的路由信息。如接收到的交易指令为交易指令4。由表4可知，表4所示的第一路由表中第四条路由信息的交易指令与该交易指令4相同。终端的NFCC可以获取终端当前的功耗状态，如获取到的当前的功耗状态为灭屏，其与该条路由信息中包括的运行NFC应用时对终端的功耗状态的要求这一信息的取值“灭屏”相同。那么终端的NFCC根据该第四条路由信息，可以确定SE 1即为目标SE。在确定出SE 1为目标SE之后，终端的NFCC可以将交易指令发送至该SE 1。
SE 1接收到交易指令后，可以根据该交易指令确定该SE 1中的哪个NFC应用是交易指令所访问的NFC应用。如，SE 1接收到交易指令后，可以判断该交易指令中是否包含AID。在确定该交易指令中不包含AID时，该SE 1可以按照固定优先级的顺序，遍历查找表5所示的第二路由表中的路由信息，以确定第二路由表中是否存在交易指令与交易指令4相同的路由信息。由表5可知，表5所示的第一路由表中第二条路由信息的交易指令与该交易指令4相同。该SE 1可以判断接收到的交易指令所遵循的协议和规则以及使用的NFC物理技术是否为协议和规则4以及NFC物理技术4。如果是，则该SE 1可以确定该条路由信息中句柄4对应的NFC应用即为目标NFC应用，即SE 1中承载的门禁卡应用704为交易指令所访问的NFC应用。SE 1可以运行该门禁卡应用704，并执行交易指令，以便打开房门。
由上可以看到的是，用户从付款，到开车门，到开房门，只需将终端靠近对应的读卡器或POS机具，终端便可识别到对应的NFC应用并自动激活，以完成交易。无需用户手动切换，提高了终端与用户的交互效率，提高了终端的智能性。极大的提高了用户的使用体验。
在一些实施例中，为了访问终端自动激活的NFC应用不是用户想要使用的，在终端确定出目标NFC应用后，可以在终端的显示屏上显示提示信息，提示用户将要激活目标NFC应用，以完成交易。例如，如图8所示，以上述在用户在超市购物结束需要付款时，终端确定出目标NFC应用为招商银行的银行卡应用701为例。在终端确定出目标NFC应用为招商银行的银行卡应用701后，可以显示提示窗口，该提示窗口中包括提示信息801，该提示信息801可以提示用户将要激活招商银行的银行卡应用701完成付款。终端还可以在提示窗口中显示取消按钮802。当用户不想要使用招商银行的银行卡应用701付款时，可以对该取消按钮802执行点击操作。终端响应于该点击操作，可以不执行激活该招商银行的银行卡应用701的操作。终端还可以在提示窗口 中显示倒计时读秒803，以提示用户在倒计时读秒结束时(如3秒后)，将激活招商银行的银行卡应用701，提示窗口也将自动关闭。
在本申请另外一些实施例中，在终端有多个SE(如三个SE，三个SE的SE标识分别为SE 1，SE 2以及SE 3)的场景下，终端可以存储有SE与该SE中承载的NFC应用的对应关系。例如，如表8所示，终端存储有SE标识与该SE中承载的NFC应用的对应关系。其中，标识为SE 1的SE中承载了NFC应用1、NFC应用3以及NFC应用6。标识为SE 2的SE中承载了NFC应用4以及NFC应用5。标识为SE 3的SE中承载了NFC应用2以及NFC应用7。
表8

在用户将终端靠近POS机具或读卡器时，可以接收到交易指令，该交易指令中可以携带交易指令所要访问NFC应用所在的SE的SE标识。这样，终端便可以根据交易指令中携带的SE标识和表8，确定交易指令所访问的NFC所承载的SE，即确定目标SE。如果该目标SE未激活，终端可以激活该目标SE。然后，可以从目标SE中确定出交易指令所要访问的NFC应用，即目标NFC应用，并自动将其激活。其中，从目标SE中确定目标NFC应用的具体实现可以参考本申请其他实施例中对应内容的具体描述，此处不再详细赘述。
如图9所示，本申请另一实施例提供一种NFC芯片***。该NFC芯片***可以包括NFC芯片901和至少两个SE 902(如图9中以包括三个SE为例示出)。其中，NFC芯片901和至少两个SE 902中的目标SE可以用于执行上述任一实施例所提供的NFC应用的自动激活方法。目标SE可以为上述至少两个SE中的任意一个。
