目前NFC还并没有完全的融入到我们的日常生活 里，以致于很多朋友除了数据传输外，并不清楚手机NFC技术具体还能够做哪些事情？所以我们今天除了介绍其基本功能外，还会通过实际的操作让大家来了解NFC技术,感兴趣的朋友可以了解下，希望本文可以帮助到你
早在2010年末，NFC这个名词就开始被人们广泛的关注，当时谷歌在其官方博客上发布了与三星合作研发的第二款谷歌手机Nexus S，三星的型号为i9020，虽然这款手机搭载了当时最新的Android 2.3版系统，但NFC应用技术仍然抢夺了大部分的关注目光，众多手机终端厂商也纷纷表示要在自己的新一代产品中加入NFC模块。
虽然对该技术很熟悉，但因为一些业界内存在的分歧，导致手机NFC技术不能够被很好的推广应用，所以目前还并没有完全的融入到我们的日常生活 里，以致于很多朋友除了数据传输外，并不清楚手机NFC技术具体还能够做哪些事情？所以我们今天除了介绍其基本功能外，还会通过实际的操作让大家来了解 NFC技术。
公交卡实战NFC功能
对于当前来说，NFC功能在我们的实际生活中还并没有完全的展现出来，除了能够近距离传输文件外，也可对应多种支持NFC的APP来进行其他功 能，比如查询公交一卡通的消费记录等。而另一个比较实用的NFC功能，则是使用NFC标签来指定智能手机转换至特定的模式，比如在公司开会时，只需要轻轻 的将NFC标签碰触手机，就可以将手机转换为静音模式，非常方便。

事实上，很多NFC的功能都是需要特定的&标签&来操作的，而NFC标签可以自制也可以在淘宝进行购买。不过近日我们发现，只需要一款能够对 NFC标签读取的APP应用，就可以让生活中带有NFC芯片的产品变成NFC标签，比如北京市政公交一卡通，省去了另外购买NFC标签的金钱。下面我们就 一起来了解如何通过公交一卡通，来对手机指定一些操作。
HTC One X与市政公交一卡通
准备工具：
带有NFC模块的手机一部
北京市政公交一卡通
能够对NFC标签读取的APP应用
其实除了北京市政公交一卡通外，地铁单程票卡也可以作为NFC标签，再加上我们使用的HTC One X是一部支持NFC模块的手机，所以有了这些准备工具，就可以去下载一款能够对NFC标签读取的APP应用，目前类似的应用较多，而我们使用的应用名称为 NFC Tag。
NFC Tag介绍
通过NFC Tag扫描公交一卡通
配对成功后，就能够自行设置&标签名称&以及&任务信息&
NFC Tag所支持的功能十分齐全，当我们开启NFC Tag时，点击&扫描&后，就可以将公交一卡通贴到手机上进行配对，而配对成功后，就能够自行设置&标签名称&以及&任务信息&，来确定当手机接触NFC 标签后会转换哪些模式。包括开启/关闭无线、静音模式、选择铃声、屏幕亮度、发送短信、直接启动某些APP应用等。设置成功后关闭NFC Tag，当手机再次与NFC标签接触时，就会自动开启早前已经设定好的模式了。
设置当手机接触NFC标签后可以转换的模式
模式设定完成，当手机碰触NFC标签后，手机自动转换成静音模式
而且NFC Tag能够一次性支出多个NFC标签，能够在不同的环境中应对不同的事件，比如在车中贴上一个NFC标签，当我们上车时，手机就会自动开启导航；在会议室 桌上贴上NFC标签，开会时就会自动转为静音模式；在家中贴上NFC标签，当孩子回家&刷卡&后，就会自动发短信给父母以告知；在相框后边贴上NFC标 签，当手机碰触相框时就会自动拨打相框中人物的电话等等。而这里也仅仅是一些基础的想法而已，大家还可以创新的想出更多的玩法。
编后语：现在你是否想用NFC了呢，不要急，很快NFC将进入我们的生活当中。
