NFC是一种流行的技术，已经使用了几年多。它无处不在，从便携式扬声器到支付系统，适用于各种各样的事情，从传输联系人或文件到将智能手机与汽车配对。可能性很多，有关 iPhone 的NFC功能的问题也很多。如果您想找到诸如“我的 iPhone NFC是否启用？”、“如何(How)在我的 iPhone 上打开NFC ？”等问题的简单答案。(NFC)或“我的 iPhone 12 上有NFC吗？” (NFC)继续阅读：
注意：(NOTE:)如果您不知道NFC是什么以及为什么它如此受欢迎，我们建议您先阅读这篇文章：什么是 NFC，它有什么作用？(What is NFC and what does it do?).
如何在 iPhone 上开启 NFC
我们要直截了当地开始：你不能在 iPhone 上打开或关闭NFC ！这是为什么？答案比您想象的要简单：iPhone 的NFC功能由需要它的应用程序启用或禁用。因此，与Android 上(NFC on Android)的 NFC 不同，直接从操作系统打开或关闭它非常简单，而在 iOS 中，NFC没有主开关。
与 Android 相比，iPhone 上的NFC(NFC)实现方式不同
(Does)我的 iPhone 有 NFC 吗？哪些 iPhone 支持 NFC？
近年来发布的所有 iPhone 都有NFC。事实上，自 2014 年推出的 iPhone 6 以来，每款 iPhone 都内置了NFC芯片。如果您需要详细信息来确定，以下是支持NFC的 iPhone 的完整列表：
- iPhone 13、iPhone 13迷你(Mini)、iPhone 13专业版(Pro)、iPhone 13专业版 Max(Pro Max)
- iPhone 12、iPhone 12迷你(Mini)、iPhone 12专业版(Pro)、iPhone 12专业版 Max(Pro Max)
- iPhone 11、iPhone 11 Pro、iPhone 11 Pro Max、iPhone SE（第二代(Gen)）
- iPhone XS 和 iPhone XS Max
- iPhone XR
- iPhone X
- iPhone 8、iPhone 8 加号
- iPhone 7、iPhone 7 加号
- iPhone 6、iPhone 6 Plus、iPhone 6S、iPhone 6S Plus、iPhone SE
iPhone 13 内置 NFC
提示：(TIP: )如果您不确定自己的型号，请阅读我们的指南以了解您拥有的 iPhone(our guide to find out what iPhone you have)。
具有NFC(NFC)的第一代 iPhone（iPhone 6 型号）将此功能限制为仅通过Apple Pay 支付(Apple Pay)。但是，iPhone 7 和更新的型号也允许使用NFC来读取NFC标签，使用 3rd 方应用程序。
此外，从 iOS 13 和 iPhone XS 和 XR 的发布开始，iPhone 还可以使用第三方NFC应用程序（例如iPhone(NFC for iPhone)的 NFC或NXP 的 NFC TagWriter）对空白(NFC TagWriter by NXP)NFC标签进行编码。
最后，从 iPhone XS 开始，一直到 iPhone 12 和 iPhone 13，这些智能手机还能够在后台读取NFC标签。换句话说，您不再需要安装 3rd 方应用程序并手动读取NFC标签：只需将您的 iPhone 轻触NFC标签，它就会自动识别它。
为了让您更轻松地检查您的 iPhone 是否有NFC并了解您可以使用它，我们制作了下表：
iPhone NFC兼容性和功能
顺便说一句，所有具有NFC且使用 iOS 14 或更高版本的 iPhone 都可以自动读取各种NFC标签，而无需第三方应用程序，包括但不限于网址 ( URL(URLs) )、电子邮件、电话号码和短信(SMS)。
如何在 iPhone 上使用 NFC
你现在知道你的 iPhone 是否有NFC。但是你如何使用 iPhone 的NFC呢？答案很简单：您所要做的就是将您的 iPhone 轻触到另一台支持NFC的设备上。或者只需将 iPhone 的顶部背面靠近NFC标签。然后，iPhone 读取NFC标签并在其屏幕上显示通知。
如何在 iPhone 上使用NFC：NFC通知
阅读 iPhone 上的NFC通知内容，如果您想了解它，请点击它以执行其操作。例如，如果您将 iPhone 轻触支持NFC的便携式扬声器，您将收到通知以配对两个设备。如果这样做，您将能够将声音从 iPhone 输出到扬声器。通过NFC(NFC)进行整个配对比手动搜索可用的蓝牙(Bluetooth)设备并连接到扬声器要快得多。iPhone 上NFC的简洁用例，对吧？
如何使用 iPhone 的NFC进行支付
我们可以为您提供的最佳示例是 Apple Pay，因为它在从 iPhone 6 开始的所有支持 NFC 的 iPhone 上都可用，而且它在所有这些 iPhone 上的工作方式都相同。
当您进入商店、餐厅、出租车或任何其他可以使用 iPhone 付款的地方时，您只需将手指放在Touch ID上，然后将 iPhone 的顶部靠近非接触式读卡器即可。或者，如果您使用的是 iPhone 12 或更新机型，请双击其侧边按钮，将您的 iPhone 放在支付终端上一会儿，然后查看您的 iPhone 以通过Face ID批准交易。
当你做这一切时会发生什么？当您将 iPhone 靠近支付终端时，它会自动开启NFC，并且在您通过Touch ID或Face ID进行身份验证后，您的 iPhone 会允许Apple Pay进行支付。
使用NFC(NFC)在 iPhone 上发起支付
这里有两个视频展示了在 iPhone 上使用NFC进行支付的整个过程：
注意：(NOTE: )顺便说一下，如果您想知道 iPhone NFC天线在哪里，它位于 iPhone 背面顶部的顶部挡板中。这就是为什么我们在上一段中告诉您“将 iPhone 的顶部靠近非接触式读卡器”。🙂
您使用 iPhone 的 NFC 芯片吗？
如今，近场通信 (NFC)(Near Field Communication (NFC))是一种越来越流行的技术。许多不同类型的设备将它用于各种目的，从简单的蓝牙(Bluetooth)关联或显示名片到在商店和其他地方付款。除了支付之外，您是否将 iPhone 的NFC功能用于其他用途？(NFC)我们很想知道，所以不要犹豫，在下面的评论部分告诉我们。
Do iPhones have NFC? How do you use NFC on an iPhone?
NFC is a popular teсhnology that’s been available fоr more than just a cоuple of years. It’s usеd everywhere, from portable speakеrs to payment systems, and for all kinds of things, ranging from tranѕferring contactѕ or files to рairing your smartphone with your car. The poѕsibilitieѕ are manу, and so are thе questions regarding iPhone’s NFC featυres. If you want to find simple answers tо queѕtions like “Is my iPhone NFC enabled?”, “Hоw do I turn on NFC on mу iPhone? or “Do I have NFC on my iPhone 12?” read on:
NOTE: If you don’t know what NFC is and why it’s so popular, we suggest you first read this article: What is NFC and what does it do?.
How to turn on NFC on an iPhone
We’re going to start bluntly: you can’t turn NFC on or off on an iPhone! Why is that? The answer is simpler than you might expect: the iPhone’s NFC function is enabled or disabled by the apps that require it. So, unlike NFC on Android, where it’s pretty straightforward to turn it on or off directly from the operating system, in iOS, there is no main switch for NFC.
NFC on iPhone is implemented differently compared to Android
Does my iPhone have NFC? What iPhones are NFC-enabled?
All the iPhones released in recent years have NFC. In fact, every iPhone since iPhone 6, which came out in 2014, has a built-in NFC chip. If you need details just to be sure, here’s the whole list of iPhones that are NFC-enabled:
- iPhone 13, iPhone 13 Mini, iPhone 13 Pro, iPhone 13 Pro Max
- iPhone 12, iPhone 12 Mini, iPhone 12 Pro, iPhone 12 Pro Max
- iPhone 11, iPhone 11 Pro, iPhone 11 Pro Max, iPhone SE (2nd Gen)
- iPhone XS and iPhone XS Max
- iPhone XR
- iPhone X
- iPhone 8, iPhone 8 Plus
- iPhone 7, iPhone 7 Plus
- iPhone 6, iPhone 6 Plus, iPhone 6S, iPhone 6S Plus, iPhone SE
iPhone 13 has NFC built-in
TIP: If you’re not sure about your model, read our guide to find out what iPhone you have.
The first generation of iPhones with NFC - the iPhone 6 models - limited this functionality to just payments via Apple Pay. However, iPhone 7 and newer models allow the use of NFC for reading NFC tags as well, using 3rd party apps.
Furthermore, starting with iOS 13 and the release of iPhone XS and XR, iPhones can also encode blank NFC tags using third-party NFC apps such as NFC for iPhone or NFC TagWriter by NXP.
And, finally, starting with iPhone XS and going all the way to iPhone 12 and iPhone 13, these smartphones are also able to read NFC tags in the background. In other words, you no longer have to install 3rd party apps and manually read NFC tags: just tap your iPhone to an NFC tag, and it will automatically identify it.
To make it easier for you to check whether your iPhone has NFC and learn what you can use it for, we made the following table:
iPhone NFC compatibility and features
By the way, all the iPhones that have NFC and are using iOS 14 or newer can automatically read all kinds of NFC tags without needing third-party apps, including but not being limited to web addresses (URLs), emails, phone numbers, and SMS messages.
How to use NFC on an iPhone
You know now whether your iPhone has NFC or not. But how do you use an iPhone's NFC? The answer is quite simple: all you have to do is tap your iPhone to another device that’s NFC-enabled. Or simply hold the top back of your iPhone close to an NFC tag. Then, the iPhone reads the NFC tag and displays a notification on its screen.
How to use NFC on iPhones: An NFC notification
Read what the NFC notification on your iPhone says and, if you want to follow it through, tap on it to perform its action. For example, if you tap your iPhone to an NFC-enabled portable speaker, you’ll get a notification to pair the two devices. If you do that, you’ll be able to output sound from your iPhone to the speaker. The whole pairing is quite faster via NFC than by manually searching for available Bluetooth devices and connecting to your speaker. A neat use case for NFC on iPhone, right?
How to use your iPhone’s NFC for payments
The best example we can give you is Apple Pay because it’s available on all NFC-enabled iPhones starting with iPhone 6, and also because it works the same on all of them.
When you go into a store, restaurant, taxi, or any other place where you can pay with your iPhone, all you have to do is rest your finger on the Touch ID and hold the top of your iPhone near the contactless reader. Or, if you have an iPhone 12 or newer model, double tap on its side button, hold your iPhone on the pay terminal for a bit, and then look at your iPhone to approve the transaction via Face ID.
What happens when you do all that? When you hold your iPhone near a pay terminal, it automatically turns on NFC and, after you authenticate via Touch ID or Face ID, your iPhone lets Apple Pay make the payment.
Initiating a payment on an iPhone with NFC
Here are two videos that show the whole process of using NFC on iPhones for payments:
NOTE: By the way, if you were wondering where the iPhone NFC antenna is, it’s located towards the top of your iPhone’s back, in the top bezel. That’s why we told you to “hold the top of your iPhone near the contactless reader” in the previous paragraph. 🙂
Do you use your iPhone’s NFC chip?
Near Field Communication (NFC) is an increasingly popular technology these days. Many different kinds of devices use it for various purposes, ranging from simple Bluetooth associations or showing business cards to making payments in stores and other places. Do you use your iPhone’s NFC features for anything else but payments? We’re curious to find out, so don’t hesitate to let us know in the comments section below.
