通常，当有人来到您家并要求连接到您的WiFi时，如果您不记得密码，您要么去找密码，要么继续手动将他们连接到网络。此外，当您遇到一个新人并想要他们的联系信息(contact info)时，您通常会交换号码，互相打电话，然后使用该人的信息创建一个新联系人。
这可能不会很快改变，但是我们的手机内置了很酷的新技术，你绝对可以通过简化这个过程来让自己脱颖而出。一位朋友最近告诉我一个免费网站，可以让你创建自己的二维码，用于各种不同的用途。如果您不确定 QR 码是什么，请查看Wiki 条目(Wiki entry)。
那么，生成自己的二维码(QR code)到底有什么用呢？好吧(Well)，对于那些运行最新版本的 iOS (11) 的人来说，二维码(QR code)更加有用，因为默认的相机应用程序(default camera app)现在可以自动读取它们。这意味着无需下载单独的应用程序来扫描二维码(QR code)。
此外，在 iOS 11 中，它不仅可以扫描二维码(QR code)，还可以让您将这些数据合并到您的手机中。例如，如果您使用您的WiFi凭据创建一个二维码，(QR code)任何扫描(anyone scanning)该二维码的人都将能够自动连接到您的WiFi，而无需手动输入密码等。不幸的是，对于Android用户来说，它并不容易使用. 这取决于您拥有的手机、您运行的Android版本等。(Android)
创建自定义二维码
您要做的第一件事是创建您的自定义二维码(QR code)。最好的方法是使用一个名为QRCode Monkey的免费网站。它完全免费且超级易于使用。我真的在大约 2 分钟内创建了我的第一个二维码。(QR code)
在顶部，您会看到可以创建的不同类型的二维码：URL、文本(Text)、电子邮件(Email)、电话(Phone)、短信(SMS)、VCARD、MECARD、位置(Location)、Facebook、Twitter、YouTube、WiFi 或活动(WiFi or Event)。在本文中，我将为您提供WiFi 和 VCARD(WiFi and VCARD)的示例，因为这两个是我在智能手机上测试的。
单击(Click)VCARD并将版本保留为 2.1 。版本 3(Version 3)可能适用于 iOS 11，但我没有对其进行测试。现在输入您想要存储到二维码(QR code)中的所有信息。如您所见，您可以添加相当多的信息。
因此，您可以在几秒钟内快速分享所有这些信息，而不是仅仅与某人分享您的电话号码并拼出其他所有信息，我将在下面向您展示如何操作。输入内容后，他们可以选择更改颜色、添加徽标图像、自定义形状等，但我没有搞砸(t mess)这些。继续(Just)并单击右侧的创建二维码按钮。( Create QR Code)
您应该看到设计更改(design change)，现在它会有一大堆更小的点。您现在也可以点击下载 PNG( Download PNG)按钮或下载SVG、PDF 或 EPS(PDF or EPS)文件格式的二维码(QR code)。
字面意思就是这样！您现在已经创建了您的自定义二维码(QR code)，您可以将其打印或复制到您的手机上。就我而言，我只是将PNG 文件(PNG file)通过电子邮件发送给自己，然后在我的 iPhone 上打开它。然后，我将图像保存到我的相机胶卷(camera roll)中，然后进入我的 Notes 应用程序，并将QR 码(QR code)与标题一起插入到新便笺中，以识别它存储的信息。
您现在可以将此 QR 插入您喜欢的任何地方供人们扫描。你可以把它放在你的网站上，把它打印在你的名片(business card)上等等。创建其他二维码也很容易。我最喜欢的是WiFi。单击(Click)它并输入您的无线 SSID(Wireless SSID)和密码，然后为您的网络选择加密类型。
创建二维码并下载(QR code and download)图像。既然您知道如何快速轻松地创建用于各种目的的 QR 码，那么让我们来谈谈如何使用它们。
使用智能手机扫描二维码
现在是有趣的部分：扫描您的二维码(QR codes)。正如我之前提到的，如果你的iPhone 或 iPad(iPhone or iPad)上安装了 iOS 11，整个练习会更有趣。对于Android用户，您必须下载一个QR 扫描(QR scanning)应用程序，该应用程序没有那么有用或无缝。
在您的 iPhone 上，继续打开普通的相机应用程序(camera app)。确保您在Photo或Square上。现在只需将您的相机对准二维码(QR code)，您就会看到一些神奇的事情发生！二维码(QR code)可以在手机显示屏(phone display)、电脑屏幕上(computer screen)，也可以打印出来，没关系。
如您所见，我只是将我在网站上创建的二维码(QR code)放在相机前，顶部会出现一个标题为Contacts QR Code的通知。只需点击(Just tap)它然后砰，它会打开一个新的联系人屏幕(contact screen)，其中您之前输入的所有信息都已经填写完毕！只需单击(Just click) 保存(Save)即可完成。好消息是您甚至不必按下按钮来拍照，它只会看到二维码(QR code)并自动解释它。
当您扫描WiFi 二维码(WiFi QR code)时，也会发生同样的精彩！只需点击(Just tap)它，它就会将您加入该网络！您不必打开您的WiFi设置或任何东西。它实际上很酷。如果您的手机上安装了 iOS 11，您绝对应该尝试一下。显然，没有安装 iOS 11 的 iPhone 的人不会对此印象深刻，但对于那些拥有 iOS 11 的人来说，这就像魔术一样。希望(Hopefully)未来的Android版本将支持与 iOS 相同级别的QR 码(QR code)集成。享受！
How to Share WiFi Credentials and Contact Info using QR Codes
Normally, when someone comes to yоur house and they ask to connect to yoυr WiFi, you either go find the password if you can’t remember it or you go ahead and manually connect them tо the network. In addition, when you meet someone new and want their contact info, уou normally exchange numberѕ, cаll each other and then create a new contact with the person’s info.
This will probably not change anytime soon, but with cool new tech built into our phones, you can definitely make yourself stand out by making this process much simpler. A friend recently told me about a free website that lets you create your own QR codes for a whole bunch of different uses. If you’re not sure what a QR code is, check out the Wiki entry.
So, how is generating your own QR code actually useful? Well, for those running the latest version of iOS (11), QR codes are way more useful because the default camera app can now read them automatically. That means there is no need to download a separate app just to scan a QR code.
In addition, with iOS 11, not only will it scan the QR code, it will also allow you to incorporate that data onto your phone. For example, if you create a QR code with your WiFi credentials, anyone scanning that code will automatically be able to connect to your WiFi without having to manually type in the password, etc. Unfortunately, for Android users, it’s not as easy to use. It depends on the phone you have, the version of Android you are running, etc.
Create Custom QR Code
The first thing you’ll want to do is create your custom QR code. The best way to do this is to use a free site called QRCode Monkey. It’s completely free and super easy to use. I literally created my first QR code in about 2 minutes.
Across the top, you’ll see the different types of QR codes you can create: URL, Text, Email, Phone, SMS, VCARD, MECARD, Location, Facebook, Twitter, YouTube, WiFi or Event. In this article, I’ll give you examples of WiFi and VCARD, as those are the two I tested on my smartphone.
Click on VCARD and leave the version at 2.1. Version 3 will probably work with iOS 11, but I didn’t test it. Now enter all the information that you want to store into your QR code. As you can see, you can add quite a bit of information.
So, instead of just sharing your number with someone and having to spell out everything else, you can quickly share all of this information in a few seconds, which I’ll show you how to do below. After you enter the content, they have options to change the colors, add a logo image, customize the shape, etc., but I didn’t mess with any of that. Just go ahead and click on the Create QR Code button on the right-hand side.
You should see the design change and now it’ll have a whole bunch of smaller dots. You can also now click on the Download PNG button or download the QR code in SVG, PDF or EPS file formats too.
That’s literally it! You have now created your custom QR code, which you can print or copy to your phone. In my case, I just emailed myself the PNG file and opened it on my iPhone. I then saved the image to my camera roll and then went into my Notes app and inserted the QR code into a new note along with a heading to identify what information it is storing.
You can now insert this QR anywhere you like for people to scan. You can put it on your website, print it out on your business card, etc. It’s also really easy to create other QR codes too. My favorite one is WiFi. Click on that and enter in your Wireless SSID, password and choose the type of encryption for your network.
Create the QR code and download the image. Now that you know how to quickly and easily create QR codes for various purposes, let’s talk about how you can use them.
Scan QR Codes using Smartphone
Now for the fun part: scanning your QR codes. As I mentioned earlier, this whole exercise is a lot more fun if you have iOS 11 installed on your iPhone or iPad. For Android users, you’ll have to download a QR scanning app, which isn’t as useful or seamless.
On your iPhone, go ahead and open the normal camera app. Make sure you are on Photo or Square. Now just aim your camera at the QR code and you’ll see some magic occur! The QR code can be on your phone display, computer screen or printed out, it doesn’t matter.
As you can see, I just put the QR code I created on the website in front of the camera and a notification appeared at the top titled Contacts QR Code. Just tap on that and bam, it’ll open a new contact screen with all of the information you typed in earlier already filled out! Just click Save and you’re done. The nice thing is you don’t even have to press the button to take a photo, it just sees the QR code in view and automatically interprets it.
The same awesomeness happens when you scan the WiFi QR code! Just tap on it and it will join you to that network! You don’t have to open your WiFi settings or anything. It’s actually pretty cool. You should definitely try this if you have iOS 11 installed on your phone. Obviously, someone who doesn’t have an iPhone with iOS 11 will not be super impressed, but for those that do, it’ll be like magic. Hopefully, future versions of Android will support the same level of QR code integration like in iOS. Enjoy!
