5 Interesting Facts About QR Codes

Years ago, when QR codes first appeared, they were announced not only for the inevitable barcode successor but also for the future of sharing information. By scanning a code, you can open a web page without entering a URL, learn more about a product, shop in virtual stores, unlock levels in video games, and so on.

Unfortunately, many people are not aware of the benefits of QR codes and how to scan them. Despite their obvious benefit, QR codes do not enjoy the success they deserve. This may change soon. Let’s see 5 interesting facts about these small images.

1. QR codes are great for detecting applications

If you’ve ever bought a drone, a smart watch, or something like that, you probably had to install some companion application. Just that there is a problem: traditional search in the Apple App Store or Google Play Store may be useless as there are often dozens of applications with similar names. You may end up with the wrong application or simply fail to match your search query.

Fortunately, many instruction manuals already include QR codes that will take you to the exact application. This is not just a huge saving of time but also of nerves. You will surely get the application specifically designed for your product.

2. QR codes help us while shopping

QR codes makes shopping easier, but they are so small that most buyers will probably not notice them or they will not know what to do with them. In fact, they can provide you with very valuable information about the product you are interested in.

3. QR codes for access to your Wi-Fi network

Your router may already have a QR code at the bottom. If not, consider creating one that contains your SSID, password, or other important information. You can do this easily with an Android device using the free QR Code Generator – Wi-Fi Access service. Just include the relevant data, create the code, and then download the resulting PNG image. You can then print a copy to the router or other convenient location so you can share this information easily.

4. QR codes will be supported natively in iOS 11

Not officially reported, but iOS 11 is likely to include automated scanning of QR codes. You’ll only need to turn on the Camera app and direct the camera to the code. Scanning will decode the built-in text and allow you to take action, such as visiting a web page or accessing a Wi-Fi network.

If you do not want to wait, if you use Chrome for iOS and have an iPhone that supports 3D Touch, you can scan QR codes by clicking on the Chrome icon and choosing this option from the popup menu. Of course, there are many third-party scanning applications for both iOS and Android which can read the information from QR codes.

5. You can create your own QR code for almost everything

Thanks to sites such as QRstuff.com, you can create codes for dozens of different actions: dial a phone number, skype call, play a video on YouTube, and so on. You can even add some color to your code.
