Scanning QR Codes on i Phone: You have certainly already come across one of these funny grids resembling a pixelated image. These are QR codes. But do you know that it is possible to scan them with your iPhone camera? Here’s how to use them.
What is a QR Code?
Public transport, advertising posters, newspapers,
magazines, QR codes are everywhere. They gradually invaded the urban
environment. But for ordinary people this white square filled with small black
spots remains very mysterious.
This is actually an evolution of the barcode found on cereal
boxes or on laundry packages. But unlike its ancestor, the QR code (Quick Reponses)
is capable of storing much more information.
The arrangement of small black dots allows you to code all
kinds of content. This can be the URL of a web page, the location of a location
on Google Maps, or data from a virtual business card. The possibilities offered
by this type of technology are limitless.
But for the rest, the principle is the same as with a
traditional barcode. To read a QR code, simply place the square in front of the
photo lens of your iPhone, taking care to aim the image. Once scanned, the
iPhone will display all the information contained in the QR Code. In most cases
it is a web page.
Then you just have to click on the link. The page will automatically
open in Safari. This eliminates the need to manually type in the (sometimes
complex) URL of a website.
A few months ago, the iPhone could not read QR codes. To
decrypt these curious little squares, users had to install a dedicated
application. Fortunately, with the arrival of iOS 11 things have changed.
The camera’s native app now offers a reader module capable
of scanning QR codes. This function is activated by default on all terminals
with iOS 11. It is still necessary to know how to use it.
How to read a QR code with your iPhone
Before you start, make sure your iPhone has the latest
version of iOS in order to use the latest features of the Camera app. For that
click on Settings then on General and finally Software update. A message will
notify you of the availability of a possible update for your smartphone. Don’t
forget to make a backup before installing the update.
Launch the Photos app
Place the camera lens in front of the QR code to be scanned
Wait 2 to 3 seconds without pressing the shutter button
A notification will appear at the top of the screen. Then
simply click on it to display the content of the QR code.
Use Google Chrome to scan a QR code
Surprisingly, the Google Chrome browser has a function for reading
bar codes. Please note, this functionality necessarily requires the 3D Touch,
i.e. having an iPhone 6S or higher.
Tap the Chrome shortcut icon on your phone’s home screen
A new menu will appear with different options
Click on QR code scanner
Place your device in front of the bar code

The different methods proposed in this article will allow
you to read a QR code and access very quickly the content associated with it.
In addition, these tips will save you from having to install an additional
application. With the advent of 4K videos and live photos, storage space has
become a scarce commodity. Not everyone can afford an iPhone with 128 GB.

This feature is enabled by default on the iPhone. If you
don’t need it, be aware that you can turn it off.
