Using QR codes is still foreign to some people, especially non-techie ones. But you might have already learned how to scan a QR code. You definitely would have noticed its presence on product packaging, billboards, or restaurant menus.
QR code was first used in 1994 by the manufacturing company Denso Wave. It was originally intended to improve components' scanning and to track time during the assembly procedure. Now, it has been adopted by various industries.
Best QR codes keep up with the times to provide new ways to reach customers, transmit information, and direct people to your website. The easiest way to explain how a QR code works is it types a web address into your browser, making every transaction fast and convenient.
The components of the QR code are mentioned below:
QR codes are square-shaped black and white pixels that contain a string of data. When you scan them, it will translate the unique pattern to give you human-readable information.
Have you tried scanning a barcode before? If yes, then you already know how to scan a QR code. What sets it apart is the device used to read the code and its linear arrangement. QR codes can also keep more data since they're written vertically and horizontally.
What makes up the best QR code? Let's discuss them below:
You don't need a particular device when scanning a QR code. An iPhone or Android phone camera will show you the content of the code when you point the camera app at it. If you're not online and you need to access the QR code, you can save it first in your gallery and scan it once you go online.
You may go to your apps list or use the Camera app shortcut. Just hold the camera icon from your lock screen to open it.
Hold the phone so that the entire QR code is visible in the frame. You don't have to take a snapshot of it.
Once the app reads the code, a notification will pop at the top of your screen. Click on it and follow the link it showed.
You need access to the internet to be able to open the link. If you don't have it, take a picture of the QR code to scan it later.
If you didn't receive any notifications, ensure that the "Scan QR code" feature is on in your Camera app. It is on by default but could also be disabled. Know more about how to scan the restaurant menu on iPhone.
