A. Does scanning the QR Code require the internet?
Technically, the answer to this question is no. You don’t really need to have an internet connection to simply ‘Scan’ a QR Code.
A QR Code stores data in the tiny squares called the data matrix. Scanners simply need to read them to decode the encoded data.
But if you’ll actually be able to see the target content depends on whether the QR Code is static or dynamic.
1. Static QR Code
A Static QR Code stores the target content directly. It could be text, numbers, alphanumeric data, and even web links.
Since the data is stored directly, these QR Codes can’t be edited once you’ve created them.
In addition, you don’t need an internet connection to scan these QR Codes. On scanning, you’ll see the encoded content on your device.
However, if the QR Code contains a web link, you’ll need the internet to be able to open it.
That means while the scanners will be able to decode the QR Code to show you the web link, you’ll need the internet to load the webpage.
2. Dynamic QR Code
As the name suggests, dynamic QR Codes are not permanent in nature. That means you can edit them anytime after having created them.
This is because a dynamic QR Code stores a redirecting URL. This URL takes the end-users to the target content.
Hence, you’d need an internet connection to load the content encoded in it. While you’ll be able to see the redirecting URL on scanning the QR Code without the internet, you’ll not be able to see the target data.

You must be thinking—what content can exactly be shared via QR Code without an internet connection?
Well, here are some examples for you:
1. Simple text
You can add simple text to the QR Code. It could be a quote, product details, user guide or manual, or any other textual detail.
When end-users scan the QR Code, they will be able to see the encoded text easily. No internet connection is required.
However, note that you’ll be able to add only up to 7,098 alphanumeric characters. If your use case needs you to add more information, you’ll have to create a Rich Text QR Code that is dynamic in nature.
2. Numbers and special characters
You can easily create a QR Code having numbers or special characters or both. These can be static in nature and, hence, would scan perfectly well without an internet connection.
3. Phone number, email, and SMS
You can even create a Phone number QR Code which, when scanned, will show a pre-populated phone number. No need for any internet connection.
Similarly, you can also generate an Email QR Code or even an SMS QR Code. When scanned, it will show a pre-populated email or text message on the end-user’s phone.
4. Static Business Card
You can also add your contact details to the QR Code. For example, name, email, phone number, address, etc.
However, since a static QR Code has a character limit, you may not be able to store as many details as you want.
In addition, the more details you add, the denser your QR Code will become. And if it gets too cluttered, your QR Code’s scannability will be severely affected.
Here’s a quick video on various types of QR Code categories:
C. Some QR Codes that need an internet connection to work
