Why use QR codes?
There are various ways you can create and use these QR codes. Let me highlight a few of them for you:
- UPI Payment Transaction
- Share your social media accounts
- Post a coupon
- Share a food or service menu
- Collect reviews or feedback
- Provide product information
What are Static QR Codes?
Static QR Codes are hard coded. Once produced cannot be changed. Best suited for providing an email address or contact information.
What are Dynamic QR Codes?
A Dynamic QR Code is a QR Code that points to a static URL that contains the actual content (e.g., the real URL). Dynamic QR codes are mostly used for sharing a link to a webpage. They do not keep the data but instead redirect the scanner. However, they are not confined to just web pages. Dynamic QR codes can also link to a voucher, event website, PDF, or SMS text message. You can change the contents or type of dynamic code without generating new code if necessary. As a result, dynamic codes are ideal for marketing campaigns.
How to create a Free QR Code Generator using Python
Following is a step-by-step guide on how to create a QR code in python in just three simple steps. I am using google colab notebook to execute the following lines of code. You can open your colab and follow along with this guide.
Step 1: Install the required library
Use the below pip command to install pyqrcode and pypng python libraries before proceeding.
!pip install pyqrcode!pip install pypng
Once the libraries are installed, it’s time to import them and see the magic.
Step 2: Import the required library
We will import the QRCode module from the pyqrcode library to generate the QR code.
Also, we are importing png for saving and loading PNG images.
import pyqrcodeimport pngfrom pyqrcode import QRCode
Step 3: Use the library to generate the QR
Using pyqrcode, pass the URL that you want the user to access when he scans the generated QR code.
url = 'www.shiksha.com/online-courses/articles' url = pyqrcode.create(url)
url.svg('qr.svg',)url.png('qr.png', scale = 8) //Scale to magnify
Booom!!
This is the generated QR Code. Scan it to see the result.
Conclusion
Now you know how to create a QR code. Next time when you want to use it, have a goal in mind. You don’t have to use QR codes just because you’ve read them. Make sure you’re using codes to help with your marketing or to improve customer experiences, not just because it’s a new marketing trend.
