How to Create QR Code Generator and Reader Using Python


Published at - Nov 10, 2021

QR codes are used everywhere these days, for example, to monitor information about items in a supply chain, to take payment, and so on. Instead of using third-party QR code-generating services, let’s create our own in Python. This post will teach you how to create a QR code generator in Python.

So, in this case, we’ll employ the pyqrcode module. Let’s look at how to make a QR code in Python using the pyqrcode library.

The pyqrcode module is a QR code generator. The module automates the majority of the process of making QR codes.

Generating QR Code

Installation

pip install pyqrcode // to genrate qr code
pip install pypng // to save image in png format
pip install Pillow // for image manipulation

The above code will generate a png image with the name python-in-plain-english.png, and this is your QR code.

Output

Reading QR Code

Installation

To read QR codes, we need the ZBar tool. ZBar is an open-source software package that reads bar codes from a variety of sources, including video streams, picture files, and raw intensity sensors. Many prominent symbologies (bar code formats) are supported, including EAN-13/UPC-A, UPC-E, EAN-8, Code 128, Code 39, Interleaved 2 of 5, and QR Code.

sudo apt-get install zbar-tools

Other Python Modules

pip install pyzbar // to read qr code
pip install pyqrcode // to genrate qr code
pip install pypng // to save image in png format
pip install Pillow // for image manipulation
