These are open-source python libraries that help in decoding bar codes and QR codes. The main libraries that we shall need are the pyzbar and zbar libraries to decode our encrypted QR codes. Now that we know what QR codes are, let’s get started with our python code.įor our project, we are going to use OpenCV to read images, take video stream input and also display our output. Thus QR Codes are more powerful than Bar Codes. A QR code is considered to be a 2D bar code as it can store data both horizontally and vertically as opposed to Bar code which usually stores data in the horizontal direction. This acts as an added layer of protection to prevent the misuse of sensitive information.īar codes much like QR Codes are also machine-readable encrypted codes but unlike QR codes, the data is encrypted in the form of bars of different spacing and thickness. First, let's start by generating QR codes, it is basically straightforward using qrcode library: import qrcode example data data ' output file name filename 'site.png' generate qr code img qrcode.make(data) save img to a file img.save(filename) This will generate a new image file in.

In this step, we will install the following three libraries: Pillow, OpenCV and Pyzbar. If you are wondering how barcode and QR code readers work, let’s do a quick real-life practice. One of the main advantages of QR codes is that the data can be shared in encrypted form without having to reveal the encoded data explicitly.

Sharing payment information (GPay, Paytm).Tracking individual items (Inventory Management).Identification and authentication if users ( ID cards).QR Codes find their application in various fields such as:
