![]() Here are the issues I am facing with these libraries: Secure_qr = AadhaarSecureQR(int(qrData))ĭecoded_secure_qr_data = secure_qr.extract_data() # secure_qr = AadhaarSecureQR(integer_scanned_from_qr) Python version: 3.8 from pyaadhaar.utils import Qr_img_to_text, isSecureQrįrom ocde import AadhaarSecureQrįrom ocde import AadhaarOldQr Here is my code for decoding secure QR code using these libraries. Please recommend possible resolutions or some other methods to achieve this task Information on Secure QR code is available here. ![]() I am unable to decode Secure QR code using them on Aadhaar cards. These 2 libraries seem particularly useful for this use case: To extract the info - I have been looking into python libraries that read and decode Secure QR codes on Indian Aadhaar cards. I am able to identify the region with QR code. You’ll also get full access to every story on Medium.I am trying to extract the complete Aadhar number (12 digits) from the image of an Aadhar card (India) Your membership fee directly supports me and other writers you read. ![]() I hope you like the article, I would highly recommend signing up for Medium Membership to read more articles by me or stories by thousands of other authors on variety of topics. ![]() Resources:Ĭode for the tutorial is available in my GitHub Repo. You can refer OpenCV QRCodeDetector class reference for more information on reading QR code using OpenCV. The detectAndDecode function returns the content of the QR code, coordinates of the corners of the box and binarized QR code. import cv2 img=cv2.imread("medium.png") det=cv2.QRCodeDetector() val, pts, st_code=det.detectAndDecode(img) print(val) Output: QR code can be decoded using detectAndDecode function of QRCodeDetector object of OpenCV. If the package is not installed, it can be installed as below: pip install cv2 qr = qrcode.QRCode( version=1, error_correction=_CORRECT_L, box_size=10, border=4, ) qr.add_data(" ") qr.make(fit=True) img = qr.make_image(fill_color="red", back_color="black") img.save("medium.png")Īdvanced QR Code (Image by Author) Reading QR Code The following code generates a QR code which points towards my medium profile. It can also be used to set the fill color and background color of the QR code using fill_color and back_color arguments. make image This function generates the QR code. make If you are not sure about which version of QR code to use, the version can be set automatically by : a. add data The content of the QR code can be passed as an argument to this function. The QRCode object has the following functions which can be used to create the QR Code. border: This parameter controls the thickness of the border. box_size: This parameter controls the number of pixels in each box of the QR code ERROR_CORRECT_L: up to 7% ERROR_CORRECT_M: up to 15% ERROR_CORRECT_Q: up to 25% ERROR_CORRECT_H: up to 30% This varies from 7% to 30% error correction as below. error_correction: This parameter controls the Error Correction used for the QR code. Version 1 will create a 21X21 matrix QR Code. 1 being the smallest and 40 being the largest. version: There are 40 versions of QR code which controls the size of the code. QR code can be customized using QRCode object which has the following parameters: You can use your smart phone to read the above code.Ĭaution: Do not use your phone to read random QR codes as it may contain malicious code/links. ![]() QR Code For Hello World (Image by Author) The below code produces a QR code which reads ‘Hello World.’ #Import Library import qrcode #Generate QR Code img=qrcode.make('Hello World') img.save('hello.png') Simple QR CodeĪ simple qr code can be generated by using the make function of qrcode and passing the data as argument. pip install qrcodeįull documentation of the package can be accessed in PYPI homepage of the package. The first step is installing the package using pip command. Install QR Code module We will be using qrcode package for generating QR code. In this article we will learn how to read and generate QR Code using python. QR Codes have become so popular that now every new smartphone comes with in built QR code reader. Nowadays, QR codes are being used for wide variety of applications like, make online payments, check hotel menu, share wifi password, obtain price and other details of products etc. QR Code has increased in popularity in the later 2010s with improvement in optical capabilities of mobile phones and their wide adoption. QR code was invented by a Japanese engineer Masahiro Hara from automobile manufacturer Denso Wave in the year 1994 to track the movement of car parts. QR codes are machine readable two dimensional pixelated barcodes which can be used to store a variety of information.
