Read Adhar number from the QR Code ?

[dwishaventures]

Hi Tanmoy,

Can we read the Adhar Number from the QR code ?

Thank you.

[tanmoysrt]

In the latest QR codes , UIDAI doesn't allow access to full aadhaar no . You can get only the last 4 digits of an aadhar card. But for old QR codes, you can access full aadhar no / uid . Thanking You Tanmoy Sarkar Founder of Quikshope ᐧ

Hi Tanmoy,

Can you tell me where to find the key names contained in a new aadhaar QRcode please ? I coudn't find any specific documents in https://uidai.gov.in/

key names in old aadhaar QRcode are shown in the red square:

Thank you.

If you want to use pyaadhaar library, You need to use

from pyaadhaar.decode import AadhaarSecureQr

obj  = AadhaarSecureQr(<:Data got from QR:>)
print(obj.decodeddata())

If you want to understand how to extract data from the encoded string of latest secure qr, please go through this PDF and the implementation of AadhaarSecureQr function

If you have any doubt, feel free to reach me .

Thanks a lot for your generous help! The PDF does help.

Which data format should I send in as <:Data got from QR:>?

[tanmoysrt]

Scan the qr, you will get data in binary format consisting of numbers only. Pass that data as a string.

masking adhar Qr code decode ? is possible

[tanmoysrt]

@sahiljadhav123 I haven't tested actually, I need to check
There were not any specific docs at all for masked aadhar card.
I will check and update you

[sahiljadhav123]

One more issue- invalid literal for int () base 10 :

[tanmoysrt]

I will check the issues and will try to resolve them and release a new version. For the past few months, can't get time to release the new version

[tanmoysrt]

OK I will check and let you know

Sorry, You need to pass the raw data directly to that function. The long integer that you got from QR code. No need to convert to string explicitly. ᐧ

Describe the bug
When I try to retrieve the QR data from new aadhaar QR code it throws error as 'string out of index'. Whereas if i try with old aadhaar QR code data, I am getting the correct expected output.

Expected behavior
For the new QR Code also i must get the proper result without error. I have updated my pyaadhar package to 2.0.2 and also my python version is 3.12

Additional context
But as per your new release you have mentioned as, it supports the old and new both aadhaar QR codes.
Could you please help me in sorting out this.

[tanmoysrt]

I am not able to find current specs of secure aadhar QR.
If specs has been changed, then it's a issue with parsing.

If you found the specs sheet, send here also

Hey Tanmay,
Thanks for your response.
Even we are using the same user manual which you've referred to. We too didn't find any updated document for the same.
Anyways I have tried a different approach to handle QR data based on the different versions. I have enhanced the decode.py file's AadhaarSecureQR function and it is able to extract the data for both old and new aadhaar QR codes. I'm sharing you the file regarding the same, PFA. But as we are using pyaadhaar library, the decode.py file is under that, so changing the function code in library package is not a feasible solution when it comes to deploying to other servers. Anyways my updated works in my local system server. But the problem arises in other servers. Please go through my code once and see if that can be helpful for you too to integrate with your library function. Also I'm attaching a document regarding the changes I made.
