  1. Same on Google Pay. If you know what the license plate number is and the bank from which the fastag is (usually printed on the tag, which is visible through the windshield), you can see anyone’s fastag balance.

  2. When I was in uni, we could pay fees through paytm portal. When you enter your roll no. You had to confirm your name, phone and some other stuff. CONFIRM, NOT WRITE(It was a checkbox).

    Using this exploit, we knew everyone’s phone number and name just by their roll no. I’m not sure if many people knew this, since we kept this exploit a secret so that people can’t use it for wrong reason. I even raised a complaint to my uni, but nothing was done.

    I’m guessing this is fixed now, or this is a serious data breach. This was 6 years ago

  3. Bro download the Official Challan app (or something similar named I forgot) but you can literally enter any vehicle number and see their traffic challan. Their photo, registered name, vehicle, financier info, etc. EVERYTHING is widely available. its insane.

  4. If they happen to have an HDFC FasTag and you happen to know their date of birth, you can then go to and find out their phone number, name and postal address… and PAN number.


    (also you can try 366 times if you know their year of birth, for example if they went to college with you)

    Fucking incompetent privacy-retarded Indian tech stack, man.

    EDIT: and if you know their PAN, you can find their Aadhar because of mandatory Aadhar-PAN linkage requirement of our dear Income Tax department.
