walkins were never going to work if they were going to ask the otp from the person on the window. this is what you get with digitization. we have extensive experience of this mess with aadhaar. they still haven't found a way to help people who do not remember their aadhaar number and the mobile number that it was associated with. UIDAI has no way to find out your aadhaar number. All those news reports about Aadhaar helping kids finding their lost families using their fingerprints was all fraud.
