The setup
The enrollment officer (EO) sits at right angles to you and enters data into a laptop. The insight of the Aadhaar team here is that the person getting enrolled must see what is being entered. Thus there's a monitor in front of you, which mirrors the enrolment officer's screen so that you can point out spelling mistakes or other errors. If the person getting enrolled is illiterate, he or she can nominate someone to accompany and verify. There's a small laser printer behind the EO's laptop and a webcam, fingerprint reader and iris scanner account for the remainder of the hardware setup. Unless, of course, you count the light bulb hanging from the ceiling and a white "roll-up" chart behind you for the "passport photo studio" effect!
Compulsory information
Name (first and last name compulsory but middle name optional), Gender (Male/Female/Transgender) and Date of Birth are the compulsory fields. Whereas postal address is also required, it's more for the sake of mailing your UID number than strictly being a proof of residence. The EO asks you for a PIN code and the city/district fields are automatically populated. The rest of the address is entered manually.
Supporting documents
The UID team acknowledges the fact that a large number of people may not have any supporting documents to prove their identity. In this case, one is allowed to bring another resident who is already in possession of an Aadhaar number to be an "introducer" by vouching for the person seeking to enroll. Of course, there is scope for fraud either with a colluding introducer or by just using fake supporting documents. However, the whole point of Aadhaar is that one can only fake one's identity once and this prevents large-scale "ghost identity" creation, which is the bane of most Indian government schemes. The great PAN (Permanent Account Number with the Income Tax department) card scam after all involved a single person creating thousands of different PAN numbers.
Photograph
A photograph is taken of the person getting enrolled, purely for the purpose of printing it out on the enrolment receipt, so that illiterate residents have some way of knowing that the receipt indeed belongs to them. Beyond that, the photograph serves no biometric or authentication purpose.
Biometrics
First there's an iris scan where you look into a binocular-like device held up to your eyes by the EO. After that it's the four fingers of each hand, followed by both thumbs (a process familiar to those entering the US) for your 10 fingerprints.
The wait
The EO makes you review the data entered one final time before giving you a laser-printed receipt. Whereas the residents of Tembhali, the "Aadhaar village", were to get their numbers today, the rest of us won't be that lucky. We'll only get to walk away with our receipts and have to wait for the actual number to be delivered by India Post!
