Quite likely, someone will be knocking at your door a few weeks from now and asking for your fingerprints. If you agree, your fingerprints will enter a national database, along with personal characteristics (age, sex, occupation, and so on) that have already been collected from you, unless you were missed in the “Census household listing†earlier this year.
The purpose of this exercise is to build the National Population Register (NPR). In due course, your UID (Unique Identity Number, or “Aadhaar†) will be added to it. This will make it possible to link the NPR with other Aadhaar-enabled databases, from tax returns to bank records and SIM registers. This includes the Home Ministry’s NATGRID, smoothly linking 21 national databases.
