Last week, the government managed to pass the Finance Bill, which made Aadhaar mandatory for services from getting a SIM card to filing taxes. Yes, the same Aadhaar that makes a database of citizens’ fingerprints and iris scans, and that until recently was optional.

Aadhaar is on it’s way to becoming the only identity card in the future. But, a major component is biometric identification technology, and technology can always fail. What happens if a software cannot recognise you? Or what if you don’t have biometrics that can be scanned?
