India is building a biometric database for 1.3 billion people — and enrollment is mandatory - LA Times
The LA Times reports: "Nearly 9 out of 10 Indians have registered, each assigned a unique 12-digit number that serves as a digital identity that can be verified with the scan of a thumb or an eye. [...] Designed as a showcase of India’s technological prowess — offering identity proof to the poor and reducing waste in welfare programs — Aadhaar’s grand promises have been muddied by controversy as the government makes enrollment mandatory for a growing number of essential services. [...] Soon, as more private companies use the database, it could become difficult to open a bank account, get a new cellphone number or buy plane or train tickets without being enrolled."

Comment: This sounds like a privacy nightmare but it's certainly an interesting experiment in government mandated identity verification.  If India can make it work it will become an attractive option for many other countries.
