Staqu worked with police stations to digitize their existing criminal records, and created a system that would let cops use an
Android smartphone to click a picture of people they arrest, and log their demographic data, voice samples, and fingerprints into a national, searchable database. Staqu’s system is now used by police stations in eight Indian states. Rai claims that there are over a million records in the database so far, and police officers across the country are adding 1,000 more to the system per day.
