Earlier this month, the Consultative Group to Assist the Poor (CGAP) hosted a fascinating event featuring Ashok Singh, the Deputy Director General at the Unique Identification Authority of India (UIDAI). The focus was on how these unique ID numbers, or Aadhaar numbers, which are issued after iris and fingerprint scans are employed to ensure each individual is unique to the system, can provide a means for financial inclusion for the poor. Remarkably, Singh, said, UIDAI is issuing Aadhaar numbers at the rate of 1 million a day, with a goal of 600 million over the next four years.
