"People who have received these numbers will look for the benefits of the number. This is where the app ecosystem will come in. Different partners can build apps and provide benefits across different sectors like healthcare and banking," Nilekani said.
Nilekani, who co-founded India's second-biggest tech firm Infosys three decades ago, on Thursday opened the Aadhaar platform for thousands of software developers to build applications linking these unique identity numbers with different services. On its own, an Aadhaar number will be a mere 12-digit identity, but by linking it with services offered by mobile phone companies, ration shops and banks, the government plans to deliver citizen utilities faster and better.
"It's really up to the imagination and innovation of the people," Nilekani told dozens of software developers in Bangalore gathered for the UID conference. "In some sense we believe it will be game changing...we don't see this project just as giving someone an ID card. This will create a national-level online identity management platform," he added.
The government launched an application programming interface (API), which will allow developers write applications that can work with Aadhaar. These developers will earn money for every transaction conducted using their applications.
For Aadhaar to solve the identity crisis for millions of Indians, hundreds of applications will need to connect it with service providers across government departments and private sector firms. For instance, research firms and experts reckon that nearly 500 million Indians are out of the banking system and more than half of India's farmers do not have access to credit from formal banks.
Software applications can link these numbers with a bank's system and help it establish identity before offering a loan or opening a new savings account. Research firm CLSA estimates that the UID exercise can bring nearly 125 million people into the banking system over the next five years. These folks, according to CLSA, are primarily from poor, below the poverty line (BPL) families who otherwise will have no way to prove their identities.
Already, the Reserve Bank of India and the ministry of finance have issued guidelines to banks to use Aadhaar as an identifier. The telecommunications department and the oil ministry too have issued similar guidelines.
"In some way you are opening up all the products and services for people," said Nilekani.
Pilot applications are already being tested by companies such as Pune-based Persistent Systems and Feecounter Online Services.
Feecounter Online Services is a 350 employees start-up based out of Pune. Mitesh Ajmera, a former employee at the Citi Bank , is the company's CEO. The company offers an online portal for the payment of school fees. "With this initiative, school fees can be directly credited from the individual's bank account to the school's account. The idea is to eliminate transaction costs. Also, the whole idea of waiting in a queue for long hours can be skipped," said Ajmera. One of the potential applications being tested will build an entire payment gateway for Aadhaar-based transactions, said an official at a company writing that application.
