The Bharat Interface for Money (BHIM) reveals the story of how Young India is functioning to take the country forward. By Monday evening, BHIM made it to the 'top free apps' chart of Google Play Store in India, beating popular apps such as WhatsApp, Facebook, and Facebook Messenger. For about two months till the launch of Bhim, more than a dozen people at a New Delhi company slogged it out, spending sleepless nights to ensure that the app was safe and that the security loopholes were plugged before it went live. This dedicated team comprised employees of Lucideus Tech, one of the cybersecurity companies that provided security for the app developed by the National Payment Corporation of India and launched by the Prime Minister on Friday. "We literally worked all night for the last few weeks on the app. Over a dozen people at Lucideus were working exclusively on this," said Saket Modi, chief executive of the company. Lucideus has in the past worked with organizations such as ICICI Bank, Standard Chartered, IndiGo, and KFC.
