"India may have leapfrogged the US technology industry with simple and practical innovations and massive grunt work. It has built a digital infrastructure that will soon process billions more transactions than bitcoin ever has," Vivek Wadhwa wrote in an op-ed in The Washington Post.
"With this, India will skip two generations of financial technologies and build something as monumental as China's Great Wall and America's interstate highways," Wadhwa said in his op-ed titled 'What the US can learn from India's move toward a cashless society'.
"There is no technology barrier to prevent a UPI from working in the US. Transfers would happen within seconds, even faster than the 10 minutes that a bitcoin transaction takes," he said.
The top Indian-American expert also praised another Indian innovation India Stack, which is a series of secured and connected systems that allow people to store and share personal data such as addresses, bank statements, medical records, employment records and tax filings, and it enables the digital signing of documents.
"We are not ready to become a cashless society, but there are many lessons that Silicon Valley and the US can learn from the developing world," said Wadhwa who is Distinguished Fellow and professor at Carnegie Mellon University Engineering at Silicon Valley and a director of research at Center for Entrepreneurship and Research Commercialization at Duke.
