New Delhi, Mar 23 (IANS): Vijay Shekhar Sharma who created India's largest digital payment service Paytm has a little grudge that he never had a chance to study at Harvard University.

Sharing pictures with Harvard University President Lawrence Bacow at Harvard Center Shanghai on Twitter, the Paytm Founder and CEO was ecstatic.

"Though, I couldn't go to Harvard for formal education. Today, met very inspiring and gracious president of Harvard, Mr. Bacow," Shekhar tweeted late Friday.

The digital payments company recently claimed that it was the largest contributor to the volume of UPI payments in India, recording a growth of 600 per cent in transactions in six months.

The total digital payments market in India is expected to touch $1 trillion over the next five years, according to a recent Credit Suisse report, and Paytm is still leading the race despite several tech giants like WhatsApp ready to launch their their digital payment services in the country.
