"In 21st century India, there is no place for corruption.
Corruption slows down growth and takes a toll on the dreams of the poor, neo-middle class and middle class," he wrote in an article posted on Linkedin.com.
"Large volumes of liquid cash are a big source of corruption and black money," he said while referring to his "historic" decision on November 8 to scrap Rs 500 and Rs 1000 notes with an aim of ending corruption and black money.
Asserting that in 21st century India, there is no place for corruption, Modi said, "Corruption slows down growth and takes a toll on the dreams of the poor, neo-middle class and middle class."
In this context, he referred to his pitch for cashless transactions.
"I urge all of you, particularly my young friends to lead the change and inspire others to turn towards cashless transactions. This will set the strong foundations of an India where there is no place for corruption and black money," the Prime Minister said.
"Today we live in an era of mobile banking and mobile wallets. Ordering food, buying and selling furniture, ordering a taxi...all of this and lot more is possible through your mobiles. Technology has brought speed and convenience in our lives," he added.
Along with the article, he posted pictorial references to cashless options like credit cards.
"I am sure most of you are using cards and e-wallets regularly but I thought I must share with you ways through which increased cashless transactions are possible," he said.
