Responding to a mention made by Samajwadi Party member Jaya Bachchan during the Zero Hour in the House, Mr Prasad also said more than 2 crore people have been trained by common service centres on digital payments.
"The BHIM app has been downloaded by 2 crore people and there has been close to 50 lakh transactions only on the BHIM app worth Rs 1,500 crore," the minister said.
BHIM is an app that allows transactions using Unified Payments Interface (UPI).
Raising the issue, Ms Bachchan while congratulating the government for its intention to move towards digital and cashless payments, said that inadequate infrastructure was hampering digital payments.
She said demonetisation was improperly planned and caused "confusion and hardship" to people in the country. She said there were only 15.1 lakh PoS (Point of Sales) machines in the country, while the requirement was of 20 lakh.
"Lack of digital preparedness is already threatening to hit consumption growth," Ms Bachchan said and supported her contention citing SBI data.
In a surprise move, the government had scrapped high denomentation notes (Rs 500/1000) from November 9, 2016 with an aim to check black money, terror financing and fake currency, among others.
Communist Party of India (Marxist) leader Tapan Kumar Sen spoke about the privatisation of Indian Railways, giving examples of outsourcing of cleaning and maintenance services.
He said foreign companies were being involved in the manufacturing of locomotives, and coaches too were being given to other parties.
Mr Sen also protested against the alleged privatisation of railway stations.
