The activists also took out an "Aabhar" march from the temple to Dr Bhimrao Ambedkar's statue at Jhandewalan, expressing their gratitude for naming of the app after the father of the Indian Constitution.
Modi had, during the launch of Bharat Interface for Money (BHIM) app on December 30, had drawn parallels between the app and Ambedkar's contribution to uplift the downtrodden.
The Morcha activists and party leaders - including Tiwari and New Delhi MP Meenakshi Lekhi - garlanded Ambedkar's statue riding a crane.
"Naming the multi-purpose mobile banking app as BHIM is very appropriate. The app operated with the help of thumb impression will prove to be the foundation for a new India," he said.
BHIM is a simplified payment platform designed to make Unified Payment Interface (UPI) and USSD payment modes simpler and usable across feature phones and smart phones.
