The RBI's recent consultation paper regarding the possible revision of charges on digital transactions -- including UPI -- has become controversial. Many users were unhappy and took to social media to express their disappointment. The Centre, too, isn't happy. The Finance Ministry tweeted that UPI is a digital public good and that "there is no consideration in Govt to levy any charges for UPI services."

Also, can we now assume that the plan to levy a charge on UPI payments has been dropped?  Hamsini Karthik helps understand the issue better. Listen in.
