India is forced to subsidize farmers to the tune of $37B JUST for urea. Governments routinely offer free bus services to women, free cash handouts to women, free electricity to farmers (who then use the power to pump out groundwater and grow paddy in areas otherwise not suitable for it). The list goes on.

A $1B subsidy to eliminate friction on the payment front is peanuts.

After whatever maybe 15 years that have banned the practice.

Hopefully they allow foreigners some track to access UPI in the future.

Here in Poland we have a budding "save cash" movement. And they make some good points about freedom and privacy but are the loudest about the processing fees when mostly it's a way for smaller merchants to avoid paying taxes. Which is fine, I think they should be exempted anyway, but let's not pretend that it's the 0.5% in fees rather than the 30% in taxes.
