"India's Universal Payments Interface is rapidly becoming one of the world's more prominent payments schemes, with the government promoting its use as a means of luring tourists and speeding cross-border payments. If India's CBDC takes off at home, it too could become a model for other banks around the world"
So, that's the benefit is it? Luring tourists (I'm not quite sure how?) and speedier cross-border payments.
No potential downsides then? No vague indications that it might become programmable? Oh, there is you say. Well, no thanks.
