Plotting the next Fintech revolution in India

When was the last time I used my debit card? 

I can't even remember. In most cases

 I will either swipe my credit card or use the UPI app on my phone to make a payment. 

The most remarkable aspect of this discussion is not the fact

 that more and more of us are giving up our debit cards

but rather the fact that the technology that is being developed to replace them is being built in India for the benefit of the entire world.

UPI recently expanded its operations across international borders and launched

early adoption pilots in the United Kingdom.
