Whilst the convenience of credit cards mean that payment disruption in developed markets may occur at a snail's pace, some believe that the absence of widespread debit/credit card usage will lead markets such as India to 'leapfrog' towards mobile based payment platforms. 

The creation of the so-called 'India stack', whereby the government has played a key role in creating digital finance infrastructure (much of it through opening API's to its own services, but also by creating entirely new networks) is not just applicable to India, but could serve as a global template for the revolution of financial services if it succeeds. 

This view appears to follow the maxim that 'this time is different', as previous efforts at banking digitization have been painfully slow in a country where cash remains king.
