The surge in cashless transactions since Nov. 8th is not a sign of India moving towards a cashless society. It is merely a sign of merchants making do, while situation the gets better. From what I see, the "situation" has gotten worse and is expected to be that way until the new Rs. 500 notes get into wide circulation.
When I make a cashless transaction these days, I avoid the possibility of long queues at ATMs or banks and perhaps some fringe benefits, aka cashback. But I am also shifting my inconvenience to the merchant with whom I am transacting.The merchant, in turn, could shift their inconvenience to their employees.
