But what happens when there is a major disaster? How will people pay if there is no internet/electricity etc.? At least with cash you can plan ahead...also what are the poor people to do?
Cash hasn't been banned in India. Only ₹500 and ₹1000 denomination currency notes have been scrapped. Replacement currency notes (₹₹500 and ₹2000) with new design are being disbursed at banks and ATMs. It would take few more days to stabilize, that's all.
