Your idea is great. As a first step, the digitilization may be restricted to high denomination currency. All transactions above an upper limit may be Rs.1000/- could be brought under this mode to protect transactions within the village or rural India. All transactions in large shopping malls shall be brought under the digital net, monitored by the government. Our own greed and the desire to outsmart our neighbour is the basic cause which perpetuate corruption in our society. Joy Jacob
