Pre-paid electricity

There are several immediate impacts: a) it is a huge business for the private sector (more than the mobile phone business);

b) the elimination of human corrupt chains/pickets in the system; and c) clearing the way for introduction of pre-paid cards in gas energy and other sectors for the consumers. (Modernise and quicken the Treasury Challan operation, and payment of government fees and charges; at various points it's too much paperwork and foot pedalling.)

When humans are dishonest, depend on intelligent machines, like computerised systems.
