Printed Electronics - the Big Picture

Cash is a matter of trillions too. The US, UK and Japan, taken together, handle two trillion dollars in cash transactions every year. Cards with printed logic and antennas will be cheap enough to manufacture and use to replace most of that, with billions of people holding them for convenience and cost reduction. Some will subsume the card in their RFID enabled mobile phone which will become paper thin and even disposable thanks to printed electronics.
