[ContemplationInTranquility]

I agree with everyone about the Orwellian overtones to this but also what if there is some kind of natural disaster that stops these devices from working such as a hurricane. What good is your smartphone or whatever then. I personally use cash all the time. I don't buy anything on the Internet these days except train and plane tickets. Support your local shops because they are disappearing at a rapid rate. I haven't bought anything from Amazon for the last 5 years since I found out the terrible effect they were having on other businesses and the awful way in which they treat their workers.There's nothing cool about paying by card or a mobile device, however you pay it's just a means to an end not an end in itself.
