It's not about tech ; the tech exists already. That wasn't my point. Everyone in the country could have a debit card with contactless payments TODAY if the banks wanted to offer them to everyone. They don't.
Well, it's more than the technical availability I'm talking about. I'm talking about the far reaching 'changes' that happened and are happening in our society and how fast it goes. Especially when everything becomes digital. It certainly wasn't something I could have predicted as a kid.
Do you still buy cd's, dvd's, magazines, newspapers, books? Do you still go to a library? Do you use Facebook and other websites for social interaction, do you chat online, use webcam and so on? I presume your world is quite digital as well. In a broader sence, it's all about computers, automatisation, communication satellites, Internet, fiber optics etc. (read: communication, data and speed). This digital era is bringing some kind of new industrial revolution so to speak, with an entire new economy, and it's happening right under your/our nose. Banks are following that path too.
What you are talking about is a credit card and how some people cannot be trusted with that, but that's only a speck in that whole scheme and frankly said, irrelevant. Banks do have there mechanisms to prevent abuse, but whether it's cash or a card, if bad people want to abuse a system they will abuse a system. It won't stop banks especially when it becomes easier to trace digital transactions. Banks really don't want to go digital?
It's ALREADY digital! They are NOT opposing but stimulating the available options. I can use my cellphone to pay for all kind of stuff, check my accounts or manage my payments online, use my cards to pay wherever and wheneve I want, my earnings are a number on my account, I can use online services like PayPall, etc. I hardly use paper money anymore. People, especially the younger ones, are already more and more comfortable using cards and modern technology so we can expect the use of cash to drop even further in the future. And there will be a point where cash is hardly used anymore.
For the record, I'm not talking about what will happen beyond that point. I do think paper money will disappear eventually, but how this will be achieved is to complex for me to speculate about (gold, inflation, a new digital currency...)
