That' s funny.I did not realize that Japan was that advanced regarding electronic money.
What about Infox? You know, that small device that they use to charge your credit card in restaurants or taxis...
You only need electricity, a LAN cable and that' s it.
But, let's try to see the mechanisms that underlie this process:
- first you insert your card into the device
- then the system connects to the server to authenticate the identity of the person that owns the card
- and they come to you by saying: "We are going to charge you with that amount. Are you fine with that?
- assuming that you agree, ultimately you sign and the transaction is completed.
What does it mean to put your signature on that small piece of paper? What's the purpose of doing so? Well, it's just to tell them to go ahead and charge. That's it. No more no less.
However, there's a question that still remains in my head: why do they need your approval represented by your written signature to charge the card and to transfer the money from one account to another?
I think it's because they need an entity that is in a way intelligent and that can make a quick decision at one given moment. But bits don't have any intelligence unfortunately. They cannot make that decision. They just "undergo" what the software wanna do.
That reminds me of the notion of computation: the transfer of a piece of information from one register to another. Money is a flow of bits. I already know that. Thanks to Julian for his brilliant insight. (Please refer to his previous post:"In Search of a metaphor for money")
But if you think about it, we are basically building up a gigantic software that controls our behavior everyday. Our brain are the computers. The neurones are the hardware. The software is the set of memes we get everyday.
And our brains need information to run the software. They need information to compute. Otherwise they are useless.
Eureka! That's it. I got it.
Money, as you handle it through coins, notes or currency symbols like USD, is just the human equivalent of the bit for our brains. In order words, a dollar is bit that can be easily handled by the electrochemical computer inside your skull.
