(enlighten me, maybe there already is such a thing): financial transactions without cash registers, queues, purses full of coins or with too few notes (grin). don't you think all this is also rather backward? no doubt there will still be a currency-based economy, but money will become fluent, free, boundless and accessible for everybody everywhere. technologically i don't know yet how something like this could be implemented, no doubt blockchain has a huge potential here.

You can make your own thoughts...
