Fellow Aussie here. Many moons ago, growing up on a pineapple farm, I helped fund my school trip to Japan by gleaning late ripening pineapples that were left after harvesting and sold them in a roadside stall out the front. The money was short a few times, but it generally worked.
I'm now in the vending machine business and I've been brainstorming designs for frankensteining some old parts into a roadside stall automated vending machine. The cryptocurrency aspect would be an interesting alternative. It would be easy enough to print a QR code and display it and no power would be required.
Awesome @brendio. I would love to know how that project unfolds. I guess one of the main considerations with crypto in Australia, is often the internet is not good or non-existent in places and 3G and 4G is the same. But if that is not an issue with the location you are considering, I think it is a fantastic idea. Lovely to hear that a humble pineapple honesty box funded your school trip. Thanks for reading.
