I have met some IoT entrepreneurs, for example, who have worked on creating wireless IoT toothbrushes. I am thinking that Iota could be perfect for ordering replacements with the simple click of a button. Perhaps the toothbrush could have some charging station, and you can easily order replacement toothpaste, floss, etc. very quickly and efficiently.
How does the IOTA tokens fit into this? Why are they needed for ordering replacements? Devices can connect to internet and order stuff without any tokens.
For a general overview of some of the use-cases for IOTA in IoT
read this articleAs for ordering replacements, the payment processing fees are quite detrimental to micro-purchases. If you are to buy something that cost 1 dollar and have to pay a 50 cent payment processing fee, well that sucks.
If I order something to my home now there are no such payment processing fees. If such a scenario actually happens, the fees would come from delivery costs I would imagine? And the store would probably buffer my purchases until they have enough to justify the delivery costs and then I could pay with my debit or credit card like I do with any other purchase/order. Or if they can actually deliver 1 dollar items one by one using a drone or w/e they could send me a bill or charge my card once a month.
The toothbrush doing the actual paying the user would have to buy tokens from somewhere using fiat and a payment processor anyway, and then keep the toothbrush loaded with enough tokens. And what if the device loses its memory or explodes you'll lose your unused tokens.
