I feel like a lot of people miss this point. The technology has existed for years although clearly the cost to implement a touch screen console has also plummeted.Even accounting for that most self-service checkouts are just a tilled turned around.

I wonder how much of this is super markets jumping on to the fact people are conflating automation with using a machine and assuming self-service checkouts are proof of a technological revolution. At the end of the day the same amount of work is being done at the till as if a cashier was working but it is now being done for free and a company won't miss a chance to capitalise on an opportunity like that.
