has that but with a device of their own

Yeah I first learnt about this type of thing with this video about a similar thing in the Netherlands, which they got 3 or 4 years before we got the app version here in Australia.

And apparently part of the reason they're deprecating it is that they're switching from an app version to a "device of their own" version...except unlike the handheld device shown in that video, it's a big tablet that they'll have built into some shopping trolleys. So no luck if you're doing a quick small shop with a handheld basket, or even just carrying it in your arms.
