Woolworths in Australia has a solution called Scan and Go. You use the app on your phone to scan barcodes as you take things off the shelves. When you’re done, the app charges your stored credit card and you scan a qr receipt at the door as you leave which opens a little boom gate. I believe there’s still some AI based visual monitoring in place but it’s much simpler. Instead of needing to identify exactly what you’re picking up, it just needs to flag when it thinks you might have picked something up without scanning it. If that happens, it triggers a staff member to come have look in your bags when you scan your receipt to leave. It seems like a much more pragmatic way to realise 80% of the value you get with “just walk out”.
