At the exit there's always a 'check' but it's pretty farcical.

Hence moving to AI

Once you get to a checkout, hi-tech cameras above the self-checkout machines now track all items being scanned and bagged.

After that, smart gates will lock automatically to prevent anyone with unscanned items leaving the store, sounding an alarm in the process.

Those two points are infuriatingly well rolled out in Australia since that article - if your bagging technique does not match the AI model or the color of your fruit/vegetables does not match the AI model for the thing you choose, even if the weight is correct, it requires a staff member. If any shopper in the self checkout area has violated the AI, nobody is allowed to leave the store until the staff member does their check (it's like those automatic gates you'd see on an office building lobby).
