Saw the recently implemented smart exit gate at local Coles.
I had few items in my trolley from another store. The gate opened fine.
Next time, just as an experiment I took a potato (cheapest item i could imagine) and did not pay for it, but paid other items. The gate opened fine this time too.
Just wanted to ask here, should I keep the receipts from other stores? As I don't know how the smart gates work, what to do if the gates don't open for some items (bought from another store) which the smart gate machine thinks as stolen? Did anyone face such scenario?
The smart gates use AI to track you from a checkout to the exit but they don't check what you've bought, only that a paid transaction has occurred.
