The electronic tags they put on the product is scanned and 'validates' the item as sold along with your card ID if used.
Then the cameras stationed everywhere record your purchase and the ones in the lot record your car as your phone tracks your every move.
If the tag wasn't scanned, the sensor at the door would 'beep' if installed as many did. The security guard would come detain you and/or call the police if determined necessary.
