Unauthorized Entry / Tailgating

Shoppers should be informed to watch out for anyone entering the store unauthorized while they're entering or leaving the store. They should make sure to close the door after them so that the other shopper validates on entrance – otherwise, products taken by the second shopper may be on their receipt.
On the other hand, shoppers should be informed that the system reports any unauthorized entry so that any shoplifting attempt triggers an alert in real time (starting from OASIS 4.6).
