Convenience created a loophole

Self-checkouts cut queue times but, as UK loss-prevention analysis shows, they also create unmonitored gaps that contribute heavily to shrink — a theme echoed daily by frustrated staff and shoppers on UK retail forums.

The four most common scan-avoidance tactics

1. The pass-around — moving an item past the scanner without a beep.
2. Banana trick — ringing a premium item as a cheap loose product.
3. Partial scan — scanning one of several identical items.
4. Walk-off — abandoning the transaction after bagging.

How vision-AI closes the gap

De Flow AI’s visual recognition compares what the camera sees in the bagging area against the items the till actually registered. A mismatch triggers a discreet real-time alert to a roaming colleague — catching the loss without falsely accusing honest customers or grinding throughput to a halt.

Why it beats locking everything down

Shutting self-checkouts or guarding every lane erodes the efficiency they were installed for. AI keeps lanes open and intervenes only on genuine exceptions — protecting both margin and the customer experience.
