What it is

Computer vision models monitor self-checkout stations to identify skip-scanning, product switching, and barcode concealment as they happen. The system runs continuously without additional headcount, improving both detection consistency and staff allocation.

Data you need

Video feeds from self-checkout camera hardware, ideally paired with POS transaction logs for ground-truth labelling and model training.

Required systems

  • ecommerce platform

Why it works

  • Install high-resolution overhead and side-angle cameras specifically calibrated for product and barcode visibility.
  • Integrate POS transaction data to correlate scan events with vision detections for higher-confidence alerts.
  • Establish a clear staff escalation protocol so alerts are acted on quickly without unnecessarily confronting customers.
  • Schedule regular model retraining cycles aligned with seasonal product changes and planogram updates.

How this goes wrong

  • Poor camera placement or low-resolution hardware produces too many false negatives, undermining trust in the system.
  • High false-positive rates lead to customer confrontations, damaging shopper experience and causing staff alert fatigue.
  • Model drift after product range updates causes previously reliable detections to degrade without retraining.
  • GDPR compliance gaps around biometric or persistent video data storage trigger regulatory exposure.

When NOT to do this

Do not deploy this system in small-format stores with fewer than 4 self-checkout lanes, where the shrink volume is too low to justify the setup and ongoing cost.
