Theft & security

• Mirrors/cameras on blind spots — cheapest measure
• Expensive goods near checkout or behind glass
• RFID/EAS tags on high-risk items
• Return control: receipt + act, CCTV on checkout zone
• Weekly count of fast SKUs — catches shortages early
• Seller liability + cash discrepancy tracking
• Anonymous staff channel — exposes internal schemes

Retail shrinkage structure: ~50% internal staff theft, ~35% shoppers, ~15% accounting/supplier errors. Grocery shrinkage is 1–2% of turnover; electronics up to 3–4%. Measures pay off if cost < saved losses.
