German supermarkets have become stricter about suspected shoplifting since the introduction of self-checkout machines. The legal standard for theft (Diebstahl) in Germany requires intent, but supermarkets can detain you for "suspected theft" and involve police regardless. Even innocent mistakes cost time and stress. Understanding the rules protects you.
Self-Checkout Risks
Self-checkouts at Rewe, Edeka, and an increasing number of Aldi locations use cameras that cross-reference items scanned against items placed in the bagging area. Failing to scan an item, scanning the wrong item's barcode, or placing an item in the bag before scanning it can trigger an alert and a staff intervention.
If an error occurs: immediately call staff before leaving the terminal. The typical procedure is to void the transaction and rescan with supervision. Do not leave the self-checkout area with an unresolved discrepancy.
Eating Before Paying
Eating something from the store before paying is legally gray in Germany. Courts have found both ways, but practically: if you eat something and then pay for it at checkout (keeping the wrapper), this is generally accepted. If you eat it and dispose of the wrapper before checkout, you've destroyed evidence of the item and this can be treated as theft.
The safest rule: don't eat anything from the store before you've paid. If you must (medication, blood sugar), keep the packaging visible at checkout and tell the cashier.
Reusable Bags and Personal Items
Bringing in reusable bags, backpacks, or shopping bags is legal. However, carrying your own bag increases scrutiny at self-checkout and sometimes triggers random bag checks. You have the right to refuse a bag check — security cannot legally force you to open your bag. However, refusing may result in the police being called. If your bag is clean, opening it quickly is usually the faster resolution.
Scanning Your Own Items at Self-Checkout
Some stores allow you to scan items with your own device (app-based self-scan). Others don't. Using a phone to scan without explicit permission can appear suspicious. At stores offering this feature (Rewe, some Edeka), the app confirms you're authorized. Don't improvise.
If You're Accused
Stay calm. You have the right to call the police yourself. You do not have to sign any document (confession of shoplifting, Hausverbot notice) without understanding it — request an interpreter if needed. If the store detains you for more than the time needed to verify your purchases, they're exceeding their rights. Your passport or ID is not something you must surrender to store staff — only to police.
If you genuinely made a mistake, say so clearly, show the item, and offer to pay. Most stores prefer this outcome to police involvement for minor amounts.
