trade safely.

Meet in a busy place, such as a train station, ideally during the day. For expensive items, bring someone along. Inspect the item carefully before you pay.

Cash or TWINT — once the item is in your hands. Never pay strangers in advance, and never pay with gift cards or money-transfer services.

The most common scam: someone "buys" your item and sends you a link — supposedly from Swiss Post, TWINT or öppis — to "receive the money". It is always a scam. To receive money you never need to enter card details, codes or passwords.

We only write from an @oppis.ch address and never ask for card details, codes or passwords. A sign-in link only arrives if you requested it yourself.

People who want to switch to WhatsApp or e-mail straight away often want to avoid leaving a trail. In the öppis chat everything stays traceable — and after the deal you can leave a review there.

• Price far below the usual
• Seller "currently abroad", shipping only
• Pressure: "today only", "others are interested"
• Advance payment only
• Excuses instead of real photos

For vehicles, check the registration document and service book and compare the name with the seller's. For phones and laptops: is the device signed out of iCloud or Google? Ask for a receipt — a short sales contract is enough.

Report the listing with its link to kontakt@oppis.ch. If you have been defrauded, file a report with the cantonal police. Help and information: cybercrimepolice.ch and the Federal Office for Cybersecurity (NCSC).
