Every item gets a unique QR code, with photo, hash, and timestamp captured the moment it's packed.
One final photo of the open box with every item inside — required before it's sealed.
On delivery, the customer scans the QR and confirms they got exactly what was promised.
An AI-assisted report compares the photos and helps you decide with proof, not guesswork.
Compares the QR code's position against fixed points on the product (seam, logo, edge) and flags shifting, removal, or re-application — calibrated so normal wear never gets mistaken for tampering. It's deterministic and auditable: the same pair of photos always returns the same result, which matters the moment it becomes evidence in a dispute.
Compares the packing photo against the problem photo and writes a clear report for both you and your customer. This is the layer that handles what needs judgment — damage, wear, context.
A visible QR label is placed on an appropriate external area of the product. Its position becomes part of the visual evidence, while the customer can remove it before normal use.
3S prepares a PDF with the order timeline, visual records, hashes and the AI-assisted analysis. The report supports your review and platform submissions without promising an automatic outcome.




of customers never buy again after a single bad delivery — even when it's the carrier's fault, not yours.
abandon their cart over shipping costs that only show up at the last second, at checkout.
buy more when returns are easy — but easy returns are also an open door for fraud.
Start with a 10-item pilot, no card required. Paid plans grow with the number of physical items supervised.
No app-store download needed. 3S works directly in your browser, on mobile or desktop — same link and login on every device. You can add a home-screen shortcut for convenience, but there's nothing to install.
Shopify is tested. During the pilot, stores from other marketplaces can start through assisted CSV onboarding while their direct connectors are developed and validated.
Each plan includes a monthly volume of supervised physical items. The pilot includes 10 items without a card. Paid checkout and overage rules will be shown before billing is activated.
No. The AI report is a suggestion to speed up your review — the final decision (accept, deny, exchange, refund) is always yours.
3S is being designed with GDPR and other applicable privacy requirements in mind. Retention periods, service providers and safeguards are documented in the Privacy Policy and will be finalized before paid public launch.
No — just the label printer you already use (Zebra, Argox, Elgin, Tomate, Phomemo) and a phone or tablet with a camera. No new hardware required.
