Before you agree to buy

  • You know the recent sold price for that model and condition
  • You have photos of the real item, including labels, codes and any flaws
  • The seller has explained where and when they bought it
  • You have seen the receipt, box or papers if the seller says they have them
Before you pay: proof and details

Check before money changes hands

Run a VerifAI check on the seller's photos, or on the listing, before you pay. If a Deep VerifAI certificate already exists, ask for its link: anyone can open it without an account.

Pay in a way that protects you

  • Use the marketplace's own checkout and buyer protection whenever you can
  • Credit cards and payment services with buyer protection give you a way to dispute a charge
  • Avoid bank transfers, cash in advance, gift cards, crypto and “friends and family” payments to people you do not know

Pressure is a warning sign

A seller who insists on a payment method without protection, or rushes you to pay before you have seen proof, is a serious red flag.

Meeting in person

  • Meet in a busy public place, or at a shop or authenticator if possible
  • Bring a friend, and good light, and take your time
  • Compare the item with the photos and the serial numbers you were sent
  • Only pay once you are happy with what you have seen

When the item arrives

  1. 1Film yourself opening the parcel, so you have a record if something is wrong
  2. 2Compare the item with the listing photos and serials straight away
  3. 3Run a check on your own photos of the item
  4. 4If something is wrong, contact the seller and the platform quickly; most protection schemes have time limits
Unbox and check straight away

Know what a check is

A VerifAI result is an AI opinion based on the photos you provide, with the evidence behind it. It is not a physical inspection, a guarantee or insurance. For a high-value item, use it together with the seller's documents, the platform's protection and, if you are still unsure, a professional authenticator.
