Good finds from down the street.

Bought from a neighbour, seen from every side.

• Scanned on the seller's phone

  The seller turns the item on a sheet of paper while the Mint app films it. Mint builds a 3D model you can turn on any phone, so no side stays hidden.

• A price you can check

  Mint names the item, writes the listing and compares the asking price with what the same thing sells for used. The badge tells you if it is fair.

• Checked again at pickup

  When you meet, scan it again. Mint compares your scan with the seller's, view by view, before any money changes hands.
