Method and system for assigning ownership of a marked physical item involving track and trace

A code attribution control system, comprising

• a code resource of unique codes, wherein each said code is arranged for being placed or marked openly accessible legible or scannable on one or more sales items;
• and
• a track and trace system arranged for tracking and tracing each single item individually in a logistical supply chain,
• wherein the items' codes are scanned and/or registered by the track and trace system when the items are received/delivered and supplied to a shop, whereby the code of said item is registered in said track and trace system to be stocked by the shop,
• wherein said one or more sales items are arranged for being openly and freely displayed and for sale within a physical border of the physical shop,
• wherein each said code marked items initially are allocated a status code attribute as “not sold” in said attribution control system,
• wherein, for a consumer in possession of said code marked item and at a position outside said border, to establish ownership or indication of ownership of said item, the consumer scans and registers said code to an attribution control system from said position outside said border of the shop,
• whereby said status code attribute is changed to “sold” in said attribution control system, and
• whereby ownership of the code marked item is associated to a consumer identity is registered in the control attribute system, after which owner restricted services related to said code marked item will be made available to the consumer.
