Every PINVENTOR art piece is unique, handmade and multiple forgery-safe and secured by:
Without the right PIN it is not possible to submit a request for authenticity check !
IF art-work-number, PIN, certificate of authenticity and the pictures done and sent by the owner correspond to PINVENTOR database, the owner receives as a re-confirmation a signed letter by the artist.
For this purpose you need to make a close up picture of the sticker which will be compared with original pictures in the secured PINVENTOR database. Only then you get a personal answer and a confirmation of authencity.
How it works:
Every object in our daily use has a certain pattern - even if it is microscopic. This pattern is usally randombly arranged. e.g. scratches. It is physically impossible to copy every tiny roughness, or scratch on a surface. See examples bellow.
You will always find voluntary made scratches on PINVENTOR art work - especially arround the authenticy sticker.
Modern smartphone cameras are perfect to make highly detailed pictures to send in.
