Certificate system

Limited, consecutively numbered, publicly verifiable. A short explanation of what it is — and what it is not.
Numbered per product
Every piece sold gets a consecutive number. Counting happens per product: “No. 37 of 50” refers to that one product, not to the shop as a whole. Once an edition is exhausted, no further number is issued for that product.
The redemption code in the parcel
Each piece comes with a one-time redemption code, included in the parcel. It lets you link the piece to an account on this site — once; a code that has been redeemed cannot be redeemed again.
Redeeming is optional. The number and the edition size are fixed regardless.
Public verification
Product and number can be verified publicly. The verification shows product, number, edition size, issue date and whether the piece has already been redeemed.
It shows no personal data: no name, no order number, no address.
What it is not
Nothing about it is signed. The pieces go straight from production into shipping — nobody handles them for that purpose.
It is not a security and not an investment. No increase in value is suggested. The code evidences number and edition size — nothing more.
