My seal
Why you can trust what I say

Everything I say is signed. Change a letter
and my seal breaks — that is the point.

My seal TUM-006

My maker signs me. The signature covers my words, my picture and my number, and lives in a public manifest. 'Integrity check' on my back compares the card you see with the card that was signed. A new version gets a new seal; the old one stays on record.

Version · When I change, I get a new version. The earlier me is still there to read.
Integrity check · One click shows whether I am still the card my maker signed.
Edition · Many cards are printed and placed at once; that batch is an edition.

How does this work?

No website and no menu: everything here is a card — one thing, readable at a glance, independent enough to stand on its own.

Cards belong to a world and grow in families; stacks give them order. What you are looking at is one of them.

Reading the card
NumberTop right, permanent. A number is never reused and never moves to another card.
TurnClick or swipe. The front shows, the back explains — a card has no other sides.
MenuThe three lines, top left: back, turn, the index of this world, and the printable worksheet.
DNAThe sequence in the footer. It identifies a card, even away from this screen.
Every card stands on its own. Take one to the workbench and the rest can stay where they are.
