What does claiming mean in the context of crypto stamps?

Once you have received your physical stamp, you can claim its digital twin on the Ciphers.me platform.

You can scan the QR-code or manually enter the publicID of the physical stamp and then add your stamp in the collection with the claim code.

Now you will see the stamp digital image in your collection and it’s added to your account.

Please note that this stamp is now claimed, but it isn’t an NFT yet.
For this you need to mint your stamp.
