Crypto stamp is a physical postage stamp that has a "digital twin" in the blockchain. The digital twin is an NFT (non-fungible token) that represents ownership of the physical stamp. The stamp has an NFC (near-field communication) chip that can be read with any NFC-enabled smartphone. By scanning the NFC chip, you can check that your Crypto stamp has not been activated yet. Crypto stamps are issued by authorized postal authorities and come in limited supply. There are currently four versions of Crypto stamp: 1.0, 2.0, 3.0, and 4.0. Each version has a different design and circulation limit. Crypto stamp Collections are virtual stamp albums that can be identified by a name entered in the Ethereum Name System (ENS) . To activate a Crypto stamp, you need to scan the secret phrase code on the back of the stamp using a smartphone camera or enter the secret phrase manually. Once activated, the digital twin is minted on the blockchain and can be traded or collected like any other NFT. Crypto stamps are a new way to combine traditional philately with blockchain technology. They offer collectors a way to own a physical stamp and a digital asset that represents ownership of the physical stamp.
