Even if each card is an NFT on the Ethereum blockchain, visible and tradable on any NFT platform, the content they carry is only visible on one device at a time – making them digital uniques. When you scan the QR code, the content gets re-encrypted and transferred for your device, making you the only authorised viewer in the world. Content becomes unavailable to any previous viewer.
These demo QR codes work for everyone but in real life scenarios only the NFT owner can generate a transfer QR code. For each Personal NFT there is ONE OWNER and ONE VIEWER only. The content is encrypted end-to-end between our servers and your device where it gets decrypted.
