A smart banknote or paper wallet can be used like a classic banknote; however, the owner can redeem his wallet (physical banknote) and transfer the value to a digital wallet by scanning the QR code with the private key.
A cold wallet is considered to be one of the most secure ways to store Bitcoins and other crypto assets (“coins”). The central element here is the key pair of “public key” and “private key”. Both public and private key are represented by QR codes of which the private one is sealed.
In addition to secure offline storage (cold storage), another advantage is the form of easily transferable, high-quality and durable banknotes/crypto certificates that serve as an offline medium for storing cryptocurrencies and can be used like classic banknotes. A paper wallet can also be stored in a safe or vault, similar to precious metals or cash.
