The public and private keys of a bitcoin address are physically printed on a piece of paper to create a paper wallet. These keys are frequently shown alongside their corresponding alphanumeric strings as QR codes.
An individual who creates a paper wallet can receive cryptocurrency transactions by giving out their address to others. Both manually entering the keys and using a smartphone to scan the QR codes can be used to complete transactions.
Users can generate fresh addresses and keys when offline with some paper wallet providers. Users must download the wallet generator as an HTML file and run it off the internet in order to accomplish this.
