Paper Wallet

A form of cold storage where a private key for Bitcoin address is printed on a piece of paper (with or without encryption). As such, all traces of the key are removed from the computer where it was generated. Bitcoin wallets need two strings of code; a public key identifying where the bitcoins will be stored and a private key which allows the owner to send those coins to a different address. A paper wallet is a printout of both these numbers either as strings of digits and letters or as QR codes . To redeem bitcoins, a key must be imported in the wallet application so it can sign a transaction. If created properly, paper wallets are considered one of the most secure ways to store cryptocurrencies.
