Specialized applications are used to create paper wallets. These applications generate a private key which you need to provide in order to prove ownership and spend bitcoin.

A QR code may also be embedded in the paper wallet to make it easier to scan and sign to complete a purchase. It is recommended that you use any paper wallet generator offline to prevent hackers from discovering the private key.

Test your computer or phone with security software. This will help you determine if it has been compromised by malware or other cyberattacks.

Some paper wallet generators let you store private and public keys as PDF files on your computer. This is not recommended, as PDFs can be vulnerable to online threats.

To prevent hackers from finding your wallets, avoid scanning them or taking digital pictures.

Switch off Bluetooth and Wireless on your device. Hackers can access your device using these signals. You should take additional precautions to better protect any money in paper wallets.
