If you receive a QR code labeled as a "paper wallet" or "private key", you can import it into your RVN Wallet by following these steps: On the main screen, tap on Menu. Under Preferences, tap on Ravencoin Settings. Select Redeem Private Key. Tap on Scan Private Key and scan the QR code on your paper wallet. Any funds stored on the paper wallet/private key will be sent into your RVN Wallet's, and will not remain on the paper wallet/private key. If you want to import a wallet created with the RVN Wallet, use the Unlink from this device function instead. Visit this page for more information.
