Can I back up my Biometric Wallet with the R3covery Card?
No. The R3covery Card is a backup card exclusively for the DCENT S (card-type) wallet, so you cannot back up or recover a Biometric Wallet with the R3covery Card.
In other words, the R3covery Card is used to store the private key generated on the DCENT S, so please use it only for backing up and recovering the DCENT S card.
