The number of recovery attempts for the Backup Card is set to 10. This number refers to the "password entry attempt count" for the backup image.
When you create a backup image of the All-in-One Card Wallet, you need to set a password. This password is a 4-8 digit password consisting of English alphabets and numbers that encrypts the data in the backup image.
Therefore, you can try entering the password for the backup image up to 10 times. If you succeed in entering the password and complete the recovery, the private key stored on that Backup Card can no longer be recovered, so the message "This card has already been recovered" will be displayed.
Please refer to the following user guides for backing up and recovering your All-in-One Card Wallet:
Go to the Backup Guide >>
Go to the Recovery Guide >>
By the way, there is a way to check if the Backup Card you have has already been recovered. The method is to select the "Manager tab > Scan new card" menu and tag the Backup Card. Then, check if the wallet address displayed in "My Wallet" is the same as the original All-in-One Card.
