    At perhaps 2KB per page, you'd need 524288 pages to store a 1GB. That's 1048 reams. Please just use an archival optical disk instead.

    Even if the scheme using multiple QR codes in sequence rather than a single large code block. The paper backup implementations that use QR codes https://github.com/intra2net/paperbackup https://github.com/cyphar/paperback are only meant to be used for private key backup.

  • paperbackup
