A hardware wallet keeps your seed inside. CardSigner saves it to a card and then forgets it. Create your seed on CardSigner and save it to a PIN-locked Satochip SeedKeeper card. Unplug it: the seed is gone from the device, and the card keeps it.

Your wallet creates a transaction. CardSigner scans it and signs it.
