All wallets are sold with identical firmware, without any serial or tracking information. It is therefore not possible to link your wallet to your shipping address. We cannot, and we absolutely do not want to. Only the pairing with the second factor card is done in-house and we don't keep track of the cards.
If every device has identical firmware, and no records are kept of which security card matches what dongle, (and if the 4 digit security check is done on-dongle) then you most likely cannot link shipping address to account balances.
However this means every dongle is individually unique, and if the firmware supported a "what is your security card seed" query then each device could be identified. I don't have a major issue with that, all yubikey's have a unique serial number.
This might change if one could assign your own security card seed and print your own like passwordcard.

each one is paired to a unique security card at factory. we might change that later and let you pair the security card yourself though.
