The security seal can be removed in advance to check the existing private key. It can then be covered again with the provided protective sticker.
The private key should only be read by the Chainlock card’s user and in a safe surrounding. The private key provides access to all cryptocurrency amounts linked to the card.
A broken security seal (“seal broken”) is a sign that a manipulation has occurred.
Anyone comes into possession of this card can very easy remove security seal and see private key, so this is much less secure then any hardware or desktop wallet. This is actually a cold wallet, and it is safe only if users is store it as they say
"Secure storage at any secure place (private safe or safe deposit box in a bank)"https://chainlock.com/?lang=enSo, from my understanding, the crypto card/wallet has a seal on the wallet where when peeled off reveals the private keys? If this is the case, there's no point of using it really. Too susceptible to theft, and if that's the case, I doubt the company would be naive enough to give the card a credit card use. You'll basically be bringing a crypto credit around that if got lost, you'd lose all your money.
Also looks like the way to deposit/withdraw your crypto would be exposing the private key? That's not very safe - I've also attached a photo of what it looks like according to the site.
"Key generation in high-security zone: the generation procedure, for which a patent application has been filed, ensures that nobody can view the key pair – not even YOUNIQX staff."
Even worse. What's the point in buying hardware wallet if you're giving the company all your details?
Discharging the Chainlock card
Expose the private key beneath the security seal / protective sticker.
Scan the private key as a QR code (or, alternatively, enter it manually) using your preferred digital wallet.
Load the cryptocurrency from the Chainlock card into your digital wallet.
This is a pretty big letdown. More risky to use then a ledger/trezor, and no extra features (multi-currencies, etc).
