Tangem Wallet: Cost and Security of the Card

The Tangem Wallet is a hardware wallet in the format of a bank card, and it works without a battery, without a cable and, in the standard case, without a seed phrase. The two-card set costs 59.90 euros, the three-card set 69.90 euros. The private key is generated inside the card's chip and never leaves it. The backup runs through a second and a third card that carry the same key. Both the great advantage of this design and its biggest risk follow from exactly that.

For you as an investor in Germany, this is a trade-off between two sources of error. With a classic hardware wallet the seed phrase is the weak point: anyone who photographs it, types it into the cloud or stores it carelessly loses their holdings. With the card wallet that sheet of paper does not exist in the first place, but everything then hangs on the cards themselves. This article weighs the two models against each other, gives the documented prices and certifications, and says where the limits lie.

What the Tangem Wallet is: card, NFC chip and the Tangem app

A hardware wallet is a device that keeps your private keys offline and signs transactions without handing the key over to the computer or the smartphone. The Tangem Wallet does that job in a form factor closer to a debit card than to a USB stick.
