Tangem Bitcoin HK Kit

Sale price Price $49.99 Regular price

In the first such collaboration, Tangem partners with the Bitcoin Association of Hong Kong to introduce a limited edition co-branded smart banknote — a special hardware wallet that can be used as cash — handed over to other people for physical transactions.

Tangem Notes are highly secure smart cards carrying cryptocurrencies on a recently developed EAL6+ SecurCore microchip from Samsung Semiconductor. The value can be extracted at any time by signing a transaction from the Tangem Note to an arbitrary Bitcoin wallet. This requires a compatible NFC–enabled Android phone and is protected by a 60–second security delay. 

Private keys cannot be imported or exported from Tangem Notes under any circumstance, they are only known to the chip itself. No backup possible — by design. Each Tangem Note creates its own private keys and can never disclose them. The value is completely tied to the physical chip. Loss, theft, or destruction of a Tangem Note will result in loss of funds.
