The Singapore company, Tangem, presented Bitcoin denominations, which the manufacturer calls smart-banknotes.
Bitcoin banknotes are not made from paper. This is, in fact, hardware-encrypted wallets in which the Samsung S3D350A chip is integrated.
At the same time, they have a lot of common features with traditional banknotes. For example, each of the new Bitcoin denominations has a fixed BTC nominal value and can be used for physical payment in stores. Tangem calls his banknotes a "hard-wired hardware that can not be copied".
The manufacturer has announced that the technology used in these banknotes is reliably protected from external interference. All possible attack vectors from both the hardware and the software level were reported. Embedded technologies are used to protect credit and SIM cards and thus have received a product whose hacking is economically unprofitable.
One of the main advantages of these banknotes over online payments is the instant offline payment and the absence of any fees and commissions. But, like traditional banknotes, there is a considerable risk of theft.
For the time being, banknote bills with a value of 0.01 and 0.05 BTC are available. To date, this is about $ 96 and $ 480.
