By the way how much would cost a single bitcoin banknote would be?
Does is have some sort of technology that it could connect to the internet and sync it's value to the current market?
The cost of Tangem Notes does not currently depend on denominations, although we might consider additional security mechanisms for very high value ones like 1 BTC. Currently we only ship 0.01 BTC and 0.05 BTC.
The Notes are always denominated in crypto, they don't need to be synced an app can show their current market value.
I was think of this the past few weeks , OMG I can not believe that there is someone actually working on this , That is just amazing . The idea is so close to what was in my mind but I am not sure if it is similar . What was in my mind is to make this Banknote process a decentralized process so anyone in the world can just scan his BTC and use it
Haha, the idea was there from the start of Bitcoin, I think, but it was really impossible to implement. The best the community could come up with was Opendime, which is great, but not user friendly and not as secure as I would like. Tangem Notes are made possible only with the latest advances in secure microelectronics in 2017, which finally caught up with blockchain and became powerful and energy efficient enough to perform Elliptic Curve Cryptography on an NFC chip.
Tangem Notes are completely decentralized, and can be used physically or digitally.
I have not thought about this: bitcoin paper money. When does that happen? If bitcoin is printed on paper money, it must be issued by the State and regulated in a stable manner.
The BTC is electronically stored on each Tangem Note, so there's zero need for any centralization or protective regulation. It's all made safe with state-of-the-art cryptographic mechanisms.
