There are OpenDime devices on the market already, and they recently seem to have developed a new version of their disposable wallet.
Opendime is perhaps closest to Tangem Notes in terms of ideology. Like Ledger, Opendime uses secure electronics in addition to insecure chips. Our goal is to make Tangem Notes by far more secure and easier to use than any other technology on the market.
So, is there any way for the company to retrieve lost cards? Knowing people, they would lose these cards or it will get destroyed. or is this card indestructible?
I can just imagine that millions of these cards will be created and not a lot of them will survive over time. What happens with the odd Satoshi that are on these cards, if the fees to transfer them, are higher than the amount?
