The biggest disadvantage I see is that while we think some of this tech will be around forever, I can see a future where all USB ports on PCs are USB C and the NFC standards on phones have changed and someone trying to cash one out has to jump through a lot hoops to do it.

Yeah... But honestly, chip card tech is here since many years (about 40 years I guess) and will be there for a very long time. Maybe longer than the NFC tech.
But that's a good concern. People shoud carefuly check the hardware used in such devices and prefer open source solution that might be easier to move on another tech.

Satochip is proud to release its new product: Satodime.
The bearer chip card that allows you to exchange crypto assets like any banknote. Safely pass it along multiple times thanks the secure chip, unseal anytime with ease. Trustless, easy to verify and completly secure.

I see that price for Satodime is the same as for regular Satochip card, and I am not a fan of Opendime by Coinkite but I believe they are cheaper to purchase.
Bitcoin Crypto Banknotes are a good idea, especially in the time when they announce removal of cash money, but banknotes should be dirt chip to buy in my opinion, they should even be easy to make as DIY project.

One question for Satodime, what secure element are you using for this Satodime card, same chip NXP J3H145 and J3R110 like for Satochip, or something else?

Hello,
Yeah, I def recon on you regarding the price. Satochip HQ fights everyday to be able to offer affordable security solutions.
Regarding Opendime, you have to break it to recover the private key. Meaning you "lost" your device after each use. With Satodime, you can safely re-use your card by resetting an unsealed vault.

Yes, we do use the same chip as our hardware wallet Satochip.

By the way, Satodime is also open source, meaning you can just buy a blank compatible javacard and create your own Satodime - be your own bank.

The OpenDime is $50 for a 3 pack so it is cheaper. It's advantage is it just needs USB, no app no special hardware.

Yeah, there's definitely a price advantage with the Opendime, and I don't see the need to "break open" the device as a major disadvantage necessarily (though it certainly would be better if you didn't have to). I'm also curious as to why dkbit98 doesn't like Opendimes; I think they're kind of neat, although now I realize they're not so great for long-term storage.

I do like the idea of things like this, but still see it as a limited market. I will probably get one, I have gotten just about every other thing like this over time to play with.

It's times like these when I see neat crypto-related tech that I wish I had more money to blow, because I might be interested in one of these if only as a collectible. I also think the concept of a crypto banknote is a good one, but I agree with dkbit98 that the cost of the banknote itself ought to be less. At the same time I do realize that when such banknotes are as fancy as the one OP is selling, they're not going to be dirt cheap.

That's why one of these would be a great collectible. I'd love to own some of the old computers and storage drives I used to have, simply for the nostalgia and history behind them. Since I already have all the hardware wallets I'll ever need, I wouldn't use a Satodime to store any coins on.

And since OP brought up the Tangem (which I'd never heard of), does anyone know if they're legit? I'm not trying to go off-topic, but on Amazon, I see this and scratch my head:

The Satodime is more, but does have NFC and a more standard, and probably more durable design.

I do like the idea of things like this, but still see it as a limited market. I will probably get one, I have gotten just about every other thing like this over time to play with.

The biggest disadvantage I see is that while we think some of this tech will be around forever, I can see a future where all USB ports on PCs are USB C and the NFC standards on phones have changed and someone trying to cash one out has to jump through a lot hoops to do it.

As an example:
I have a REALLY nice set of noise cancelling bluetooth 1.0 headphones that are 20 years old and still working today. (back when Sony still made good stuff) Except for the fact that most BT 4.x and newer devices will not talk to them due to the lack of security. I can still connect them to an 2004 XP laptop but that is about all I can find.....
If I have 0.01 on one of these and BTC goes to $250000 in 10 years, if I have to spend hours hunting down some old equipment, will I bother for $2500 or let it sit longer if I don't need the money?
