Actually I was wondering about the possible risks of someone using a device to try to access the funds within the ring itself at a distance. I believe it is already something which happens to holders of NFC credit cards, alledgedly, because I have seen some wallets which advertise themselves as a protection against thieves who seek to exploit such attempts of stealing money.
It would be still a unlikely scenario, but not impossible if we are just talking about a NFC chip embedded in a ring, it would be "safer" if there was some actual "smart" technology within the ring or used an interface linked to our smartphones to sign transactions: it could be a combination of NFC and the typical biometric security which is already offered by most of Iphone and Android devices, using a fragmented private key (like Shamir) between the phone and the ring, so the funds would be safe regardless of the loss of any of them.

Just some random ideas about this product, in the end, those developers could come up with something even more intelligent than relying security on biometric data on the phone.

The NFC in the ring is linked to the wallet in your phone. You need to open the app, authenticate (pin / biometrics), create the transaction, then tap the ring to your phone to verify that it's really you and you want to do this transaction.

You can't recreate¹ the wallet with just 1 ring / card and you cant send from the wallet without the ring / card.

¹ With the original way there was no seed phrase that you could see / recover your wallet with. Their new app allows that.

"Confiscation" doesn't necessarily have to be legal. Hispo says this here:

Quote from: Hispo on August 11, 2024, 01:56:11 PM

... all of it is just in order for the person to get scared and give their Satoshis to the officers.

I have a few concerns. One of them being,

The United States are particularly known for very strict Airport regulations and Security. If big companies like Samsung start rolling out 'Smart Rings' and maybe some of them look similar to the Tangem Ring, what happens if I am an innocent citizen going through the Airport Security procedures and on the day of my arrival the Airport Staff is on alert for a possible Terrorist trying to enter the United States? I presume this means verifying Smart phones, which they already do according to my knowledge, together with laptops, Hard Drives et cetera. With Smart Rings becoming trendy and obviously a technology, would this not put my Tangem Ring at risk?

Also. Can longer distance NFC detectors be integrated in the Airport filters? As in once I pass through a gate, which is pretty close to the body anyway, they know I have a smart device on my body. This could also be a problem if the detection technology allows for it.

It's not a 'smart' ring. It's an NFC chip embedded in a ring. No different then the NFC chip in your credit card or similar.

I would not go so far as calling it an experiment. Not to put too fine a point on it but (at least here in the US) people have been micro-chipping their pets for years. So it's not like it's new. While traveling it's probably going to be fun to explain what that thing is in your hand to airport security if you do have one implanted.

Putting microchips (and other experimental liquids) in human bodies IS experimenting, and I don't care if it's coming from Elon Musk in form of his brain chips, or from someone who is using it for identification and payment.
I know that one group of lunatics think that we are just animals for them, but I really don't care if someone is putting microchips in dogs and cats as preparation for doing the same thing with humans.
This is not related to Tangem Ring, so let's get back on topic.

A reason for a thorough search may even be a suspicion of the possibility of being a possible criminal on the run or not quite. If desired, these employees can easily find any reason for a private conversation with you, during which it is easy to find any crypto wallet.

In addition to that, the ring alone isn't going to be enough to access their funds ^{[e.g. they need the access code as well]}.

The availability of the access code is also beyond doubt, since it is obtained through psychological or physical pressure, depending on the degree to which the authorities in a given country comply with the laws.

Nobody in airports or port of entry in other countries used to pay attention to others wearing black or white rings, as soon this becomes a trend within the whole of gadgets and technology, I am quite sure authorities in those places will start to pay attention to them and even ask for people to give them to them for a while, so they can verify there is nothing illegal stored in them or something.

Then perhaps I am being a little bit too much paranoid then, probably because I live in a country which is very corrupted and airport officers would not doubt much if they noticed someone carrying a hardware wallet in order for them to interrogate that person and probably accuse them of money laundering or terrorism, all of it is just in order for the person to get scared and give their Satoshis to the officers. It has happened before, but with other kinds of assets, like gold rings and cash.
I have got a friend how moved to Chile and he witnesses how a military woman almost managed to steal a loaf of cash from one of the passengers who was going together with him, in the last minute the cash appeared, because the consulate representative was pressuring the officers to seek for the money.
One of the reasons people are likely to hide their cash when fleeing this place.

I believe it is quite an interesting Idea, but instead of going all in and using a ring to confirm and sign transactions of Bitcoin and other cryptocurrencies, it would be more constructive to use these kinds of devices as methods of online authentication (together with our phones). I am also honestly worried on whether this kinds of devices could be targeted by thieves as others have expressed in this thread.

I would personally I would not dare to wear more in my finger, beyond a couple of dollars to pay for a coffee using Litecoin, Monero, or other fast-to-move alternative coins.

However, contrary to Tangem Ring, those stuff that are "just normal things" are not stabbed (constantly) at smartphone. Thus, I still believe that persons with wallet in the ring form-factor can be easyly spotted and tracked.

You have a point, but I don't think it'd make sense to use it in a public space because of the fact that in order to make it work, we have to remove it from our fingers first ^{[even with a privacy screen protector on our phones, it'll surely attract a lot of attention (especially by snatchers)]}.

Hm, I suppose you don't wear such stuff.

My wife lost three of them, very expensive gold ones, one even with diamond. I myself have lost my ring , just misplaced it but not remembering where.

People commonly take them off when take a bath. Besides, wearing ring for a long time results in the dermal irritation thus you are bound to take it off.

People will lost them, Tangem Ring including.

There are already manufacturers in China who are making ring devices like this, so I guess they just made a deal to make them custom device with Ring logo.
Even with two added cards in package I think that it is not worth that much money for this.
Little bird told me that open source alternative ring wallet will come out soon and it's going to be cheaper than $160.

The Tangem Ring is functionally the same as the new Tangem Wallet cards, except for its different form factor.

Considering that it doesn't bring anything new to the table while it's almost triple the price of the two Tangem Wallet cards ^{[or double the price, if we remove the two backup cards from the equation]}, it doesn't make sense for Tangem users to upgrade to this HW ^{[especially since the only way to get it to work is by removing the ring from our fingers]}!

For those who might be interested, the thebitcoinhole's promo code for Tangem Wallets also works for this ^{[it'll be $144]}.

Now that Samsung is making their own Smart Rings that will most likely become pretty main stream, what is your opinion on wearing the Tangem Ring? Is it a good thing that Smart Rings are becoming more popular for Tangem owners or is it not?

I am kind of skeptical for a few reasons. One being that once Samsung Rings become more widely known and used, wearing a dark ring on your fingers could trigger specific negative Events. Authorities seizing it from you, getting it checked and or seized at the Airport or even becoming the target of thieves.

I have seen people with dark rings on their fingers before, but I never thought of it as an expensive item. Pretty much the opposite instead, as it looks like a regular metal or stone ring. The launch of Smart Rings could change this.

Even if you pay for Ring wallet now they won't be able to send them to customers for months, they plan to start shipping in the end of October, and that usually means in November or December.

The $160 price is a ring + 2 cards so more or less it's one of their 3 card sets but one of the cards is in a different format.

What I can't stand are these partnerships HW wallet manufacturers enter into (Ledger went way overboard with that), and even some software wallets like Trust have done it as well.

I don't like it either, but I understand why they do it from a business perspective. Why have the users move the funds they want to exchange from the hardware wallet and into a third-party exchange if we can create the same type of service and have them do it on our terms? Plus, we earn a small commission from it. I also don't buy the marketing hype of how it's cheaper than doing the swap directly through the 3rd-party exchange.

I am not even going to comment on the bad reputation that Changelly has. It only takes a minute to find several threads and discussions on Bitcointalk that discuss that.

Yeah, I even made a complaint thread about them a few years ago, but in the end I didn't get scammed. Changelly has been around for a long time and I thought that they were at least fairly reputable even if there have been some scam accusations against them. I don't think that's too far off-topic--and yes, I did read SFR10's post.

What I can't stand are these partnerships HW wallet manufacturers enter into (Ledger went way overboard with that), and even some software wallets like Trust have done it as well. It sort of feels like the evolution of Google, where once upon a time it was a simple search engine and was excellent in carrying out its purpose. And now? You search for something and the only thing you get 90% of the time is advertising thrown at you. If I'm looking to buy a HW wallet, I just want a device to keep my coins safe and I don't want constant reminders that the manufacturer is in cahoots with various services of varying reputation and is pushing me to use those services.

It feels fakkin' icky, you know?

But instant exchanges, like Changelly, have never been famous for their low fees or excellent exchange rates. People use them for quick swaps between two crypto assets, knowing and expecting that they will get a bit less than doing the exchange manually in a normal crypto exchange. That's why they are ok with paying a bit more in fees.

Actually, there is a worry - you could get robbed, or held at gunpoint and be forced to hand over your jewelry. Sure, the crooks will not the least suspect that your ring is actually a hardware wallet storing thousands of dollars worth of crypto (but then again, why are you carrying it on your hand everywhere in the first place?), but it will be, at best, a hassle to recover your coins, and, at worst, a crypto theft.

I am not a fan of the idea either. But hey, you don't have to wear it all the time like your wedding ring. Put it on when you intend to use it and take it off when you are back home. Not all jewelry that people wear is valuable. Some people wear friendship bracelets or bracelets their kids made for them. It's not worth a cent and may look bad, but had sentimental value.

Good for swallowing up if something goes wrong (let's say, at a border crossing) or for places where the stuff hiding is a primary concern (let's say for those who are jailed).

Unless this hardware wallet ring becomes immediately conspicuous for anyone looking at it longer than a second, I wouldn't worry about it. People own various pieces of jewelry that they wear and cross international borders with all the time without any problems. If you get jailed, you'll have your valuables, such as jewelry taken from you by the officers, to be returned upon your release.

Actually, there is a worry - you could get robbed, or held at gunpoint and be forced to hand over your jewelry. Sure, the crooks will not the least suspect that your ring is actually a hardware wallet storing thousands of dollars worth of crypto (but then again, why are you carrying it on your hand everywhere in the first place?), but it will be, at best, a hassle to recover your coins, and, at worst, a crypto theft.

Rob the old fashioned way and take away this wonderful ring. Or you'll just take it off somewhere and lose it. Like a banal ordinary ring. Carrying such a wallet with you is completely unreasonable, but only if the balance of this wallet contains only small change for pocket expenses, like buying coffee and a donut with chocolate glaze. Wouldn't it be a little expensive for such a wallet?

There is one more point: this device works through a smartphone application and an installed application and doesn't have physical buttons for confirming outgoing transactions as on traditional hardware wallets, which is protection against online theft. How will this ring be protected?

Good for swallowing up if something goes wrong (let's say, at a border crossing) or for places where the stuff hiding is a primary concern (let's say for those who are jailed).

Unless this hardware wallet ring becomes immediately conspicuous for anyone looking at it longer than a second, I wouldn't worry about it. People own various pieces of jewelry that they wear and cross international borders with all the time without any problems. If you get jailed, you'll have your valuables, such as jewelry taken from you by the officers, to be returned upon your release.

Actually, there is a worry - you could get robbed, or held at gunpoint and be forced to hand over your jewelry. Sure, the crooks will not the least suspect that your ring is actually a hardware wallet storing thousands of dollars worth of crypto (but then again, why are you carrying it on your hand everywhere in the first place?), but it will be, at best, a hassle to recover your coins, and, at worst, a crypto theft.

Material mentioned in video is zirconium dioxide, I don't think that is ceramic, it's more like a metal.

I am not sure. At around 2:00 in the video, the guy mentions that Zirconium Dioxide is a ceramic material.

If you google "zirconium dioxide ceramic", the first result is a Wikipedia source that states: "Zirconium dioxide is one of the most studied ceramic materials." At the same time, if you ask google, "is zirconium dioxide a metal", it tells you "Zirconium dioxide, also known as zirconia and zirconium oxide, is a crystalline metal oxide that has found its way into the ceramics industry."

Zirconium Dioxide is a ceramic material and has been used in luxury watches like Omega's all-black Dark Side of the Moon Speedmaster.

Nice find.
I don't like how glossy Tangem Ring looks right now, but IP68 is not bad, maybe you can take a short swim with your hardware wallet.
I saw on Tangem twitter account they gifted all 100 Tangem Ring prototype wallets to visitors in cardano summit , this was not a bad marketing move from Tangem.

I shouldn't be surprised if something similar and designed exclusively for rectal use would appear.

There is an interesting business model. Perhaps a hardware wallet worn on your manhood or a vibrating one for the kinky crypto enthusiasts.

This is a wallet or just a signing device ..who knows.. no technical specs so far.

According to it, the ring will have a secure element and be NFC compatible. Everything will work with a native app, since the ring has no screen. The security features include PIN codes and biometric authentication. The ring doesn't have a battery, so it will be interesting to see what powers it. Backup cards will work if you break your ring, it gets stolen, or you lose it.

The ring is made of a ceramic material and is water-resistant.
Apparently, it's not going to hit the market before Q1 2024.

It saddens me that so many new entrants are pushing blind signing (without a screen). It feels like a major regression in security model. I would have hoped that the industry had learned from Ledger's first Nano device a decade ago (screen-less), but it seems like new entrants are repeating the mistakes of the past.

As much as I despise ledger, I have to say they probably earned most money from all hardware wallets with their promotional propaganda.
Most people don't care about security if they have something popular that looks nice from outside Tongue

That being said, let's wait and see how Tangem Ring will actually work.

Quote from: SFR10 on November 03, 2023, 03:21:00 AM

They'd probably offer it in two/three sizes.

I hope this won't be a new trend.
Imagine someone purchasing Tangem Ring, and than they have to return it and replace with different size.
Bad security written all over it.

Quote from: m2017 on November 03, 2023, 09:50:47 AM

The world will probably see even stranger devices.

Probably, but I won't accept body injectable hardware wallet or anything like that, and we are going in that direction Tongue

First I thought it was some kind of joke, but than I received confirmation from several source, and I see some preview images.

Well, it looks quite nice. Today the technical details of this HW device will be known. We wait. It will be interesting to know how it all works.

Quote from: dkbit98 on November 02, 2023, 04:04:21 PM

First thing on my mind was about sizing, because you can't have universal one-size-fits-all, fir different fingers.

If this is ~~Lord of the~~ Tangem Rings, then the size of the ring doesn't matter - wear it around your neck on a chain. Wink

Well, right, why? Implant the chip, which is located in a ring, directly into your palm and welcome to the era of new digital assets.

We know that Tangem Ring will be released on November 3, at Cardano Shitcoin Summit this year, in Dubai, but there is no information about it on Tangem official website.

Great name for a summit.

Design-wise, it reminded me of the Bitcoin Bolt Ring, and even if it comes with a lot of features, I think it'd suffer the same fate as the one I mentioned earlier ^{[e.g. little to no success]}.

Judging from their tagline of trust-based choice (they also claim the random-based private key generation would make the wallet safe), I wouldn't be surprised. They claim to offer many new things for crypto with flexibility and fashion as one of its focus. I don't think that's even necessary for a HW. I guess they don't intend to target security-aware people in the first place? If that's the case, we can only wait for the news when one of these wallets gets hacked or people lose money from dumb stuff.
