For transfer of secret data you could use - dare I suggest it - a wire. :-)
If I must, but most users are too lazy to do that everytime it's actually necessary.

A couple of questions. What's the best way to buy bitcoin? Where do the experienced dopers hang out on this forum? I found Silk Road and I need a few tips.
First tip, don't mention SR. Ever. Second, the best way to buy bitcoin depends upon who you are and where you live.

I imagine the problem will only get worse as bitcoin becomes more popular. It's a bit worrying for the future of bitcoin. Will the cumulative burden eventually overwhelm even hi-spec dedicated bitcoin servers?
Yes and no. Eventually running a full client is going to be like drinking from a firehose, but only professional miners, wallet services, banks, etc are going to bother. Most people will be using thin clients that don't maintain a complete blockchain that is dependent upon a central server to tell it what transactions are important. Much like BitcoinSpinner on Android or Electrum works now.

I looked up bitdex, and there wasn't even that much there from my perspective. I'm sure that you know whether or not a product exists with bitdex, but I don't. You don't even have a video or the attempt at a faq, just a cartoon of a book.
BitDex is the codename. I highly doubt you would find anything online about it, since I've only mentioned it maybe 7 times briefly on the forums since 2011. The discussions related to the BitDex have mostly been done inside the DCAO away from prying eyes. I'm quite curious as to what cartoon you found lol http://bitdex.net/Fair enough, texting is an unnecessary function. Still, they would work great for sending the device a cryptographicly signed purchase receipt, something that I would find useful. You could buy something at wal-mart with bitcoin anonymously, but walk out of the store with a return receipt that's far better than the paper receipts available now. Of course, if you are using a wal-mart branded bitcoincard, they know who you are anyway.
I will say that as a kid I did love those bluetooth, radio and IR connected chatting devices. Something like "My Diary" or somewhatnot. Rad stuff that was. you do realise those where toys right?

I wish gas where I live was under $4/gal. I live in a small town that has 1 gas station and price gouging here is ridiculous. The owner of the gas station has another one in a town with 3 gas stations and the prices are 5 cents cheaper per gallon.
In summary, gas station in my town with no competitor= $4.079/gal gas station next town over (6 miles away) with competitors=$4.029/gal Same gas, same delivery truck.
You do realise that's a price difference of about 1.25% right? I often see larger price differences from one block to the next and from morning to night at the same station. Dude, you're not getting gouged. If he actually has a monopoly at one station in the area, you're very lucky the price difference isn't 50 cents per gallon.

This so explains your hostility to features claimed in bitcoincard, you're biased because you're invested into a competitor.
My hostility is towards vaporware and unsubstantiated claims. No demos, no word on functionality, just a video, some hype-ful tweets, etc. I looked up bitdex, and there wasn't even that much there from my perspective. I'm sure that you know whether or not a product exists with bitdex, but I don't. You don't even have a video or the attempt at a faq, just a cartoon of a book. If this actually works, I'll be the first to celebrate and congratulate the developers. Seriously. The problem is that I don't believe ad-hoc is a solution for Bitcoin transactions, and they have no working prototype to show (the one at the conference wasn't a working demo).
Ad-hoc meshing may or may not be a solution, but that also depends on what your persectives on what the problem is. Wireless mesh networking has it's place, but I won't claim that it's easy or likely, but a meshable hardware wallet would be a useful feature for some. Furthermore, you don't have a working demo either; at least not one you are willing to show us. Will your product be able to transact without cell service
Yes, although we're working with cell companies to have the option available for whomever wants it. How then, if not some kind of p2p ad-hoc connection? If it involves a cable, you've already lost. send free text messages as well?
No. I don't personally see any value of a financial tool being a chatting device. If we wanted that, we'd just stick with using a mobile phone. Fair enough, texting is an unnecessary function. Still, they would work great for sending the device a cryptographicly signed purchase receipt, something that I would find useful. You could buy something at wal-mart with bitcoin anonymously, but walk out of the store with a return receipt that's far better than the paper receipts available now. Of course, if you are using a wal-mart branded bitcoincard, they know who you are anyway.

I'm gonna call that a yes. I'm not. I'd call it a fail, or at least a dodge. I asked if he could prove that those afore mentioned criminal activities have occurred. It was a loaded question, of course, because the only way that he could prove any such thing would be to have access to the private computers of those afore mentioned criminals. Which, most likely, would mean that those computers belong to himself or someone he personally knows quite well. Anyone who would use a publicly posted bitcoin address to send funds to a publicly known criminal either doesn't know the criminal part & didn't buy criminal services or is an idiot, and it would be hard enough just to prove one or the other, much less an actual crime.

Well, I guess no one is willing to sell me a preconfigured router then.. oh well... Ill give someone else my bitcoins... Preconfigured is a different requirement than doesn't require linux.

bitcoin *is* a local currency. It's the currency of a niche of nerdy crypto-anarchists so far.
You forgot drug dealers, human traffickers, and assassins. can you prove that?

And what is BitDex?
Also Matthew, what's the BitDex? The first thing that came to my mind when I read that was PokeDex...
Hehe. Exactly. Think Pokedex, but for Bitcoin (and a lot smaller, sleeker, and it doesn't talk to you everytime something happens). BitDex is just a codename. We aren't releasing the real name until the product is ready for production for obvious reasons. We were working on "Bitcoincard" long before Bitcoincard was working on Bitcoincard for Bitcoin. We're almost ready to present but I have to say, I don't see Bitcoincard as being much of a competitor. Ad-hoc is interesting and all, but it's not practical for the kind of features you'd need in a bitcoin wallet device. We're going full retard with Bitdex though. (Unfortunately, it will need to be charged unlike the black magic bitcoincard, but perhaps when such a technology actually exists to charge the device constantly, we'll release an upgrade) This so explains your hostility to features claimed in bitcoincard, you're biased because you're invested into a competitor. I'm glad to hear that there are more than one option on the way, but I will wait until there is something to see. Will your product be able to transact without cell service & send free text messages as well?

@MoonShadow how about using orbot to start from somewhere ? You made some very good points there but with enough time solutions will come to fill the gaps. Sure, you could use a bitcoin client that exclusively uses Tor to hide your transactions, but you still can't be certain that the phone company doesn't already know what your addresses are. Android clients are going to continue to be a huge part of the bitcoin economy, this is true. However, so will stand-alone hardware devices like this one. We seem to have a bunch of naysayers on this forum with little real knowledge about digital telemetry repeatedly declaring either 'un-possible!' or 'no one would want one'. I want one. Hell, I want six for my family, and I'd start to give them to family members for presents instead of gift cards. Can you see a future wherein a teenage daughter says, "Dad, can I borrow your keys and your smartphone? I'm going to the mal- *cough* library." or "Dad, can I borrow your car keys and a few bitcoin for my card?..." Then you'll love BitDex. And what is BitDex?

providing someone can walk me through making it work without using linux.
that's a practical impossibility. Windows RT router anyone? LOL good luck with that.

Sorry, I do not understand this. Why is this better than a smartphone? A clumsy little card? Why?
you dont get a bill every month you're anonymous when using it ... Using bitcoin with a smartphone wouldn't cost any extra with internet usage included in your contract unless you were charged for extra usage and went over the usage limits. There is also wifi. Not everyone uses smartphones, or ever will. My wife uses a cell phone that can make phone calls and text, and nothing more. I have a android. I've noticed myself that for the act of making actual voice phone calls, her's is superior even though my is three times the cost. Plus, there is the issue of security, your cell phone could potentially get hacked or malwared. A simple standalone hardware device that uses a data protocol that doesn't permit arbitrary code to be loaded onto it from the radio is more secure by nature, thus better for the common user. Better even for the power user in many cases as well. Could you implement some anonymity for smart-phones? Some way to hide the IP address if you every really had to for whatever reason. Is this something people really want?
Yes, some people will want it. No, you can't practially do this with a smartphone, because no matter what you do, your cell phone company knows who you are, where you are, and what packets cross their network. It's smaller It's cheaper A lot of people already use smart-phones, especially people tech-savvy enough to be using bitcoin (I would guess the majority of bitcoin users would have smart-phones but I could be wrong). This would only be beneficial for those that do not have smart-phones and don't want them. It would at that, and that is a market bitcoin needs to be able to penetrate with reasonable & inherent security. I own a smartphone, and I'd buy this card today (and a dongle for my home router) if it were available. I can think of no other method that is as secure from infultration, as portable and as convient. Sure, my cell can text just fine, but not anonymously and not if I'm out camping beyond my providers reach. If I had one of these cards for each of my kids, whether they had bitcoin or not, I could communicate with them even when they were hidden by the trees, so long as they were in radio range with me and/or their siblings. It's more secure (presumably moreso than a smartphone) Well if smart-phones are in risk of malware that could manipulate any bitcoin software. Do smartphones have many vulnerabilities? I seem to remember one smartphone had a vulnerability hackers were taking advantage off which was fixed. I forgot about that now so if anyone is more aware please tell me. Smartphones are just computers. Android is a version of gnu/linux, as an example. Linux is fairly secure by nature, but it's not perfect. The problem is the shear complexity of the modern OS, which leaves open the possibility that a security hole was missed by the developers to be found by hackers in the future. There is also the problem of your cell provder, do you trust them enough to handle your money? Becuase from a practical perspective, they have acces to your unrooted cell phone; so somewhere there is a backdoor to the device. This is how they can update your phone's software over-the-air without your personal involvement. What happens if the next wallet stealing trogen is written by the former developer for Sprint?

The 2m band the cards operate on have much better propagation effects than the bands mobile phones operate on. Thats not my point. Im going by their claimed performance. They say 100-300m, and Ive generously been using 300m. Are you saying in reality its 3Km? I think that you got that from me. I said, if this card is based upon Dash7, a line of sight range of 2km is possible. At least it's possible with a true line of sight and the owner holding the card above his head like shown in the video. Also you are missing the point this is not just about BTC users and there will be LOTS of stationary nodes too once the likes of Wall-Mart, Tesco and most other chains start issuing them as store/loyalty cards.
That is my point. Its not going to be bitcoin users paying for these cards and creating a mesh. If this ever takes off, it will be those kinds of companies creating the infrastructure and giving out those cards for free. So?

Bottom line folks, advertising this as a stand-alone device but in reality requiring the operation of another physical node is downright retarded.
It's neither 'retarded' nor deceptive. The video advertises 'no supporting infrastructure' with a collapsing cell tower in the background. Although it's not technically true, since a usb dongle attached to the back of a POS terminal or internet router is 'supporting infrastructure', the reality is that it doesn't depend upon commercial communications infrastructure. It can mesh to extend it's practical communications ranges, although that's much more likely to involve privately owned dongles and the internet than not. Still, your cell phone can't mesh at all, unless you have a rooted android phone with a running Serval client, and even then can't mesh more than 70 meters with no obstacles. (I should know, I have actually done this) If your city has a power outage, your cell towers' batteries die in three or less hours. So not only can't you make a regular phone call, even though your cell phone is fine, you can't spend bitcoin with the guy standing next to you. With a device that's capable of directly communicating with other devices sans infrastructure support would at least open up the possibility of bitcoin business transactions in meatspace where internet access is not a given. Someone is going to do this, and if done well, the radio standard is going to stick, and more capable devices are going to come into existance that can act like a bitcoincard, a bitcoincard server, etc.

Whats your call sign ?
That would permanently break my forum autonomy, so I'm going to decline.

Another way of looking at it. Assume the maximum stated range of 300m. Assume perfect spreading. 30000 bitcoin users would be able to cover 51x51 Km. Out of a total of 510 million square Km of land mass. Funny that. Edit. Not sure where I got the 30K from. It seems to be closer to 5K: http://bitcoinstatus.rowit.co.uk/serversStart.pngSO all bitcoin users combined could theoretically cover 21x21Km. More realistically, only a fraction of that, barely enough to cover the small town I live in. Surely this would be the relevant chart? http://bitcoinstatus.rowit.co.uk/hostsStart.pngYours is listening hosts, ie those with open ports I think. Anyway, surely we have more users than last September (60,000), most probably can't be bothered to keep th chain up to date anymore. We could have a lot more running clients than that, since some of us have 'quite' clients, myself included, that won't show up in those scans. Those are usually based upon the ip addresses that show up in the bitcoin IRC bootstrapping channels, and there are many clients now that don't use those channels anymore.

Even if every bitcoin user in the world bought one, chances of being able to connect to the adhoc network would still be.. ~zero.
Thank you for your unsupported layman's opinion. As for those of us who actually know a thing or two about radio telemetry & propagation, we've been providing actual facts on this kind of device for longer than most of you in this thread have even known what a bitcoin was. EDIT: I've literally bounced a 2 watt signal off the F level of the ionosphere and was heard over 200 miles away from my position; and actual line-of-sight distance of at least 350 miles up and down. Granted, that was with some high quality gear that wouldn't fit in my wallet to save my life; but for someone who's only experiences with low-power digital telemetry involves the wifi scanner app on his smartphone to tell me it-just can't-be-done is offensive. QRT For the win! You work skip a lot ? Are you working in the 11 metre band ? The sun is near maximum, a lot happening on skywave proprogation If your using 2 watts though, Im guessing your lower mhz than the 11 metre band ? 40 meters, just after dark. No I don't do it often, and intentionally skipping in the CB band is illegal. I have a ham radio license.
