This reminds me of another tool that does a similar thing but on a wireless network, it's attack is officially called packet hijacking or something.
But anyways, accessing a CDN or Public DNS server would be quite the pull off. One of them going rouge basically would never happen as well.

Hi folks
First of all NEVER hesitate to contact us by email or via the support whenever you come across something like this. While we are trying to be on top of these kinds of things we may miss some of them. Anyway we are now working on making sure that this domain will be deactivated ASAP.
Cheers
Good to see you guys getting on top of it right away ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) As for the email, I always make sure I see the text version. It would point these little tricks out. Additional Info: - The real website is " http://w5xhdezxlz.tmweb.ru/". - Uses a PHP POST request. - Redirects to the legitimate login site.

There is no need for stamped letters. The stamped letters on credit cards are legacy from earlier days of credit cards. Today most debit cards in europe (Visa Electron and Maestro) have only imprinted numbers.
There is no need for extra items on Bitcoin cards, only the magstripe is needed. They can be very cheap in bulk. In opposite to credit cards, Bitcoin cards have no need to be protected by card design and hidden UV texts and similar. You can forge a fake credit card, but You can't make a fake Bitcoin.
And how much info needs to be stored on the cards? Will they fit into ISO specified tracks?
I wouldn't think it would be too much. I've forgotten the format since last week when I looked at it, but Wikipedia always helps ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) . I looked and it seemed that the ISO/IEC 7813 standard would work: Track 1
The Track 1 structure is specified as:
STX : Start sentinel "%" FC : Format code "B" (The format described here. Format "A" is reserved for proprietary use.) PAN : Primary Account Number, up to 19 digits FS : Separator "^" NM : Name, 2 to 26 characters (including separators, where appropriate, between surname, first name etc.) FS : Separator "^" ED : Expiration data, 4 digits or "^" SC : Service code, 3 digits or "^" DD : Discretionary data, balance of characters ETX : End sentinel "?" LRC : Longitudinal redundancy check, calculated according to ISO/IEC 7811-2
The maximum record length is 79 alphanumeric characters. Track 2
The Track 2 structure is specified as:
STX : Start sentinel ";" PAN : Primary Account Number, up to 19 digits, as defined in ISO/IEC 7812-1 FS : Separator "=" ED : Expiration date, YYMM or "=" if not present SC : Service code, 3 digits or "=" if not present DD : Discretionary data, balance of available digits ETX : End sentinel "?" LRC : Longitudinal redundancy check, calculated according to ISO/IEC 7811-2
The maximum record length is 40 numeric digits. Of course it would need to be changed, so here's what I thought: Track 1
The Track 1 structure is specified as:
STX : Start sentinel "%" FC : Format code "B" (The format described here. Format "A" is reserved for proprietary use.) PAN : 0000000000000000000 (Translation account number, where the service would convert this to the actual place to take from) FS : Separator "^" NM : DarK Stealth (The card holder for ID checks) FS : Separator "^" ED : ^ (None, this card should last a life time) SC : ^ (No service code) DD : Discretionary data, balance of characters ETX : End sentinel "?" LRC : Longitudinal redundancy check, calculated according to ISO/IEC 7811-2
The maximum record length is 79 alphanumeric characters. Track 2
The Track 2 structure is specified as:
STX : Start sentinel ";" PAN : 0000000000000000000 (Translation account number, where the service would convert this to the actual place to take from) FS : Separator "=" ED : = (None, this card should last a life time) SC : = (None, this card should last a life time) DD : Discretionary data, balance of available digits ETX : End sentinel "?" LRC : Longitudinal redundancy check, calculated according to ISO/IEC 7811-2
The maximum record length is 40 numeric digits. Thinking about it, we could really just have a magnetic stripe, as it would be cheaper.

I could see this going somewhere, as I made this: https://bitcointalk.org/index.php?topic=54057.msg644784#msg644784. The problem with RFID tags you can't just say, no you can't read my card now. It can always be read unless you like sticking a sheet of metal in pocket or wallet. I'm not sure if this is still going, but I'd be willing to help with this, not rage and be a dick like someone in this thread.

What does the card do? How does it work? Can you give us a simple use case? Is it a "Pay Me" card that just has my public information on it so others can pay me or are you trying to figure out a way to use it to pay others and buy things with it (like the current fiat money denominated credit and debit cards)?
What is your vision here?
I think people have found valid solutions to pay with bitcoins, but not a perfected. QR codes have finally got more popular up here in Canada, but there are a few flaws with them. - The camera needs to be decent, which tends to be on smartphones - A "app" needs to be developed to pay with bitcoins which can be a little security hazard - The QR code has to be big enough but small enough so it's easy to scan - The "app" needs to made well to read the QR codes, I've used a few on Windows Mobile, one was great and the rest failed to even the code in the same environment. - QR codes seem to be a "work around" solution if you get what I mean. My vision is that you would be able to go to any store and this happens: Cashier: "How do you want to pay for this?" You: "Bitcoins please" Cashier: "Sure, just swipe your card." Being able to do it would make BTC very popular, it would have some of the lowest fees in history, and almost everyone would be able to take them. The setup costs, and usage costs would also be much lower. The only real problem is the initial investment for the cards. I mean the real ones, signature panel, stamped numbers and magnetic strip. Costs about $200+ USD for about 50 I think. Someone may come along and say "OMG! HE'S GOING TO MESS THE WHOLE MARKET UP!" - This is not my point. Someone will have to do the payments, and I want to stay away from those dirty banks ![Wink](https://bitcointalk.org/Smileys/default/wink.gif) . A simple program that I could design and make would perform all the tasks to transfer bitcoins for almost no fee (and side note, I'm working on a pay/transfer via url thing as well, eg. btc:\\pay\myaddress). This is where I'd like to see bitcoins go, because right now they are only practical for internet usage, and a one off smartphone transfer via QR code. Magnetic swipe cards would be fast and easy. We could even go to RFID tags, but it's another attack surface I think it would be fairly reasonable to avoid.

Frickin' nice! Very nice! Personally, I'm having trouble getting my head wrapped around the term 'Credit Card'. Perhaps a different word or term for what you have here is in order. Hopefully the community can help me (us) out with this issue I'm having.
I've been referring to these as "Pay Me" cards, since they basically perform the exact opposite duty of a credit card. (Probably not the best term, but I sort of copied that from a sci-fi TV show I was watching that referred to ID as a Show Me card.) Instead of being used to give money, you use them to receive a payment. Hand your card to someone, he scans it with a mobile device, and then transfers coins to your account. You could do the same with a cell phone generated QR code, but a card eliminates the need to hand a potential stranger your valuable and rather personal mobile device. The concept of pulling funds from an account, as is done with basically all modern banking and credit cards, is one of the most fundamental ways the entire banking system is flawed. It will take a little change in thinking to get used to this reversal in how funds are transferred, but we'll all be much better off in the end. By the way, I can have your card printed for you at www.paymyaddress.com. I do also offer a 20% commission on sales from contributed designs. So far, the best sellers have been my original design and design #5 (the one with the Casascius coin background). Sure I'd be happy to submit some designs. Is there something different I should change or add? I'd like to get with that whole "credit" or "debit" card idea, but it seems like a costly investment. I thought of adding a barcode for POS systems, but I'll see what you think.

As posted in another thread: I can submit my design from here.Is there anything else that needs to be done?

Just something I did when I was board. A sort of credit card design I made. Includes a SHA512 hash and a MD5 hash which I know. Not done, but I'll work on it. If you feel like donating, please see my signature.

Yea, it would seem to be a power issue your having there.

If you think your wallet may be compromised by a coin stealer virus or something, generate a new address and send your remaining coins there. You can make an instant paper wallet here: https://www.bitaddress.org/ Do it on another computer if you can, print it out, and just send your coins to the public address. What software version are you running? Two things that could be happening: - As they pointed out above, could be a wallet stealler that has somehow got on too your computer. Might of been via USB (which is very common these days)? Rootkit wallet steallers could be possible, but it isn't likely. - Your still catching up with the blocks. I can't explain the deductions your seeing from "today".

Take a look at the link in my sig if your wondering why.

I'll add a little more gasoline if I may, to celebrate my 5th hour. ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) The reason is that they are supposedly partnered with ATI/AMD. You will never see this commercially used popular (and I'm surprised a project like this even existed). PhysX is used in almost every major game, and those that don't, use Havoc (which is CPU). 2) Quote If it wasn't on the card, you would have to do the calculations on the CPU Of course if i don't use the card i use the CPU. The problem is, physx is made to run well on nvidia card. But it's not the only engine around As answered above, PhysX: A) The best B) The most popular C) Commercially backed, with Major's like VaLve. D) It's GPU based, using a PPU. 3)Please explain me where i am wrong, nvidia did not invent physics engine in gaming. "precompute"? Lolwut, it was possible to do the same thing that physx do before physx was created. Of course they didn't. Who said that where? Idk if you are all into game mechanics, or developing (it seems not), games had to precompute (process long before, mainly stored in a file or memory saying what should happen) physics and thus was quite limited. As far as I remember, you would not be able to drive vehicles like you can do now. Anyways, it would seem I am free. ![Cheesy](https://bitcointalk.org/Smileys/default/cheesy.gif)

No one wants a DOTA 2 guest pass for 9 bitcoins? Price is negotiable, just message me if you want it!! ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) I don't have bitcoins, but I'd give you Canadian Dollars for it. ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) Stupid pool not paying out yet :|

There is about $9 Trillion of M2(cash plus money in savings,checking and small CDs) money in the USA. So with simple some simple math
$9,000,000 Million / BTC 21 Million(total bitcoin ever to be mined) ~= $428,000 / BTC
So if bitcoin replaced all of US dollars, 1 Bitcoin would have the same buying power as $428,000 does right now.
If Bitcoin replaced 1% of US dollars as a currency, 1 Bitcoin would have the same buying power as $4,280 does right now.
Something to think about.
Yea even at it's "current" value of about $2, that's twice as powerful then most currencies in the whole world.

A signed integer can be either negative or positive (- or +), such as 55 and -55. An unsigned int can only be positive. If you only need to deal with positive numbers, you should use unsigned ints because the maximum integer number the type can hold will be twice as much as a signed int.
Correct. We could get into the amount of values it can hold, but that maybe a little more advanced (like a 64 bit unsigned integer).

He he, I'm almost safe from the stupidity it seems when you mix the internet with governments - except in the case with Bell and the CRTC.

There will be a flaw found sometime in the future, it's just natural for that to happen. Would it cause and end? I don't think it will. As mining becomes to hard, or in how many years (seems to be structured towards 2015 I think) you can't mine anymore, people will move to transaction fees. While this is going on, it's going to get quite popular, so more and more people will use it. Really, it won't have a sudden cliff drop "stop", it may just slowly die out - after all, BitCoins are an experiment. ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif)

3. AMD/ATI cards are cheaper. It's less costly to setup the miner then with nVidia cards. I posted on here that ATI/AMD cards probably have less quality. Just google "ATI loud fan". Should i link exploding nvidia cards? ![Roll Eyes](https://bitcointalk.org/Smileys/default/rolleyes.gif) I think your talking about defective cards. If that's the case, It's been identified and fixed. A brand new ATI card has a VERY loud fan problem, I just can't seem to find the video I watched a month ago. PhysX is used for PHYSICS calculations. Here's a nice block for all of you to read: Wow so much yaddayadda I'm giving a straight answer that's correct. Where's your answer huh? Before PhysX, game designers had to “precompute” how an object would behave in reaction to an event. Bullshit. [/quote] I don't think your knowledgeable in that area sir/madam. It is quite well known, just take a search before you raise the alarms... On top of that, I don't think nVidea would lie like that. Think about it next time before you say things. ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) PhysX is designed specifically for hardware acceleration by powerful processors with hundreds of processing cores. Let me rewrite: PhysX is designed specifically to run on nvidia cards. I wonder why, maybe because uh it's nvidia propietary code? And lol at games using it. Yeah, to add like what, 2 particle? [/quote] No, it does make a difference. If it wasn't on the card, you would have to do the calculations on the CPU - and I hope your an expert on such things as it seems like your saying you are. Take a look at games that use PhysX. Fluid dynamics is one such area you will need the GPU to do calculations. There are other physics engine that run on all systems instead of nvidia only.
Ah, your talking about Havoc and such. Those are all CPU based, but lack a lot of "realism" to what they can do. Source games are a wonderful example. ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif)

No i don't store my passwords in that type of file, nor do I believe I even used that credit card with this computer,I think the incident was probably unrelated. Would anyone agree?
I would 100%.
