For a savings wallet QR code you could also have it tattooed on.
Since you have to really spend it all once it's been opened, thus rendering the tat non-functional, that would be a good incentive not to spend it!
Why would you have to spend it all once it's been opened? Just tattoo your bitcoin address, then anyone can scan your skin to send money to you! I would do it for safety. I guess it depends what software with what security is available at the time it happens. I like the idea of "one-time" savings wallets that you can send to as often as you want but then only expose the private key once. If you're happy with your crypto-nerd powers then it's probably not necessary, but being a crypto-weeny myself I'll settle for something like Casascius's paper wallet key-pairs, rather than having to deal with the change into a new address and so forth. I don't mind dealing with a small day-to-day spending wallet client on my regular computer, but a savings wallet and arcane (for me) crypto precautions? Nope, sorry. I still don't get it. You'd never have to expose any private keys (beyond having them in your wallet). Just pick an address that your wallet generates, then make a QR code out of it and use that for a tattoo. I think the biggest problem, especially after the recent theft of 25k btc, is that people dont trust their computers, the pairs help because they wont be linked to a computer and so any funds on them are safe until redeemed, I suppose you need to trust I won't hijack it, but I've been in btc for a while and really have no interest in theft and want to see btc take off. I got scammed out of 120 btc when they cost less and really dont want to see that happen. all of the keypairs will be made offline and deleted. True enough. I suppose it's easier to trust a single person than trust that your computer will be safe from hax forever. I do like the metal engraving idea, I just think it might be too expensive for most people. But I'm anxious to see how they turn out.  It really shouldn't cost too much |

Noitev, how much acid were you on when you made your signature?
obviously not enough. Don hertzfeldt is amazing |

I guess you could make QR-code earrings or necklaces or bracelets too. Love the card idea! I'm sure custom anything with a metal or plastic base is possible. |

I have an exciting update in the near future!

I am willing to invest in this if you need financing to buy a large enough order, which would be very justified. Look at Bitbills.
Oh golly, I appreciate the offer, but I had like 320 coins I got when they were very cheap, I'm using that. |

Very neat!
So how exactly do you engrave the metal card?

The picture is just a prototype. The finished product will have 2 cards (One with just the public key so people can send funds to it on the go. and a public private one to stash.) I have a fairly high level of trust on Bitcoin-OTC (I go by noitev on there too.) My engraver that I used my Bitcoins on should be here soon and its a high end engraver. There's also a small possibility of a business card sized usb drive with a public address on it. put your own wallet in it and send me a btc address to put on the front and you have a usb backup you can send coins to on the go.  Big news:
I Work for Bitbills now and im getting the final product ready with him!
Stay tuned! |

That's what salt is for!  Just read it up on Wikipedia... Uhm, I think you need to read up on it. Salting helps defend against table lookups but does not strongly protect against brute force. if you put enough salt in a md5, itll take thousands of years until you can crack it, ive tried |

Im about to drop 5000 dollars on an engraving machine to engrave btc public private key pairs. one with an address and one with a private key (youd get 2 cards). if someone on the street wants to pay you, you give em the public card to scan (or type). put the private 1 in a safe and redeem it when you need to. This would be probably the safest way to store btc since the network will hold it and you need not rely on your computer or any electronic form of storage. you can also easily check the card balance by going to block explorer.
the cards would cost approx $20 in btc. I have a fairly high amount of trust and would make keypairs on a machine disconnected from the internet solely for this purpose. the pairs would be deleted after each one is made and memory wiped frequently with some sort of erasing program that erases rewrites and erases again.

interest? hoping to get the engraving machine next week....

You copied all of the actual bitcoin info from wikipedia anyway, I feel a better method to increase bitcoin notice is to just tweet www.bitcoin.orgTHIS IS A SCAM |
