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

Would purchase at least two. What a wonderful way of 're-investing' into BTC's future with your earnings.

Cheers,

If this is a cute way of publishing your public address as a way to receive BTC then it is cute, maybe even classy.

If it is supposed to be a way to send money, then it is useless (or at least insecure). If the private key is printed on it (as a set of numbers or QR code or whatever) then all I have to do to steal the BTC is look at it, maybe even from a distance. I can use a camera with a telephoto lens and take a picture of you holding your card. As soon as I do this I can spend your BTC.

If you give me one of these as payments for something, I have to run the transaction then and there to make sure the BTC hasn't already been spent. It is not a way to perform a BTC transaction offline. It is not a way to securely hold BTC.

I suppose you can take the private card and keep it out of sight (literally), but why put it on a wallet size card if you aren't going to carry it around?
