QR Code Coins

[OneEyedJack]

Would it be in the realm of possibility to create a coin with a qr code on it? Like laser etched?
I am thinking it would be cool to be able to have coins like int he amounts of 5, 10, 20, 50 & 100 with their own individual qr codes.
Then have a wallet that allows me to deposit the amount associated to that coin onto that qr code.
Then you could spend them like cash.

I mean I know there are some things wrong with this like change and what not.

But I just think that paper wallets are easily destroyed, like if you left it in your pants pocket and washed it.
Where as a coin is solid.

Unless they already have these, then forget I said anything

Nice thought, they'd just be a novelty/gift item though I think. For any significant amount you'd have to check the balance of the address which means you'd need a phone/tablet/whatever in which case you might as well just use blockchain.info anyway. There's also the issue that the coin would really need both the address and the private key on it, making it a single use item because you'd never know if the person/people before you kept the private key.

I made these to hand out, they are cheap,
have the value on the back (in the middle of the qr code) and a qr code that links to http://realbitcoin.info/
(my side dedicated to explaining them so any one can understand)



I have made myself some with qr codes for the address, however I found that they were harder for first timers to understand.
http://realbitcoin.info/cardblancemoblie/ shows the work needed to explain adresses as oposed to just having the value printed.

Is this what you ment or did I misunderstand?

Nice taught though, although it exists..

This is ok, but the amount and the qr code seems to be paper and can actually get wet!
that's some set back i guess

Cool. They look really nice! I wouldn't mind having a couple of those to give out as well.

They are waterproof, they have multiple layers..

1. alu coin
2. Qr private key
3. security sticker
4. protective clear sticker

The idea is that the cost is minimal so that the only real value is the bitcoin. This allows lower denominations.
