Hey,

Is it possible to organize a very cheap and very massive production of plastic QR-code tags that users could carry as real life key-chain dongles, wallet cards and even tucking them to real life objects to sell or donate.

That would be massive invasion move into RL. After all everyone is expected to use bitcoin with their smartphone and all wallet apps do scan QR-codes.

The QR-code tag ideally should be tough and durable. Black and White could be not a paint, but (laser?) etching or dipping to show other color layer in two layered plastic (have no idea how expensive that is).

The challenge as I see it is to be able to make them all unique cheap as opposed to mass-production of identical things.

Any experts in the field?

Look in Thailand or China. ^^

But wouldn't have the user to submit his address first?

I'm not sure if that's what the OP had in mind. I'd think something more bling would be cool.

Actually gave me a cool idea myself  Tongue

How cheap do you need them to be?  A digital card printer can print black resin (virtually indestructible) on PVC card for about $0.15 ea.

You mean like this?

https://bit-pay.com/cards.html

I've got one on my keyring too.  credit-card durability plastic.  If you send me money I get a text message alert.  depending on my profile settings, the bitcoins can be forwarded to my wallet of choice, or cashed out and deposited into my bank account.

Best of all - if I lose this (or post it on the internet) the only thing someone can do - is give me money!



the front side is prettier

I really want these things dirt cheap. To give them away basically for free. You got to give people something physical in hands instead of paper bills to get bitcoin going RL.

The challenge as I see it is to be able to make them all unique cheap as opposed to mass-production of identical things.

Are you planning on printing the corresponding private key with the card?  Or are you thinking the Bit-Pay model where the card is tied to a hosted wallet service?

No, I did not wanted to put a private key there, only public bitcoin address. tbcoin did Smiley And it should not be tied to any particular wallet service, interoperateability is important.

I guess I could have worded my question a bit better.  How will you provide the private key to the purchaser of the card then?  e.g., another card, or on a piece of paper or what?  And then will it be mailed with the card, or sent electronically?

Well if you made them to order the buyer would already know the private key.

I believe the purchaser would just generate public addresses himself and keep his private key secret. All manufacturer need to know are public addresses after all.
