Bitcoin Checks : R3

[bluefirecorp]

I got mine.

First thing I tried was looking at the private key. Just using a light in the background (the sun), I was able to see about half the private key. With a magnifying glass, I could probably see the entire key without too much trouble.

(Example of this security flaw irl:
You lose your 'checkbook', someone else finds it, writes down all the public keys/private keys, hands you back your 'checkbook'.
As you fill your checks [to use them], someone else just jacks the money.)

Really, it's an uber neat check

Some of it is probably from the type of printer I'm using, a laser would be better I think.

Its a beautifully done check. I have a few people in my area I could convince to accept something like this. I will keep everyone posted.

Where do you get your scratchoff stickers from?

[Kansattica]

Applied for a freebie. This certainly seems interesting, and I want to see where it goes.

@OP

what's new with your checks compared to printcoins.com ?

I thought the printcoins checks were very well done (ordered a few last year)..

I just set out to design something more modern and convenient for everyday use of hand to hand transactions. Plus having more options for the community can't hurt either.

... I never thought it would be so hard to give something away for free on the internet, lol

Got mine in today, this is a really nice product. It looks and feels just like a regular check. It has micro-print (says PRODUCTIVITY SYSTEMS Q7), water marks and the scratch off holographic stickers cover the private key very well. It got here very fast, as I ordered June 3rd.

So I spent all day coding and got a better checkout system working. Nobody should have to email my lousy forms again, click the button and off it gos. Automated payment addresses now work and you will also get a carbon copy of your order... but check your spam.

I know my status wasn't great which is why I am giving away samples.
The store page just got better so you can check that out. http://shop.psjb.me
When I start selling more and people find more ways to use them I will offer bigger packs, but at the moment it doesnt seem practical.

can you do customized version for me ? (IBB logo on it )

like so here http://www.youtube.com/watch?v=DR_zDrzhPgE

Would you like me to do another run of those? Printcoins.com is now selling bills again.

[TehZomB]

could you also add a covered barcode for the private key, for those of us too lazy to type?

I was actually just thinking the same thing.

Unfortunately I cant seem to get that much information, that small and consistently legible by a scanner as a barcode... I might have a new idea that'll do something like this, We'll see.

Qr codes work great

Agreed, but doesn't quiet work with the current design. Since not everyone can scan, I need the QR and plain text to be functional, but thats to many stickers... These weren't meant to be mass imported, I'd have to make one specifically for that. But when you go down that road I think Casascius has the best idea, paper wise. https://en.bitcoin.it/wiki/Casascius_Bitcoin_POS_system
