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 Smiley

Quote from the past -- Literally exactly 2 years ago I got this check. It's still in rather decent condition.

The edges are torn a bit, but honestly, it's held up pretty considering the amount of abuse I put it through (it was a bit larger than my wallet, so that's why the edges are torn, not to mention the amount of times I've folded / shown it to other people / etc...).

I am giving away checks again, I just got everything settled after hardware changes that kinda reset production, but things are back and moving. I do ask for a tweet if possible, or a share somewhere to try and help out.

I think the Firstbits are getting dropped all together, for good, and being replacing it with a custom label to verify the authenticity of the checks being printed by me on sight. Also this way i can use the same model to start developing Litecoin checks. =]

 I has thinking, a very fancy BTC hologram for the corner of these in place of the Firstbits line and obviously a fancy LTC logo for when I get that far.

I guess I am now open for submissions on a security logo.

Actually, a 0.00005430 tx for each check would only increase its cost by ~5 cents. Not sure about the fees though.
Good luck with your sales! I may order a few.
Thats fine, until they decide to change it again... lol I will look into it a bit more tho

Now taking orders again, this time the checkout is hosted to limit issues / downtime.

After a long break i decided to bring back the checks, except this time there will be no firstbits. Instead of charging more for the checks to cover the fees just to get firstbits, i figured id leave them off... So all checks will be completely blank until funded. Debating on selling funded ones...

Okay, so not only did i have a FirstBits issue from time to time, but now I can no longer fund my addresses to reserve them either.

i was wondering when this would happen, but it turns out my transaction amount is to small by the blockchains standards... IDK how to combat this so looks like I'm boned.

Site is currently down due to a Comcast outage.

Why on earth are you hosting your website on Comcast? A great VPS provider, Linode, is only $20/month for a 1GB VPS. $20/month is well worth the cost if you are serious about your business. $25/month for automated backups is even better.

*Disclaimer: I am a Linode customer and I linked to my affiliate link.
I ask myself the same question... I've hit the wall with Comcast and am looking for a alternative currently.
inmotionhosting.com . By far the best ive used in 13 years. Let me know if you need any help. Also i am ordering a stack of these when your site comes back online. Love them.

I have been getting asked "How do I import this into another wallet?" Assuming you dont use Mt.Gox or Blockchain.info or another wallet that allows you to import mini private keys, you can convert your mini key to Wallet Import Format using Casascius Bitcoin Address Utility.

A portable, zipped, executable this utility should do everything needed. (Also it works in Linux using Mono!)

Would you be willing to sell a single one as a sample, or give me one just to check it out before I buy more

A bit over due, but you can now add custom slogan / footer to the bottom of your checks to personalize them.
