They look nice, but are not at all secure. The generic hologram might as well just be a scratch off sticker.

We trust Mike ( https://www.casascius.com ) because he has been around for a long time, has earned our trust and has gone to great lengths to describe his private key handling process. Also he has published his real name and address etc.
Who are you that we should trust you with our private keys? What is your private key handling process? This entire system rests on your ability to convince us that we can trust you.
I REALLY like the idea and would like to buy some but I need to know a lot more about you personally before I do.
Are you willing to publish all your real life information?

You can't have a double standard like that. There is absolutely no reason to trust Mike anymore or less than these people. They can all screw you over.
The only safe way to do this is a way that even the bill/card/coin maker has no idea what the wallet information is.

I am likely missing something, but how would a merchant know if you funded the bill?
The checkmark signifies that you funded it. This is verified with the QR code in the upper right hand corner (check out the first image) and it is a url to the balance at blockexplorer.com.

They simply scan the QR code

Update - Feb, 2012
Due to the increase in valuation, printcoins is now offering 0.1 BTC bills which are about equal to a $2 bill. Bills that are greater that 10 BTC have been taken offline. Also Ron Paul bills have been discontinued.
Update - Aug, 2012
You can now print your own: http://print.printcoins.com/
Update - Feb 28, 2012
These will now only be sold in bulk orders of 100. This will likely change back in May, but for now, the small orders are just not worth the time. I would like to sell plastic credit card format printcoins, so let me know if you would like to do bulk orders of these.
Updates - Jan 4, 2012
* Due to the rise in the value of bitcoins, bills are now cheaper (prices automatically adjust to mtgox)
* Denominated bills are back up for sale
* Paper stock is now significantly heavier - 32 lbs, 100% cotton
* Hologram size is now 12% larger
* Denominated bills are sold pre-funded. You don't fund them yourself.

Physical Bitcoin Bills at http://printcoins.com
About
PrintCoins are a way to bring your bitcoins into the physical world.
PrintCoins come in a variety of denominations, each with their own color scheme based on standard poker chip values. And they are printed on 24lb paper that is made from 100% cotton.
There is also an "open" denomination bill that can be used like a blank check. You simply fund the bill with a specific amount, and then write the amount on the bill.
All bills come unfunded so your bitcoins remain in your digital wallet until you need them to fund the bills. To fund bills, you can use the public addresses sent to you via email when your order is shipped, or you can just scan the bill with a smartphone bitcoin wallet app (Android Wallet or InstaWallet).
Perfect for . . .
