Design looks nice, but the card value should be denominated in BTC, not dollars.
+1. Design is beautiful, but unless you're preparing a system where the cards are essentially prepaid cards to deposit money in an exchange, denominating in BTC is much easier for the end user.

I didn't realize there was a website for redeeming the codes - thought maybe there was a private key on the card or something.
Now I'm totally loving your concept!
So - does the card buyer pay a premium to buy the card ($105 to buy a $100 card), or do you take a cut when the user exchanges their code for bitcoins?
