I like the idea. It could help to introduce Bitcoin to people that are used to use fiat money in their daily life. Further, it is much easier to store Bitcoin as a value for long term investors (those also buy and store Gold at home). Of course, they could also use paper wallets but you need some technical knowledge to create them.

I just do not like the design. It remembers me more on vouchers than on fiat money. Maybe you should redesign it to make it more banknote-like.
