I'm not a lawyer, nor do I play one on the internet, but that does kinda defeat the purpose?

That aside, the icons are a bit nice, remind me of the ones in use by the Square app. Downsides are the lack of different sizes (only one is included: small), lack of a generic card, the rather strange cropping (for example "No Shadow"), and no grayscale versions.
