Yes, you read it right. Why not buy stuff while helping the Linux cause? ;)

No annual fee. VISA only. And for every card activation the foundation will receive $50, and a percentage of the purchases you make. The only downside is that it's US only. :(

Here's the official links for it:

But is it open source?

I don't know... I don't know... I don't know... what to think of it. Somehow having a Linux branded credit card handed out by a "multi-billion dollar company" seems contraire to what Linux and open software stands for :/
On the other hand I would love to have a Tux branded Visa card.

Applied and.... rejected. Man my credit sucks!

Aw, that's quite a downside. It did seem too good to be true. Well, +1 for letting us know anyway - no doubt the USsians among us will find it worth investigating further. Think of the geek cred you would get with that.

ERROR NaN

:D

Can you imagine going on a date with a hot girl at a fancy restaurant, offering to pay and pulling out a Linux Foundation credit card?

To be fair, they tried that. But many customer's alterations meant the cards no longer fitted into the slot.

Now that is serious geek cred. Ba-dum-cha!

This is what's known as an affinity card. Just realize you are also supporting most likely B of A or US Bank in the bargain as well (in that order of likelihood). After looking at the website I'm going to go with B of A most likely as the US Bank stuff is all Java and this is .NET.
