While it's a fascinating project I'd have some security concerns about plugging someone's USB business card into my computer.
That was my first thought. If someone gave me this at defcon I would not use it.

#12While I'm impressed by how low the bill of materials is, I can't but put into perspective the kind of skills the authors of the post has, and how mindbogglingly expensive they must be. Contrary to what the media says, it seems that the digital era has made (some) human beings more essential than ever ...
After reading the post, i was under the impression that the author really did some shopping for major components and assembled everything into a fun shape. Obviously i know nothing about electronic board design, so could you explain which extraordinary skill this required ?
EDIT : ok, i missed the part where he actually designed the whole board, obviously..

#13If you set aside the security concerns for a moment, this is a great way to make the first impression.

#14Waw, I wasn't expecting the components to be that cheap. That said I haven't bought such components in a very long while.

#15Most credit cards run Java(Card), another very interesting technology
On that note, the platform had a bunch of (medium) vulnerabilities early this year [0][1], but I haven't managed to find a follow up.
(Which isn't unusual - this is Oracle. Knowledge of patches is precious information.)

Well, it is appropriate as a business card for an embedded systems engineers, not so much for a system security one! More seriously, I never managed to understand the "obsession" with ROHS (this here is just an example): >I made sure to have a lead-free process—the boards, parts, and solder paste are all RoHS—so that I wouldn't feel bad about giving them to people. I mean, you are creating something that (besides bei…
Were I a system security engineer, I should think I'd have a sanitized way to plug in a USB device.
How else would one do forensics?

Embedded systems engineers are (usually) paid a lot less than full stack engineers.
Edit: I seem to be getting (a lot!) of downvotes on this. I thought it was quite well known, but apparently not.
Full Stack Engineer salary: $93,598 [1]
Embedded Software Engineer salary: $74,758[2]

I think it's very considerate to not add lead to a business card people may put in their pockets.

I meant - jokingly - the opposite, i.e. you call for a consultancy a security engineer as you are interested in increasing/bettering the digital security level of your business and he produces to you the Linux USB business card, you proceed to insert it in your computer and he says:
"Ah-ha!"
