Not everyone wants to fly their geek flag in view of the general public, sometimes you want to vet a person before revealing your nerd tendencies. When you do feel comfortable that your techie ego won't be pummeled with ridicule, you can whip out this nifty NES Controller Business Card from Banpresto.

Of course some people won't get the pure style genius this represents, but for a mere 2,900 yen ($30.79) the cool points you'll score over time will be worth it. You can pick yours up here.
