When you get a smartphone you have to buy a case to keep it safe. The same goes for your wallets and cards. And then you need a spot on your keychain for your flash drive. And you just drop that loose SD card in your pocket. Nerd Herder wallets just put it all in one place to save you the trouble of different locations and the cost of multiple points of storage.
Like a good go-bag, the Nerd Herder wallet has a variety of pocket sizes. One fits your smartphone (available in multiple sizes for those of us with larger devices), another can store money or headphones, and you've got a couple of small slots for flash drives and SD cards. Each wallet also comes with a card insert so you can store a few credit and ID cards if you want to go the more traditional wallet route. A hook up top allows you to attach the Nerd Herder to a hook in your bag for a little added safety.
Minimalists will probably hate this wallet at first sight, as it holds a lot and carries more than just the essentials. It does consolidate a lot into one little fold, however, which might offer a more minimalist approach to those who don't want to spread out their stuff. Plus, if you want something smaller, you can just go get a rubber band. If you want a handy way to keep your most-used tools and your money in one place, you should check this one out.
