As the year begins, I am looking for ways to move gradually toward a more minimalist lifestyle. I recently ran across an item that can help - it's called the CardNinja and it is designed to add a wallet-like pocket on the back of your smartphone so you can slim down what you carry.
The CardNinja attaches to the back of your phone (or directly to your phone case) with some strong, yet safe adhesive. It holds fast, but can be removed without damaging your phone or leaving behind a sticky residue.
CardNinja has a flexible (stretchy) pouch on it and will hold 6-8 cards and some folded cash without interfering with the use of your phone. The profile is slim, so you can still put your phone in your pocket or purse and barely notice that the CardNinja is on there. Check out my gallery for some pictures.
I started out with a sort of teal-colored version and just ordered a black one so it will blend in a bit more in a business environment (there is a wide variety of color and designs to choose from).
It you're looking to slim down what you carry and possibly do away with your wallet, check out the CardNinja.
