When designing wallets, my partner and I were careful to combine one’s phone with their wallet. When leaving the house most people leave needing their keys, phone, and wallet. By connecting 2 of the objects it makes ones life easier because the phone and wallet are already together. The first prototype depicts a phone case with an attachable coin purse. The second, is a phone case that doubles as a charger and wallet. The third, is a large wallet that allows room to fit the phone within the pocket.
The prototyping process is fun. I allows me to get an understanding of the form and function of the product before the real thing.
