I love this concept for eWallet developed by the designer Mukai Shen. "eWallet is a shopper’s companion integrating WIFI and RFID technologies to connect to people and objects. The clamshell style device gives you the ability to window shop, customize details like color and fit, and even includes a built-in simulator to tell you how fabulous you look." The interactive device can be pretty dangerous for shopping addicts like myself, but the idea is just super cool! Curious to see when these will be on the market
