Halo by Fitorio Leksono is electronic device that is made strictly for the purpose of trading business cards. This digital device allows people to exchange their cards with basic touchscreen and Bluetooth technology.
The small gadget looks a bit like a slimmed-down smartphone with a protective rubber case on the back. The front is made of crystal glass that is a touch-screen. People can give and collect business cards using a Bluetooth. To find any card they've collected, one can scan through the alphabetic index. Most importantly, this device still allows people to make custom business cards to make sure one can still stand out from the crowd.
This gadget is currently only a concept but making it real would allow us to say goodbye to paper cards.
