With all the recent talk about surveillance and online security...this is an interesting idea: A USB Condom. It's a piece of tech that makes sure you are protected from viruses when you have to plug your smartphone USB cord into an unfamiliar computer or charging station for a little juice after your battery has died. The problem being solved even has its own term: juice jacking. This issue is that USB cables connect for both power and data. The USB Condom puts up a wall so the data bits from the phone and its partner never touch.
The USB Condom: unfortunate name, important innovation
