The US Patent and Trademark office has awarded Microsoft a patent on a wearable “electrical device” that uses your arm or finger as “transmission channel” to “transfer data through direct physical contact with another device like a computer, smartphone, or even a game console and controller,” writes Gloria Sin at Digital Trends blog. “The idea is that your body part acts as a conduit for the data to travel through, rather than beaming the information wirelessly, which makes it prone to hacking.” (via @greatdismal)
