Your Next Phone Could Communicate Using Magnetism

3G, NFC, Bluetooth and Wi-Fi are all well and good, but there’s perhaps an even geekier wireless protocol in town — and it uses magnetism for your phone to communicate.

Everyone’s most beloved of science phenomena since the high school science fair, the neat thing about using magnetism to get your phone transmitting data is that it already has the sensors on board. The developers of Pulse are using the magnetometer on phones, usually used to measure direction suing the Earth’s magnetic field, to receive information by varying the magnetic field in the surroundings of the phone.
