Researchers are able to deliver messages and encrypted data via smartphone Compass

NFC, Bluetooth, Wi-Fi, mobile data "voice calls plain ole. Your phone no shortage of ways to connect with things, but that did not stop a group of Finnish scientists find a way to communicate through an integrated smart in your compass. Simply because they could.

Although NFC can transmit data up to 20 cm, the magnetic few inches diffuse messages - this limitation may help make payments more secure wireless.

The researcher said Vassilis Kostakos speaks to New Scientist that magnetic telephone exchanges messages system will mean nothing until they are within two centimeters (about 0.8 inches) from the station to pay. When you get the hardware is close enough, and can be thrown through a secure magnetic field code, and enable the application to pay for a wireless connection or NFC.



With encrypted data through variable magnetic field, the team was at the University of Oulu in Finland is able to provide web addresses (and even obsolete MIDI music files) of the electric telephone.

At 40 bits per second, and lifting heavy data will not happen here, but the group says it will be determined at a later date other applications this summer. We hope it will be Sophie and follows.
