US Patent 9590352 Magnetically-implemented security devices

Security devices and methods of securely coupling electronic devices and peripherals are provided. In one embodiment, a peripheral has a first coded magnet on a first surface of a first device. The first coded magnet has at least two different polarity regions on the first surface. A second coded magnet on a second surface of a second device is also provided. The first coded magnet is configured to securely provide data to a device associated with the second coded magnet, if the first and second coded magnets' patterns are keyed to one another.
