An Apple patent application published by the U.S. Patent and Trademark Office on Thursday describes an intelligent magnetic attachment system that provides an interface for an iPad to connect and communicate with a variety of accessory devices, including other iPads. Apple’s patent for a “Magnetic attachment unit” has a basis in the keyed magnetic mechanism present in all iPads. Currently, Apple uses the internal magnet arrangement as a simple anchor point for Smart Covers or Smart Cases, but the proposed invention takes that idea much further.

Finally, there’s mention of wearable tech that could be used to trigger the magnetic sensor and prompt various behaviour from the iPad. This could take the form of a ring, for instance, which when worn by the user would do things like unlock the iPad when the hand it’s on is waved deliberately across the tablet’s screen. In the context of other Apple wearable rumors making the rounds, this could theoretically also work with magnetic connectors built into some kind of iWatch, possibly for identification and unlocking purposes as well as for simple proximity-based communication with certain apps.
