Universal accessory interface for mobile computing terminals

摘要

Described is an accessory for a mobile computing device which has a first interface. The accessory include a second interface and a third interface. The second interface compliments the first interface for mating therewith to enable communication between the device and the accessory. The third interface is substantially similar to the first interface for mating with accessories adapted to mate with the first interface. The third interface is mounted on a first outward facing surface of the accessory so that, when the first and second interfaces are mated, the third interface faces outward.
