Technomancy

For the duration of the spell, you can tell if an item within 30 feet of you is a piece of technology. This penetrates physical barriers, but is blocked by 3 ft of wood or dirt, 1 foot of stone, 1 inch of common metals, or thin sheets of lead.

While this spell is active, if you touch a technological object for one minute, you learn it's function and become familiar with it (see technology rules).
