Most people don't know much details about things they own. They don't know the model of their router, they don't know the CPU in their laptop, they don't know the version number of their phone OS. What do they do? They usually turn the thing upside down (or go to the "device info" section) and find the data there. Snapping a picture or the sticker on your fridge/dvd/lawnmower is probably quicker than writing it by hand.

If the user can see these informations, he can take a picture of it. If he can't, well most people probably wouldn't know either.

Also, nothing stops you from taking a short video of the item and saying additional information out loud.
