The mistery of the Braun Toothbrush

I have an electric Braun 'ultra plaque remover' toothbroosh, and it has a mistery that has bothered me for years. It seems that neither the brush nor the base (the one who's plugged to the wall and electric current) have metal contacts to charge the batteries. Still, when you put the toothbrush close enough to the base, the 'charging' led turns on. Why's that? How does it do to transmit the electricity and charge the battery without metal contacts?

I have a Panasonic ES4000 electric shaver and it also has a contactless recharging system. Nifty system.
