I bought a Wii U used yesterday and it came with an official charging cradle that has some kind of computer chip on the front. Pictures in the spoiler for a side by side comparison with a normal charging cradle.
Is it some kind of RFID chip? I did some (brief) research about Renesas and it seems to be a Japanese chip maker that makes components for the Wii U.
