The Tamagotchi 4U is the last-born of Bandai. Put on sale the 27 September 2014 his distribution is performed exclusively in Japan.
With a color screen it also has the integration of the NFC (near field communication) technology. This lets you communicate with another Tamagotchi, but also to communicate with your phone (only if the phone has the NFC)

There is also a lot of accessories that allow to customize the tamagotchi. Among these we find faceplates, charms and finally Cards 4U. These allow you to download additional content.

In July 2015 a new version comes out, the Tamagotchi 4U+ which adds additional content to the original version.
