This is the first ever NFC based Android Keyboard accessory, made by Elecom. This particular Android keyboard does not require a power source at all – just place your NFC powered Android device on it, and you’re good to go. It uses the NFC IP-1 protocol to connect to the device to any Android smartphone, though you do also have to download Elecom’s ATOK software on Google Play to be able to use it. It is also a bit expensive – at 18,690 Yen (or about Php 9345) it’s not the most affordable of Android keyboards out there.
