Japan's Elecom is launching One2Touch's portable keyboard that connects with your handset via near field communication (NFC) and can be folded and kept while not in use or needed.

The device that was announced earlier this year is described as the word's first full-size keyboard for smartphones that does without cables, pairing, and battery charging; the internal battery lasts about 18 months.
The device works with Android and the NFC IP-1 protocol. You simply plonk your NFC handset in the middle of it and start banging away on the keys. The device will be launched in late August and it's expected to go at $240 including a carrying case.
