With near field communication technology shaping up to be the number one new feature on handsets and mobile devices starting next year, a Japanese carrier is already planning on releasing limited NFC functionality to the iPhone 4. Softbank is set to debut a NFC sticker or “seal” which will cover almost the entire rear of the device without preventing the use of Apple’s Bumper cases. While the NFC sticker doesn’t appear to interact with the iPhone in any way, it will reportedly allow iPhone 4 users in Japan to interact with some of the most common mobile payment solutions. The NFC sticker is made of polyurethane, is 0.5 ounces in weight, and should be available for $36 starting in February from Softbank in Japan.
