==General info== '''Near Field Communication Technology''' (NFC) jointly developed by [http://www.sony.net Sony] and [http://www.philips.com/ Phillips] was approved as an [[ISO]]/IEC standard ([[ISO 18092]]) on 8.12.2003 '''[http://www.nokia.com Nokia]''' has also joined in the consortium to develop NFC and press reports say we can be expecting consumer products later in 2004. Essential specs: *Maximum working distance: 10'''cm''' (4 inches) *Speed: 106kbps, 212kbps or 424kbps *One-way or Two-way communication *NFC can be used to configure and initiate other wireless network connections such as?[[Bluetooth]] or [[Wlan]] *Data is read utilizing [[load modulation]] whatever that means '''New specs:''' In addition to the original modes of Active (two directional) and Passive (one way) communications it is now apparent that they have introduced a third mode of operation: A [[w:Transponder]] ie. the tag gets it's power from the other device which enables tags without batteries and electiric grid access to communicate information as a NFC device with power is brought into range [http://digital-lifestyles.info/display_page.asp?section=distribution&id=1744] This could be very useful in [[product identification]] if embedded into shelves and mobile phones. According to [http://www.wi-fiplanet.com/columns/article.php/1471871 Wi-Fi Planet]: "NFC reportedly would cost 20 cents per chip." But this should propably be taken in the light that in around 2000 it was reported that [[Bluetooth]] radio would cost 5$/unit in 2003 and considering that to the price of around 50$ for an USB dongle in that time. ----
