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. | 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. | According to [http://www.wi-fiplanet.com/columns/article.php/1471871 Wi-Fi Planet]: "NFC reportedly would cost 20 cents per chip."

This new type of tag, the transponder tag, significantly lowers the cost of utilizing NFC for [[product identification]] by touching icons on the store shelf, which is the ''ultimate'' in usability among different identification schemes, since the shelves don't need to be wired for supplying electricity to the tags. | |||
