ABSTRACT
Sony and Philips are co-inventors of Near Field Communication (NFC). NFC works by magnetic field induction. It operates within the globally available and unregulated RF band of 13.56 MHz. NFC specifies a way for the devices to establish a peer-to-peer (P2P) network to exchange data. After configuring the P2P network, another wireless communication technology, such as Bluetooth or Wi-Fi, can be used for longer-range communication or for transferring larger amounts of data. With one tap of a mobile device equipped with an NFC chip, a user can make purchases, access information and services, set up conference calls with colleagues, and much more. It is all done without menus, wires, or complex setups. According to Philips, touching is the clearest way to tell a device what to connect to. For example, if one touches a stadium’s turnstile, it means “let me in.” If one touches a band’s “smart poster,” it means “let me hear a sample.”
