This video outlines the Sony Family of NFC products available now.
Using NFC (Near Field Communication), you can transfer information between your phone and other NFC devices, such as phones, NFC tags or payment devices. For example, you can share web addresses, contacts, phone numbers, music tracks, videos or photos.
NFC tags are small programmed information areas that can be embedded on posters, on billboard advertisements or next to products in retail stores. Touching a tag can give you additional information such as maps, web addresses and movie trailers.
NFC is activated by bringing two NFC devices together. The maximum reading distance is about one centimetre, which helps prevent unauthorised communications.
