What is NFC? A set of standards which define the exchange of data via radio within close proximity Two active devices (phones) can exchange data bi- directionally. Active devices (phone) can read passive devices (tags) NFC Record Type Definition’s (RTD) define a set of well know data types for exchange  Text  URI  Generic Control  Smart poster (Text +URI)  Connection Handover @CHRIS_HACKETT

Why do we keep hearing about if? (for years) Builds on RFID which is now secretly all around us  M & S (Stock tracking)  Car park tokens / Building access Cheep tags  For many applications at the point of disposable pricing  Small and can be put into many product Financial  Mobile payments  £233b (2011) annual UK Credit/Debit spend The UK Cards Association  Who would like a % of this? @CHRIS_HACKETT

Eureka Moment Hype, doesnt seem anything special Until … A NFC phone, as an active device, can write on blank tags. Now its interesting @CHRIS_HACKETT
