http://www.EETimes.com Near Field Communication, or NFC, allows smartphones to communicate with objects via radio when in very close proximity to one another. Now included in most new mobile phones, NFC enables applications like mobile payments, data exchange, location based tagging and much more. While security has long been cited as a reason consumers have thus far failed to pick up NFC in a big way, proponents of the technology have long argued that the system is in fact highly secure, with the phone's SIM card holding cryptographic keys to ensure secure transactions. We hit the show floor at mobile world congress (MWC) in Barcelona to find out more.
