New Technology in DataExchange: Near Field Communication

      New Evolution of the Data Exchange world is Near Field Communication. Within 2 to 5 years NFC is most essential in all over world. 

  Near field communication, or NFC, allows for simplified transactions, data exchange, and wireless connections between two devices in close proximity to each other, usually by no more than a few centimeters.NXP Semiconductors and Sony in 2002, NFC technology is being added to a growing number of mobile handsets to enable mobile payments, as well as many other applications. It is expected to become a widely used system for making payments by smart-phone in the United States. Many smart-phones currently on the market already contain embedded NFC chips that can send encrypted data a short distance ("near field") to a reader located, for instance, next to a retail cash register. Shoppers who have their credit card information stored in their NFC smart-phones can pay for purchases by waving their smart-phones near or tapping them on the reader, rather than using the actual credit card.
