This technology 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. It is expected to become a widely used system for making payments by smartphone in the United States. Many smartphones 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 smartphones can pay for purchases by waving their smartphones near or tapping them on the reader, rather than bothering with the actual credit card.

It simplifies

• File sharing
• Electronic business card
• Electronic wallet
• Mobile payment
• Parking ticket
• Boarding pass…etc

Pairing is easy..not like Bluetooth or Wifi
